Upload Eclipse to Current Repo on Github

This tutorial describes the usage of the Eclipse IDE to perform Git operations.

1. Git support for Eclipse

Via the Eclipse IDE you can perform Git commands like staging, commit, merge, rebase, pull and button.

2. Installation of Git back up into Eclipse

About Eclipse IDE distributions from Eclipse.org already incorporate support for Git. In this instance no additional installation is required.

If the Git tooling is non available, you can install it via the Eclipse installation managing director. Select the menu entry. Enter one of the following update site URLs:

                # Use this update site to get the latest release http://download.eclipse.org/egit/updates  # use this update site to get the night build http://download.eclipse.org/egit/updates-nightly/              

The dialog to install the Eclipse Git squad provider is depicted in the following screenshot.

3. Configuration for Git usage via the Eclipse IDE

Interoperability of Git control line settings with the Eclipse IDE If yous accept already configured Git for the command line, no boosted setup is required in the Eclipse IDE and you lot can skip this practice. The Eclipse IDE uses the same configuration files equally the Git command line tools. This makes it easier to use the Eclipse Git tooling and the control line tooling for Git interchangeable.

3.ane. Configure user and email

In your Eclipse IDE, select the entry. Configure your total name and email in the user settings. As the Eclipse IDE uses the aforementioned settings every bit the Git command line, this might already exist done.

For the user the user.name fundamental is used, for the email the user.email primal is used.

If these keys are not available press the Add Entry…​ button and add them.

Repeat the procedure for your email address via the user.email key.

3.2. Configure Git to rebase during pull operations

To utilise rebase during the pull operation set the pull.rebase parameter to true. It avoids merge commits if you pull from a remote repository and have divergent changes and instead rebases your local co-operative on the remote co-operative it tracks.

This is recommended setting by the writer of this text.

3.3. Validate the setup

After this setup, the configuration should look like to the post-obit screenshot.

3.iv. Configuring the proxy settings

If you are using a proxy server, you can configure it via .

four. Exercise: Working with Git repository in Eclipse

The post-obit exercise explains how to employ the Eclipse IDE to perform Git operations. To ensure that you lot have a Git repository, you lot first create a new local Git repository via the Eclipse IDE.

The Eclipse workspace and Git repositories It is good practise to place your Git repositories outside the Eclipse workspace. This separates your Git repository from any additional meta-information which Eclipse might create. By default, Eclipse Git uses the git binder in the users home directory to clone new repositories.

4.1. Create a new Git repository via Eclipse

Open the Git Repositories view via the menu entry. From the toolbar, select the Create a new Git repository and add together it to this view entry.

This opens a dialog which allows yous to specify the directory for the new Git repository. Select a new directory exterior of your workspace. By convention, this directory is a subdirectory in the git folder of the users home directory.

Printing the Create push button. At present the Git repository is created and a reference to it is added to the Git Repositories view.

4.2. Create .gitignore file

We want to ignore certain file types in our Git repository. We want Git to ignore the bin folder and *.grade files.

Create a .gitignore file in the superlative-level folder of your Git repository. This means, the file should exist placed at the same level as the .git directory.

Eclipse Git does not permit to create a file directly in the top-level folder of your repository. You have to do this step outside of the Eclipse IDE, either via the control line or via your organisation project explorer.

It should contain the post-obit content.

Contempo versions of MS Windows decided to prevent you lot from renaming a file in the file explorer without using a file extension. Create a file in Notepad or Editor (new proper name for Notepad) and select Salvage-As. Ensure yous have removed the .txt extension.

4.three. Create a new project

Create a new Java projection called com.vogella.git.start via the menu entry.

If yous are using Java 9 or higher, you will exist asked to create a module-info.coffee. The post-obit dialog is not shown if you use Java 8 or lower.

Right-click on the source folder and select and create the com.vogella.git.get-go package.

Right-click on the bundle folder and select and create the following class.

