List of Git repositories available

Please see

Committers new to Git

Before working on a Git repository, please:

   git config --global
   git config --global "John Doe"
  • Note that the above will set this as the default user name and email address to use when writing commits. You can set and password on a per repository basis.
   git config
   git config "John Doe"

This will set the username and email address on just the current git repository.

Git or Gerrit?

All new repositories at now use Gerrit for access, even if the project does not make use of its code review features. Some mature projects are still using Git. To find out what the project uses, please ask the project, or find the repository on repository browser at

When looking at the repositories, those using the Gerrit Code Review tool are identified as such. Please see Gerrit for more on Gerrit Code Review.

Your Git identity at

Your correct Git committer_id identity is at can be found on the Gerrit settings page. Your user ID is the same for SSH Git and Gerrit.

Note that it is NOT the same as your Username (which is essentially your email address), or Email Address.

Your Git password is your site account password as set on

Gerrit maintains its own password for https: Gerrit also maintains its own SSH keys: These passwords and keys are only used for Gerrit and are not interchangeable with the credentials. Gerrit over SSH does not permit password authentication. A public key must be uploaded for Gerrit over SSH.

If your firewall blocks SSH (port 22) and Gerrit SSH (29418) please try the https:// URLs provided by Gerrit.

Connecting, cloning a repo

Please see the list of Git repositories (above).

Committer access:

   git clone ssh://
   git clone 

These services are provided via Gerrit.

Anonymous, read-only access:

   git clone git://
   git clone

Committing and pushing

The wrong way
The right way
Before committing code to your cloned repo, please ensure that your Git environment is properly set. Otherwise, the user ID and/or email address stored in the commit transaction in your repository will not match your committer ID and/or email address of your Eclipse Committer record with the Eclipse Foundation, and your push will fail.

IP process implications of DVCS

Due to our rigorous IP process, the use-case for a DVCS is different than that of other Open Source organizations. For this reason, an update hook is installed and must remain in place on every Git repository to ensure a clean IP provenance.

The Eclipse update hook will examine the Committer entries of an incoming push. All the committer entries must be of committers on the project, or the push will fail. Furthermore, your committer ID, or the committer email address registered with your committer account at the Eclipse Foundation must be present in the Committer Email record. Here are some scenarios to help understand this restriction:

   Scenario 1
   Jane Contributor is Author of code.  Commits to her local repo.
   Jane Contributer pushes (publishes) to a committer's local repo.
   Committer pushes code to will fail.  
     Committer cannot push code to us from a non-committer.

   Scenario 2
   Jane Committer, known as to the Eclipse Foundation,
       is Author of code. Commits to her local repo as
   Jane Committer pushes code to will fail. does not recognize

   Scenario 3
   Jane Committer, on project B, is Author of code for Project A. Commits to her local repo.
   Jane Committer pushes (publishes) to a committer A's local repo.
   Committer A pushes code to will fail.  
     Committer A cannot push code from a committer who is not on their project.

   Scenario 4
   Joe Contributor Authors code. Commits to his local repo.
   Joe Contributor attaches patch to Bugzilla.
   Committer applies patch to his local repo, commits to his local repo.
   Committer pushes code to will succeed.   
     Committer can push their committed code to us, preserving the Author information in the transaction.

   Scenario 5
   Project Team A has 5 committers. All committers commit to local repo.
   Committer pushes code to will succeed.   
     Committer can push their committed code, as well as commits performed by other project members.

Please see Handling Git Contributions for information on how to handle "pull" requests from non-committers.

Creating a new repository

Please file a bug(community -> git) if your project needs a new repository created.


The cGit web view at supports rendering a Markdown, HTML or plaintext file in the root of the repository, in the master branch, as the "About" tab. In the root of the repository, the file names below are searched (in the order listed). Note: case is important. Such as a file name of "README.MD" will not trigger the "About" tab to be displayed, even though though the <url>/about/ will still display the markup.

  • README.mkd
  • readme.mkd
  • README.rst
  • readme.rst
  • README.html
  • readme.html
  • README.htm
  • readme.htm
  • README.txt
  • readme.txt
  • readme
  • INSTALL.mkd
  • install.mkd
  • INSTALL.rst
  • install.rst
  • INSTALL.html
  • install.html
  • INSTALL.htm
  • install.htm
  • INSTALL.txt
  • install.txt
  • install

Permanently deleting code from Git

If you are required to permanently remove code from a Git repository, please open a bug against Community/Git and Webmaster will do this for you.

Setting up ssh keys

Please login to Gerrit ( to manage your public keys for ssh access.

Referencing git repositories on the wiki

To include a reference to your Git repository on your wiki page, you can use the Git Link Template. This links to the web interface where readers can get an overview of the repository, browse the source code, and see some commit stats. Here is an example:

org.eclipse.ecf.git (browse, stats, fork on OrionHub)

You don't need Git to get code from repository

As mentioned in bug 329841 you can use the cGit web interface to get code, if you just need the code, and do not need to clone the repository, say to prepare patches or commit changes back in to the main repository.

  • This is useful for things like checking out test scripts, say to a hudson slave, there you just need the files to

start a larger test process, such as using Ant's get task to get a URL such as 
  • It can also be useful to refer to a single file for (temporary) reference or review, such as

Gerrit Code Review

If you want to add code review to your Git tool box then see Gerrit.

Errors in Cloning

If your project has requested HTTPS push access, and your are trying to clone(anonymously(via HTTP or GIT)) and receiving 'Corrupted object' warnings:

  • Try to commit a change via ssh(or have another committer on your project do so)
  • Ask your rel-eng to check the permissions on the object in the repo ( should be at least 444 )

If the ssh commit works, and the permissions are not ok then either file a bug, or send a note to Webmaster asking to have the default mask on your git repo repaired. See bug 363599 for details.


The following resources are recommended reading for anyone new to Git or patch-based distributed version control systems in general. Feel free to add links here to reading that you found to be useful.

Recommended Practices

  • Provide a description for your Git repository by editing the description file in the repository root. This description is used in a couple of different places to help the community understand the purpose of the repository. Keep the description concise (e.g. one line of prose).
  • Provide a CONTRIBUTING file in the root of your Git repository. GitHub, for example, encourages this convention to help members of the community understand how to contribute to the project.
    • TODO provide an example of this
    • Note that an Eclipse project cannot simply accept a Git pull request. Before a pull request can be accepted, the contributor must have agreed to the Eclipse Terms of Use. A contributor who has an Eclipse account implicitly makes this sort of agreement.
    • Please see Handling Git Contributions for further information.
