We accept PRs via github. The developer mailing list is the main channel of communication for contributors. There are some guidelines which will make applying PRs easier for us:

  • No tabs! Please use spaces for indentation.
  • Respect the code style.
  • Create minimal diffs - disable on save actions like reformat source code or organize imports. If you feel the source code should be reformatted create a separate PR for this change.
  • Provide JUnit tests for your changes and make sure your changes don't break any existing tests by running mvn clean test.

If you plan to contribute on a regular basis, please consider filing a contributor license agreement. You can learn more about contributing via GitHub in our contribution guidelines.