                                      package                    com.vogella.git.first                    ;                    public                    class                    GitTest                    {                    public                    static                    void                    main                    (                    String                    []                    args                    )                    {                    System                    .                    out                    .                    println                    (                    "Git is fun"                    );                    }                    }                                  

4.4. Put project under Git version command

To put your new projection under version command with Git, right-click on your project, select .

If another version control organisation is installed yous take to select that you want to use Git every bit a version control system.

Afterwards, select your existing Git repository from the drop-down list and press the Finish button.

Printing the Finish button. Your project is now moved to your Git repository.

The post-obit screenshot shows the directory in the Git Repository view. The .git directory contains the Git repository, the other directories comprise the files of the working tree.

4.five. Using the Git Staging view for the initial commit

Open the Git Staging view, via . In this view drag all files into the Staged Changes expanse, write a meaningful commit message and printing the commit push.

4.6. Alter a file and commit the change

Change the Organisation.out.println message in your GitTest class.

                                      packet                    com.vogella.git.showtime                    ;                    public                    course                    GitTest                    {                    public                    static                    void                    main                    (                    String                    []                    args                    )                    {                    Arrangement                    .                    out                    .                    println                    (                    "Git is cool"                    );                    }                    }                                  

As well create a new file called Readme.adoc.

Commit the changes of the GitTest grade but practice not add and commit the Readme.adoc file to the Git repository.

In the Git Staging view drag only the GitTest class into the Staged Changes area, write a meaningful commit message and press the commit button.

This change is at present also stored in your local Git repository. The Readme.adoc file is neither staged nor committed to the Git repository.

4.7. Commit more files

Commit the Readme.adoc file. By now yous should know that you have to stage the file and commit information technology.

four.8. Configure the History view

Open the History view via the menu entry.

In the History view click all toggle buttons as shown in the screenshot

• Link with Editor and Selection

• Show all changes in repository containing the selected resources

• Bear witness all Branches and Tags

Afterwards, utilize the History view to review which files were included in your private commits.

4.9. Open up an older version with the electric current version of a file via the History view

We want to see the version of the GitTest.java file as it was in the showtime commit. Select the first commit in the history view, find the file selected in the commit and select via the context card.

four.ten. Accidently add a unwanted file an remove information technology

Create a new file nammed test.unwanted via right mouse click on your project and New → File from the context card. Stage and commit the new file.

Now add together *.unwanted it to your .gitignore file. Make a change to your examination.unwanted file

Git shows it every bit modify, as changes in .gitignore only apply to new files You need to untrack the file.

Select the file and select Squad → Untrack (or Team → Advanced → Untrack on latest Git support for Eclipse).

Stage and commit the modify.

four.11. Add together more than projects to your Git repository

You can of course have multiple projects in a Git repository. To validate that, create two more Coffee projects called com.vogella.egit.multi.java1 and com.vogella.egit.multi.java2. Create at least i Java class in each project.

Afterward select the new projects, right-click on them and select .

Select your Git repository in the following dialog and add together both projects to this repository. Printing the End push.

4.12. Validate the project move and commit changes

Afterwards validate that the projects have been moved. You can checking your workspace directory and your Git repository directory via a file explorer. You run across that the projects have been moved from there original location to the Git repository.

The changes have not yet been committed. Now commit all files in the two projects to your Git repository.

5. Do: Clone an existing repository

In this practice you will clone a Git repository and import the existing projects from this repository into your workspace.

For this, select .

Select Clone URI in the next dialog.

Enter the URL to your Git repository which you want to clone. Y'all tin can employ the following example URI.

git://github.com/vogella/eclipse4book.git

Git supports several protocols, eastward.m. git://, ssh:// and https://. Y'all can paste the clone URL to the first line of the dialog, the balance of the dialog is filled based on this data. Some proxy servers block the git:// and ssh:// prThe to a higher place link uses the git protocol, alternatively yous can as well utilize the http protocol: http://github.com/vogella/eclipse4book.gitotocols. If you face bug, please try to use the https:// or http:// protocol.

