java - Ensure minimal coverage on new Subversion commits

Question

We have a massive project with almost no unit tests at all. I would like to ensure from now on that the developers commit new features (or bugs!) without minimal coverage for corresponding unit tests.

What are some ways to enforce this?

We use many tools, so perhaps I can use a plugin (jira, greenhopper, fisheye, sonar, hudson). I was also thinking perhaps a Subversion pre-commit hook, the Commit Acceptance Plugin for jira, or something equivalent.

Thoughts?

Sonar (wonderful tool by the way) with Build breaker plugin can break your Hudson build when some metrics don't meet specified rules. You can setup such a rule in Sonar that would trigger an alert (eventually causing the build to fail) when the coverage is below given point. The only drawback is that you probably want the coverage to grow, so you must remember to increase the alert level every day to the current value.
