Egit User Guide


Getting Started


If you’re new to Git or distributed version control systems generally, then you might want to read Git for Eclipse Users first. More background and details can be found in the on-line book Pro Git.

If there you are coming from CVS, you can find common CVS workflows for Git Platform-releng/Git Workflows.

Basic Tutorial: Adding a project to version control


Identifying yourself

Whenever the history of the repository is changed (technically, whenever a commit is created), Git keeps track of the user who created that commit. The identification consists of a name (typically a person’s name) and an e-mail address. This information is stored in file ~/.gitconfig under dedicated keys.

EGit will ask you for this information when you create your first commit. By default, this dialog is shown only once until you create a new workspace or tick the checkbox “Show initial configuration dialog” on the Git Preference page:


You can also untick “Don’t show this dialog again” if you want to see it again later.

Instead of using this dialog, you can always change this information using the Git configuration:

  • Click Preferences > Team > Git > Configuration
  • Click New Entry and enter the key value pairs and



Setting up the Home Directory on Windows

Add the environment variable HOME to your environment variables.

  1. In Windows 7, type “environment” at the start menu
  2. Select “Edit environment variables for your account”
  3. Click the “New” button.
  4. Enter “HOME” in the name field
  5. Enter “%USERPROFILE%” or some other path in the value field.
  6. Click OK, and OK again. You have just added the Home directory on Windows.

EGit needs this path for looking up the user configuration (.gitconfig). HOME should point to your home directory e.g. C:UsersTomEnsure correct case! E.g. C:users instead of C:Users may cause problems!

If the HOME variable is not defined the home directory will be calculated by concatenating HOMEDRIVE and HOMEPATH.

If both HOME and HOMEDRIVE are not defined HOMESHARE will be used.

EGit shows a warning if HOME is not defined explicitly. Keep in mind that if you set the HOME environment variable while Eclipse is running, you will still see following warning. You will have to restart Eclipse for it to recognize the HOME value.

Pointing out the System wide configuration

If you use Git for Windows as a companion to EGit, make sure EGit knows where Git is installed so it can find the “system wide settings”, e.g. how core.autocrlf is set. Go to the settings and look under Team>Git>Configuration and then the System Settings tab.

If you selected one of the options to use Git from the Command Line Prompt when you installed Git for Windows, then the location of the system wide settings is filled in with a path and everything is fine. If not, use the Browse button to locate where Git is installed, e.g. C:Program Files(x86)Git.

This advice also applies to users of other Git packagings, e.g. Git under Cygwin or TortoiseGit.

Non-Windows users should in theory check this setting, but the system wide settings are usually not used on non-Windows platforms.

Create Repository

  • Create a new Java project HelloWorld. (In this case, the project was built outside of your Eclipse Workspace.)


  • Select the project, click File > Team > Share Project
  • Select repository type Git and click Next


  • To configure the Git repository select the new project HelloWorld


  • Click Create Repository to initialize a new Git repository for the HelloWorld project. If your project already resides in the working tree of an existing Git repository the repository is chosen automatically.


  • Click Finish to close the wizard.
  • The decorator text “[master]” behind the project shows that this project is tracked in a repository on the master branch and the question mark decorators show that the .classpath and .project and the .settings files are not yet under version control


Track Changes

  • Click Team > Add on the project node. (This menu item may read Add to Index on recent versions of Egit)
  • The + decorators show that now the project’s files have been added to version control
  • Mark the “bin” folder as “ignored by Git”, either by right-clicking on it and selecting Team > Ignore or by creating a file .gitignore in the project folder with the following content
  • This excludes the bin folder from Git’s list of tracked files.
  • Add .gitignore to version control (Team > Add):


  • You may have to set your Package Explorer filters in order to see .gitignore displayed in the Package Explorer. To access filters, select the down arrow at right of Package Explorer tab to display View Menu.

  • Select Filters… from the View Menu and you will be presented with the Java Element Filters dialog. Unselect the top entry to display files that begin with . (period) such as .gitignore.


  • Click Team > Commit in the project context menu
  • Enter a commit message explaining your change, the first line (followed by an empty line) will become the short log for this commit. By default the author and committer are taken from the .gitconfig file in your home directory.
  • You may click Add Signed-off-by to add a Signed-off-by: tag.
  • If you are committing the change of another author you may alter the author field to give the name and email address of the author.
  • Click Commit to commit your first change.


  • Note that the decorators of the committed files changed.


Inspect History

  • Click Team > Show in History from the context menu to inspect the history of a resource


  • Create a new Java class and implement it
  • Add it to version control and commit your change
  • Improve your implementation and commit the improved class
  • The resource history should now show 2 commits for this class



  • Click the Compare Mode toggle button in the History View
  • Double click src/ in the Resource list of the History View to open your last committed change in the Compare View

Congratulations, you just have mastered your first project using Git !

GitHub Tutorial

Create Local Repository

Create Repository at GitHub

  • create a new repository at GitHub


On the next screen you can see the URLs you may use to access your fresh new repository:

  • click SSH to choose the SSH protocol. It can be used for read and write access
  • click HTTP to choose the HTTP protocol. It can also be used for read and write access.
  • click Git Read-Only to choose the anonymous git protocol for cloning. It’s the most efficient protocol git supports. Since the git protocol doesn’t support authentication it’s usually used to provide efficient read-only access to public repositories.


Eclipse SSH Configuration

  • Open the Eclipse Preferences and ensure that your SSH2 home is configured correctly (usually this is ~/.ssh) and contains your SSH2 keys


Push Upstream

  • Click Team > Remote > Push… and copy and paste the SSH URL of your new GitHub repository
  • If you are behind a firewall which doesn’t allow SSH traffic use the GitHub HTTPS URL instead and provide your GitHub user and password instead of using the uploaded public SSH key. To store your credentials into the Eclipse secure store click Store in Secure Store.
  • Note: many HTTP proxies are configured to block HTTP URLs containing a user name, since disclosing a user name in an HTTP URL is considered a security risk. In that case remove the username from the HTTP URL and only provide it in the user field. It will be sent as an HTTP header.


  • Click Next and on first connection accept GitHub’s host key.
  • Enter your SSH key’s passphrase and click OK.
  • On the next wizard page click Add all branches spec to map your local branch names 1:1 to the same branch names in the destination repository.


  • Click Next. The push confirmation dialog will show a preview of the changes that will be pushed to the destination repository.


  • Click Finish to confirm that you want to push these changes.
  • The next dialog reports the result of the push operation.


  • Point your browser at your GitHub repository to see that your new repository content has arrived