After pressing the Next button the system will allow you to import the existing branches. Select at least the main co-operative.

The side by side dialog allows you lot to specify where the repository should be copied to and which local branch should be created initially.

After the Git repository is cloned, you can import existing projects.

One time this dialog is completed, you have clone the remote repository into a local Git repository. You tin use Git operation on these projects.

The project may non compile, as you may miss pre-requisites. For this exercises, this tin be ignored, the purpose of it was to learn how to clone a repository.

6. Practise: Import projects from an existing repository

If you have already an existing Git repository you lot can add it to the Git Repostory view. After you can import the projects into your workspace via the carte du jour entry.

Select Local if you lot want to important from a local repository or Clone URL if you first want to clone the repository.

The following screenshot shows multiple local repositories. To import the project contained in one of them, select i entries and printing the Next push button. To add a new local repository to this dialog (and the Git repositories view) use the Add…​ button.

The wizard allows you to specify the projects to import. After the import the Eclipse IDE is aware that these projects are function of a Git repository.

7. Exercise: Using interactive rebase in Eclipse

Git allows to adjust the local commit history via the interactive rebase functionality. Eclipse provides support for simplified versions of this also as support for full interactive rebase operations. This includes changing the gild of commits or combining, removing and adjusting commits.

7.i. Elementary interactive rebase operations available via the History view

To reword a commit, right-click on it in the History view and select to change the commit message.

You tin can squash several commits by selecting them in the History view. Select afterwards the menu entry from the context menu.

The above options are simplified means to do an interactive rebase.

seven.2. Performing a total interactive rebase via Eclipse

To start the full interactive rebase open the History view and click on the context menu. Select the last commit preceding the oldest commit you want to rewrite. Oftentimes this is the one origin/master points to.

This opens the Git Interactive Rebase view. The Git Interactive Rebase view allow you perform the full interactive rebase functionality.

It shows the rebase program populated with the commits to be modified. They are sorted in topological order of the sequence in which they will be processed. This guild is the reverse order which you see via the git log command or in the History view. The initial action for all commits is "Pick".

The following deportment are available.

Table i. Interactive rebase actions

Activity	Description
pick	includes the selected commit, moving pick entries enables reordering of commits
skip	removes a commit
edit	apology the commit
squash	combines the changes of the commit with the previous commit and combines their commit messages
fixup	squashes the changes of a commit into the previous commit discarding the squashed commit'southward message
reword	similar to choice but allows modifying the commit bulletin

Use this view to finalize the rebase plan. For instance, y'all can reorder commits with the pointer buttons and select the rebase action y'all want to utilise to the commit. The following screenshot demonstrates a possible selection.

When the rebase plan is finalized, click the First push to kickoff the interactive rebase command. Eclipse Git processes the plan. It stops at all commits with an activeness which needs user feedback. For case, the reword action which requires entering the new commit message. The dialog for irresolute the commit message is depicted in the following screenshot.

Here is the result of the rebase functioning displayed in the History view.

If something goes incorrect during the rebase operation, you lot can select Abort in order to stop the rebase operation and curlicue back to the starting point.

viii. Eclipse Git configuration

The Eclipse IDE uses the default Git settings, e.1000. done via the command line tooling. You tin also employ the Eclipse IDE to configure these options.

eight.one. Git user settings in Eclipse

To use Git you must configure your full name and electronic mail address. This information is used to fill the writer and committer information of commits yous create. These Git configuration settings can be adjusted via the Eclipse preference setting. Select to see the electric current configuration and to change it.

eight.two. Default clone location

If you clone a new repository via the Eclipse IDE, it volition exist cloned by default to a new sub-binder in a default directory. This default path can be configured via the entry in the Default Repository folder field.

