EGit is the Git integration for the Eclipse IDE, see http://eclipse.org/egit
This Tutorial describes the basic use cases for EGit. It requires only
some basic knowledge about the Git processes. Please help us to keep

tutorial is available now as a downloadable PDF
Installing EGit in Eclipse
EGit is already included in the Eclipse Juno Release, so you do not
need to install it. If you use an older version of Eclipse, open the
Eclipse Wizard to install new software Help => Install New Software
. Insert http://download.eclipse.org/egit/updates
after Work with:
and hit Return. Select Eclipse EGit as a child from Eclipse Team Git
Provider. You don’t have to install any other plugins. Click Next
and confirm your selection in the following window by pressing Next
to start the installation. After the installation has finished restart Eclipse.
Every commit in EGit will include the user’s name and his email-address. These attributes can be set in the Preferences-window Window => Preferences. Navigate to Team => Git => Configuration and hit the New Entry… Button. Enter user.name as Key and your name as Value and confirm. Repeat this procedure with user.email and your email address and click OK in the Preferences window. The username and email should be the same you use for your Git account, ie. your GitHub account.
Creating Local Repositories
One major advantage of Git compared to SVN or CVS is that you can
easily create local repositories, even before you share them with other
people. In this way, you can version your work locally. First, you have
to create a project in Eclipse that you want to share via your local
repository. For later purposes it would be useful to add some files,
e.g. a Java class to your project.
After you have created your project, select the context menu by right clicking it and navigate to Team => Share Project… . Select Git as the repository type and hit Next. In the following window select your project, hit the Create Repository-button and click Finish.
The newly created repository will be empty, although the project is
assigned to it. (Note the changed icons: the project node will have a
repository icon, the child nodes will have an icon with a question mark,
ignored files, e.g. the bin directory, won’t have any icons at all.)
Before you can commit the files to your repository, you need to add
them. Simply right click the shared project’s node and navigate to Team => Add.
After this operation, the question mark should change to a plus symbol.
To set certain folders or files to be ignored by Git, e.g. the bin
folder, right click them and select Navigate => Ignore. The ignored items will be stored in a file called gitignore,
which you should add to the repository. The last thing to do is commit
the project by right clicking the project node and selecting Team => Commit…
from the context menu. In the Commit wizard, all files should be
selected automatically. Enter a commit message (the first line should be
headline-like, as it will appear in the history view) and hit the Commit button. If the commit was successful, the plus symbols will have turned into repository icons.
Now you can start to modify files in your project. To save changes
made in your workspace to your repository, you will have to commit them.
After changing files in your project, a “>” sign will appear right
after the icon, telling you the status of these files is dirty. Any
parent folder of this file will be marked as dirty as well.
If you want to commit the changes to your repository, right click the project (or the files you want to commit) and select Team => Commit…
. This will open a new window, allowing you to select the files you
want to commit. Before you can commit the files, you will have to enter a
commit message in the upper textbox. After you’re done, click Commit to commit the selected files to your repository.
Note that the status of the changed file is Mod., not staged. By staging the files before you commit (see the section “Additional Information”), you can change the status to Modified (and the dirty sign to a staged icon).
If you later realize that your previous commit was incomplete (e.g.
you forgot to commit a file) or your commit message was wrong, you might
want to use Amend previous commit. This will merge the current
commit and the previous commit into one, so you don’t have to perform
an extra commit (and maybe cause confusion). However, this should only
be used if the previous commit hasn’t already been published to a shared
Another option is Show untracked files. By checking this checkbox, new files you created but did not add yet, will be available for you to select in the Commit window.
To add a new file to the repository, you will have to create it in
your shared project first. The new file will, again, appear with a
Right click it and navigate to Team => Add. The question
mark will turn into a plus symbol and the file will be tracked by Git,
but it is not yet committed. All of the file’s parent folders should now
have a symbol that looks like an asterisk indicating that it is
‘staged’. In the next commit, the file will be added to the repository
and the plus symbol will turn into a repository icon. The repository
icons of all the file’s parents (packages/project…) will turn into
staged icons. EGit also allows selecting untracked files to be added in
the commit dialog if you turn on the option “Show untracked files”. In
this case, they will be added and committed at the same time.

