We accept Pull Requests via GitHub. Thedeveloper 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 existing code style for each file.
• 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 runningmvn.
• Before you pushing a PR, runmvn (by itself), this runs the default goal, which contains all build checks.
• To see the code coverage report, regardless of coverage failures, runmvn clean site -Dcommons.jacoco.haltOnFailure=false -Pjacoco