You lot can as well use Eclipse configuration variables to define the path, east.one thousand., if you desire to store repositories in the folder "git" under the Eclipse workspace you may use ${workspace_loc}/git.

8.iii. Configuring the toolbar and the carte du jour for Git usage

To simplify access to the common Git operations you lot can activate the Git toolbar. For this select and check the Git and Git Navigation Actions entries in the Activeness Set Availability tab.

After you can configure which Git operations should exist bachelor via the Tool Bar Visibility or the Carte Visibility tab.

viii.iv. Eclipse support for SSH based authentication

Yous can create an SSH key pair in Eclipse for SSH based communication. This tin be done via .

9. Details on the Git views

9.1. Using the Git Repositories view

The Git Repositories view allows you to scan, add. initialize or clone repositories. It also allows to import projects, manage your branches and much more than. You tin can open this view via

The toolbar let you to:

• add an existing local repository to the view

• clone a repository

• create a new repository

The content surface area of the Git Repositories view shows the existing Git repositories and the important information of each repository. The post-obit screenshot shows an instance entry.

A right-click (context carte) on an element in the Git repositories view allows y'all to perform related Git operations. For example, if y'all right-click on a co-operative you can checkout the branch or delete it.

9.2. Using the Git Staging view

The Git Staging view allows staging and committing likewise as reverting changes.

This view presents which files you accept touched and which files will be included in the next commit. Unstaged Changes lists those changes which you have washed locally but which you accept not yet added to the staging area. Staged Changes list those changes which you already have added to the staging area. You can drag and driblet files from ane surface area to the other. To commit the staged changes you write your commit message and press the Commit button which is highlighted in the post-obit screenshot.

Yous can switch between different repositories or even restart Eclipse without losing a commit message and it allows incremental staging for changes.

Y'all tin can open up the Git Staging view via the menu.

nine.iii. Git integration into the Packet and the Project Explorer

The Package Explorer view shows indicators on the files to show their status. The most important icon decorators are depicted in the post-obit screenshot.

The file name describes the country of the file from the following table:

Tabular array 2. Git label decorations

Land	Description
tracked	File is committed to the Git repository and has not changed.
untracked	File is neither staged nor committed.
ignored	File is flagged to be ignored by Git operations.
dirty	File has inverse since the final commit.
staged	Changes in the file will exist included in the next commit.
partially-staged	The resource has changes which are added to the index and boosted unstaged changes in the working tree
added	Staged merely non yet committed, i.east. snapshot of this file has been stored in the git database. This condition is the same as the staged status, simply the file wasn't nether Git version control earlier.
removed	The resources is staged for removal from the Git repository.
conflict	A merge conflict exists for the file.

A combination of the staged and dirty condition ways: some parts of the inverse file have been staged while some are still unstaged. This can happen if you lot stage a file and then again change the file before creating the next commit. You can too change the staged parts using the compare editor opened past double clicking files in the staging view.

On a project level the explorer view adds the information which Git repository is used to the project proper name. It also adds the number of commits that are different between local and remote tracking branch. This way you tin rapidly see if your local branch is alee or behind the remote co-operative it is tracking.

9.4. Using the History view for viewing the Git history

9.4.i. Purpose of the history view

The History view allows you to analyze the history of your Git repository and to meet to which commits the branches and tags points. This view displays writer, date, commit bulletin and the modified files of a commits.

This view is depicted in the post-obit screenshot.

You can open up this view via . Alternatively yous can open it via the repository node in the Git Repositories view. For this click on the entry. Some views, e.m., in the Java EE-Perspective, practise not accept this shortcut, in this instance use .

To meet the history of a resource, select your project, a file or a folder, right-click on it and select the Testify in> History context menu entry. Culling you lot tin can use the Alt+Shift+W shortcut and select the History entry.

Y'all can also configure the History view to display the history of the current selection. Select the highlighted push button in the following screenshot for that.