If you want to revert any changes, there are two options. You can
compare each file you want to revert with the HEAD revision (or the
index, more in the section “index”) and undo some or all changes done.
Second, you can hard reset your project, causing any changes in the
working directory to be reverted.
Revert via Compare
Right click the file you want to revert and select Compare With => HEAD Revision.
This will open a comparison with the HEAD Revision, highlighting any
changes done. If you want to completely revert your file, hit the Copy All Non-Conflicting Changes from Right to Left-button in the Java Source Compare toolbar. If you only want to revert several lines, select each line individually and hit the Copy Current Change from Right to Left
button (in the toolbar) for each line. To complete the Revert
operation, you will have to save either the comparison or your local
copy of the file.
Revert via Reset
To reset all changes made to your project, right click the project node and navigate to Team => Reset… . Select the branch you want to reset to (if you haven’t created any other branches, there will be just one) and choose Hard as
a reset type. By confirming this operation, all changes will be reset
to this branch’s last commit, including all changes done in the
workspace (and index, more on that in the section “index”). Be careful
with this option as all changes in your workspace will be lost.
For this and some of the following sections (especially Fetch/Push), you might want to use https://github.com
to create your own remote repository. Public repositories are free at
GitHub and performing the actions might help you gain some insights.
In order to checkout a remote project, you will have to clone its repository first. Open the Eclipse Import wizard (e.g. File => Import), select Git => Projects from Git and click Next.
Select “URI” and click next. Now you will have to enter the
repository’s location and connection data. Entering the URI will
automatically fill some fields. Complete any other required fields and
hit Next. If you use GitHub, you can copy the URI from the web page.
Select all branches you wish to clone and hit Next again.
Hit the Clone… button to open another wizard for cloning Git repositories.
Choose a local directory to save this repository in.
To import the projects, select the cloned repository and hit Next. Select Import Existing Projects and hit Next.
Please note that there needs to be existing projects in your
repository, and if you use your own repository it might be empty, so you
have to create an initial branch. In the following window, select all
projects you want to import and click Finish. The projects
should now appear in the Navigator/Package Explorer. (Note the
repository symbol in the icons indicating that the projects are already
To create a new branch in your repository, right click a shared project and navigate to Team => Switch to => New Branch… from the context menu. Select the branch you want to create a new branch from, hit New branch and enter a name for the new branch.
The new branch should appear in the branch selection window. If you
would like to checkout the newly created branch, select it and click Checkout.
To merge one branch into another, you will have to checkout the
branch you want to merge with. Right click the project node and navigate
to Team => Merge… . Select any branch (other than the checked out branch) and hit Merge.
The merge will execute and a window will pop-up with the results. The possible results are Already-up-to-date, Fast-forward, Merged, Conflicting, Failed
. A Conflicting
result (see image below) will leave the merge process incomplete. You will have to resolve the conflicts (see next section). A Failed
result may occur when there are already conflicting changes in the working directory.
If your merge resulted in conflicts (note the red symbols on the file
icons), you will have to resolve these manually. Open the conflicting
files and scroll to the conflicting changes marked with
After you are finished the manual part of the merge, you will have to tell Git that the conflicts are resolved. To do so, Add the files and Commit to complete your merge.
Fetch and Pull
When cloning remote repositories, Git creates copies of the branches as local branches and as remote branches. A Fetch operation will update the remote branches only. To update your local branches as well, you will have to perform a Merge operation after fetching. The operation Pull combines Fetch and Merge. To perform a Fetch, select Team => Fetch From…
from the project’s context menu. Enter the repository you want to fetch
branches from. (If you cloned this repository, the remote branch will
be selected as default.) In the following window you will have to select
what you want to fetch. As default, all branches are selected. The
result of the Fetch-operation will be shown in a final confirmation window. Follow the same steps to apply a Pull.
