title: Detect unit test code coverage of a commit
body: <p>Let's say that the language I use is Java and I do a specific commit, is there a way how I can tell the code coverage of a commit or even if it was done? When a user commits to the repository, I want to have multiple statistics about the commit, including unit test coverage on that specific commit. Is this even possible? Are there already such tools out there or do I need to think about something custom?</p>
  
  <p>I am using Git hosted under Gitblit, I alread saw the hook mechanism by Gitblit, thus it is just a matter of how to do this.</p>