If you select a commit you run into the commit message and the involved files.

Via right-click on an private file yous can compare this file with its antecedent (the commit before that) or with the current version in the workspace.

If the "compare mode" toggle is selected from the view card of the History view you can also double click a file to compare it to the previous version.

9.4.two. The History view filters

The History view has quite some options to configure which commits are displayed. Its toolbar allows y'all to customize which commits are displayed. By default, the History view filters the history based on the current selection and shows only the active branch.

If you lot work with several branches, eastward.g., because you are using Gerrit for code reviews, you typically want to see all branch information and remove the filter based on the resource.

The History view allows you lot to filter based on resources. See the tooltips of the toolbar for the meaning of the dissimilar filter options. In lodge to see all commits click the highlighted buttons with the Show all changes in this repository and Testify all branches and tags tooltips.

The following listing gives an overview of the purpose of the unlike buttons.

Depending on your use case yous may want to select the following option:

1. testify simply those commits which are reachable from the current branch. Hide all commits on other topic branches.

2. see simply those commits which inverse the selected resource (file, project, subfolder) or it'due south children. E.g. display just those commits which touched the selected java file. The current option is shown in the top right corner of the History view.

3. see just those commits which changed anything in the parent folder of the selected resources (file, project, subfolder) or it'due south children. E.thou. display simply those commits which inverse the same package as the selected java source.

4. run across only those commits which changed anything in the same project as the selected resource or it's children. Used when you lot are working in a repository which contains multiple projects.

5. don't filter at all. Show all commits of the electric current repository

The options b., c. and d. are tied to the currently selected resources. Button g. allows that the history view automatically updates when you change the selection.

If you got lost with the different filters and the history doesn't evidence what yous look, set information technology dorsum to show everything. Therefore make sure that Show all branches and tags (a) is turned on and Testify all changes in repository (e) is selected.

9.4.3. Using search

You can also search for commits based on committer, author, ID or comment. For this plow on the Show Find toolbar (f) and type in a search string in the Find field. The commits fitting to your search are highlighted. You can combine this search with the filters explained above.

The Git Search bachelor in the menu is much more than powerful and consumes less memory since information technology doesn't demand to also display the history.

ix.4.4. Showing details of a commit

If you want to encounter more details most a commit, right-click it and select the Open in Commit Viewer entry.

9.five. Commit Viewer

The Eclipse IDE allows to view the content of a commit. For example,if you are in the Git repositories view you tin can open a commit via the primary Eclipse carte. To practise this select the menu entry.

If you open a commit you lot can create a tag or branch from it. Y'all can likewise revert it, blood-red selection information technology or check it out. You can as well reveal it in the history view.

10. Performing Git operations in Eclipse

10.1. Pull, button and fetch

You can apply the Git Repositories view to pull, push and fetch to remote repositories. Right click on your repository and select the appropriated operation.

10.2. Basic team operations

Once you have placed a project nether version control you tin first using team operations on your project. The squad operations are available via right-click on your project or file.

The Team bill of fare is also available from the context carte du jour of an opened editor.

The most of import operations are described in the post-obit listing. Select:

• , to add the selected resources(s) to the Git alphabetize

• , to open the commit dialog to create a new commit

• , to create a patch

• , to apply a patch to your file system

• , to add a file to the .gitignore file

• , to display the history of the selected resources(s)

x.iii. Team operations bachelor on the project

If you select a project you tin apply additional team operations from the context menu.

• to pull in changes from your remote Git repository

• to fetch the current state from the remote repository

• to checkout existing or create new branches

• to push changes to your remote Git repository

• to create and manage tags.

ten.4. Amending a commit

Git amend allows adjusting the final commit. For example you can change the commit message or add some other modification.

The Git Staging view allows you lot to perform the Git amend command via the highlighted push in the following screenshot.

10.5. Creating and switching branches in Eclipse

Correct-click your project and select to create new branches or to switch between existing branches.