Local changes made to your local branches can be pushed to remote
repositories causing a merge from your branches into the branches of the
remote repository (X pulls from Y is the same as Y pushes to X). The Push wizard is pretty much the same as the Fetch wizard. First, right click the project node and navigate to Team=> Push… . Enter the repository you want to push your branches to (the default for this will be the same as the Fetch default if you didn’t configure a Push default) and hit Next. Choose the branches you want to push or click Add all branches spec
if you want to push all branches. You can also select branches you want
to delete from the remote repository. If you are done hit Finish. A final window will show the results of the Push.
Comparisons between your workspace and the local repository or between the current branch and others and are done via the Synchronize operation.
If you right click Team => Sychronize Workspace, your local
workspace will be compared with the current branch showing uncommitted
changes. If you select Team => Advanced => Synchronize… .
, you can select other branches to compare your current branch with. In
this case you can also include local uncommitted changes.
To compare the branches you may want to switch to the Synchronizing
perspective, where you can get a more detailed view of several changes.
Here is an example of a Synchronize operation in the Synchronizing perspective:
To show any shared file’s history, right click it and select Team => Show in History.
This will open the History View, giving an overview of the commits and
allowing you to perform several actions (compare, creating
branches/tags, reset…). Every commit you select comes up with a revision
comment and revision details. The revision comment (bottom left corner)
includes parents, children, commit message and changes whereas the
revision details (bottom right corner) name the changed files and the
actions performed upon them (A=ADD, M=MODIFY, D=DELETE). Selecting a
file in the revision details will scroll the revision comment to the
changes to that file.
Any patch can only include one commit that is from a parent to its
child. To create a patch you have to open the History View first (see
previous section). Right click a commit you want to create a patch for
(this must be a child with exactly one parent) and select Create Patch….
Select either Clipboard or File and hit Next and click Finish. The resulting patch can be applied to the parent commit via Team => Apply Patch….
The repository view is useful when working with branches/tags and
executing operations on them, as well as handling remote repositories
and getting an overview of all your repositories. To open this view,
select Team => Show in Repositories View from any file’s context menu.
: The repository treats these files as if they were non-existent (e.g. the bin-directory by default). Add a .gitignore file or Team => Ignore
to ignore a file.
: Any file known, but not yet recorded. To track a file, add it or select the Show untracked files
-option in the commit-wizard and commit it directly.
: Any file known to and recorded by the repository.
: Any file known to the repository, but not yet committed. Perform a Commit
to change this file’s status to tracked.
: Any file that should be removed from the repository. For this icon to appear Team => Untrack
has to be performed. By deleting the file from the workspace, the file
will disappear (and therefore no icon will appear). However, it will
still be removed from the repository with the next commit.
: Any tracked file with changes that have not yet been added to the index.
: Any tracked file with changes that are already included in the index.
Any tracked file with changes, where some changes are already included in the index, and others that are not yet added.
: Any file where the merge result caused a conflict. Resolve the conflicts and perform an Add
operation to change this file’s status.
: Any modifications won’t be checked by Git. This option can be activated via Team => Assume unchanged
. However, it can only be turned off via the command line. Performing a Reset
operation resets this status as well.
The index, sometimes referred to as staging area, is an area between
the working directory and the repository. Any change made to any file
will change this file’s status to dirty (see above). Any dirty file can be added to the index with an Add operation. The file’s status changes to staged.
You can compare files to the index and reset the index without
resetting the workspace. In the original Git, files had to be added to
the index before performing a Commit operation. This is not necessary in EGit, as Team => Commit allows you to commit unstaged changes.
You can reset your current branch to any other branch, tag or commit
you want. Right click any commit in the History View and select Reset. There are three options available:
The current branch’s tip will point to this branch/tag/commit.
Changes in the index and working directory, however, won’t be reset.
Same as a soft reset, only that the current index will be replaced by
the selected branch/tag/commit’s index. The working directory stays
All changes will be reverted to the selected branch/tag/commit.
Uncommitted changes will be lost, therefore this operation has to be
