I would like to get this up and running where it checks if all junit tests pass.

I believe I have tried to contribute to someone who had this up and running.(ex. at the bottom of this ticket of checks passing: zmoazeni/csscss#95)

We'll need a CI server to do this. Travis CI is free for open source projects. If a maintainer wants to create an account and give me access I can set it up.

I have added you as a collaborator,but I think we may want to move this project to a maven or gradle build which sounds like will change our setup a bit. So let me create a new issue and try to get some feedback.