Y'all tin also switch branches in the History view or the Git repositories view.

10.6. Starting a merge functioning in Eclipse

Eclipse supports merging of branches to add the changes committed on one co-operative into another branch.

Checkout the branch into which y'all want to merge the changes into and select your projection and to offset the merge dialog.

10.7. Rebasing a branch onto another co-operative

The Git Repositories view allows you to rebase your currently checkout co-operative onto another co-operative.

Right-click on a repository node and select equally depicted in the following screenshot.

In the following dialog yous can select the branch onto which y'all want to rebase.

You can too select the branch to rebase onto from the Branches node of the tree direct.

If the rebase was successful a dialog is shown. You lot have to resolve rebase conflicts if they occur. After resolving them, select .

If you want to skip the alien commit and proceed with the rebase performance use .

To abolish the rebase operation select .

10.eight. Solving conflicts created past merge, rebase or other operations

If during a Git performance, ii changes are alien, y'all take to solve these conflicts manually. Eclipse highlights the affected files in the Package Explorer and Projection Explorer view.

Eclipse Git supports the resolution of these merge conflicts.

To trigger this via the explorer views, right-click on a file with merge conflicts and select .

Y'all can also use the Git staging view to find the conflicting files. In large projects this is usually faster than navigating the Package Explorer or Project Explorer view.

This opens a dialog, asking you which merge fashion you would like to use. The easiest mode to meet the conflicting changes is to utilise the Use Head (the last local version) of alien files as merge manner. This mode you see the original changes on the left side and the conflicting and non-conflicting changes on the right side.

Y'all can manually edit the text on the left side or utilise the Re-create current change from right to left button to re-create the changes from correct to left.

Eclipse also allows to show the mutual ancestor of both commits to brand the merge easier. Press the Hibernate/Evidence Ancestor Pane button for that. This is demonstrated by the post-obit screenshots.

Once you have manually merged the changes, select from the context menu of the resource to mark the conflicts as resolved and commit the merge commit via .

10.9. Git reset and Git reflog

The History view allows you lot to reset your electric current branch to a commit. Right-click on a certain commit and select and the reset mode you would similar to use.

ten.10. Finding "invisible" commits with the Reflog view

Commits are not visible in the Git history if they tin can't be reached from a branch or tag. This might happen during a reset, commit amend or rebase operation. Past default, such invisible commits are removed subsequently 2 weeks past the Git system.

The Git Reflog view keeps track of the movements of the Head arrow and the movements of each branch. This view allows y'all to discover a commit over again, eastward.g., if yous used the git reset --hard command to remove certain commits.

ten.11. Selecting individual commits via git ruby-pick

In the History view, you can cerise-pick a commit via the context menu. Crimson-choice allows to move selected changes describes by a commit to another branch. You can also use information technology in combination with a Git reset to perform a simplified interactive rebase.

Lets assume the following state of affairs, in which you would like to remove the "Bad commit" from the history described by the master co-operative.

Yous could start with a hard reset of the branch to origin/main. This will motion the master branch pointer to the commit described by origin/master. The Good and the bad commit are not reachable anymore by the master branch.

To re-utilise the changes by the "Skillful commit", cherry-red-pick the skillful commit.

This results in a history without the bad commit.

10.12. Comparing and replacing files based on the Git history

10.12.1. Comparing files

Eclipse Git allows you to compare a selected file, folder or project with another commit or with the Git index. Use to open the menu. Afterwards select with what you lot want to compare. The HEAD Revision option is depicted in the following screenshot.

10.12.2. Replacing files

The carte entry allows you to replace the current selection with the version contained in the selected commit or the Git index.

11. See Git information line past line (aka git blame)

Eclipse allows to brandish the information which commit and person modify a line. To enable this, right-click on your file and select .

This action is as well available via the line ruler in most editors.

