It is not possible to add or release a maven2 project using the git scm when the project is on a branch. There appears to be multiple reasons for this:
- The maven-scm version bundled with continuum is old and doesn't include git providers with sufficiently complete git support.
- Git SCM URLs don't include sufficient information to identify the branch.
- Continuum-release's UpdateWorkingCopyPhase doesn't properly update the working (it always uses master rather than the current branch)