Later on, yous can place the mouse on the left side of the editor. A popup dialog shows the commit data and the change practical by the shown commit.

To ignore whitespace changes in the Git blame annotations in Eclipse, select and select Ignore whitespace changes.

11.ane. Stash via the Git repository view

The git stash command is available in the Git repositories view. Right-click on your Git repository and select Stash Changes.

11.2. Creating patches

To create a patch for a set of changes with Eclipse, select the resources for which you want to create a patch in the Package Explorer view. Now, right click and select .

The resulting file can exist used to get applied to some other Git repository, via . You can besides apply the patch on a system where Git isn't installed at all, i.due east., you don't demand a Git repository to apply a patch.

12. Using Eclipse Git with GitHub

12.1. Clone project

Copy the URL from GitHub and select in Eclipse from the card the

Eclipse fills out most of the fields based on the URL in the clipboard. Enter your user and password to be able to button to GitHub. Alternative you lot can also apply an SSH key. You can configure Eclipse to know your SSH via the preference setting. This setting is depicted in the following screenshot.

12.2. Push changes

Later y'all made changes and committed them to your local repository, you lot can select on the project binder, to push your changes to your GitHub. This requires write access to the GitHub repository.

xiii. Writing good commit messages

xiii.i. Importance of Git commit messages

A commit adds a new version to the repository. This version is described by a commit bulletin.

The commit message describes the changes recorded in a commit. It should help the user to understand the history of the repository.

A commit bulletin should therefore be descriptive and informative without repeating the lawmaking changes.

13.2. Guidelines for useful commit messages

A commit message should accept a header and a body. The header should be less than 50 with a maximum of 72 characters. The torso should wrap its text at 72. The body is separated from the header by an empty line.

This ensures that the commit message is displayed well on the command line or in graphical tools.

The body describes the reason why the change was made. The changes in the file can be reviewed with the help of Git.

The commit message should be in nowadays tense, eastward.m., "Adds amend fault handling" instead of "Added ameliorate fault handling".

The last paragraph can also comprise metadata as key-value pairs. This data is also referred to as the commit message footer.

This metadata can be used to trigger a certain beliefs. For example, the Gerrit lawmaking review arrangement uses the Alter-Id primal followed by a change-id. This inverse id is used to identify to which review the message belongs.

The commit message footer tin likewise have east.g., 'Signed-off-past'. Or information technology may link to a problems tracking organization, e.one thousand., 'Bug: 1234'.

13.iii. Example message

The following can serve as an example for a commit bulletin.

                  Short summary (less than 50 characters)  Detailed explanation, if required, line break at around 72 characters more stuff to describe...  Fixes: problems #8009 Change-Id: I26b5f96ccb7b2293dc9b7a5cba0760294afba9fd                

13.4. Proficient and bad example for a Git history

The post-obit listing shows the output of the git log --oneline command of a Git repository with bad commit messages. The first value in each line is the shortened SHA-1, the second the commit message. This history is not useful.

                  21a8456 update 29f4219 update 016c696 update 29bc541 update 740a130 initial commit                

The adjacent listing shows the history of another Git repository in which better commit messages take been used. This history already gives a good overview about the activities.

                  7455823 Adds search and filter to the model editor tree 9a84a8a Missing DynamicMenuContribution in kid selector 952e014 Fixes spelling error in Toolbar/Add child 71eeea9 Adds option to import model elements from legacy RCP 123672c New Application wizard is missing dependencies 97cdb9a Creates an id for handlers                

The above example also adds the corresponding bug number to the commit message. Some teams (like the Eclipse platform team) use this approach, others prefer to add the problems number to the commit messages.

14. Contributing to EGit - Getting the source lawmaking

This back up is provided by the EGit project via a set of plug-ins (software component).

Eclipse uses the JGit library to perform the Git commands. JGit is a library which implements the Git functionality in Java.

EGit is hosted on git://git.eclipse.org.
