Hello, I've created a build job for the junit5 branch [1]. It's a copy of the maven-surefire job with the only difference that it does not publish build artifacts to the snapshots repository. It maybe possible to configure this more elegantly by using the Jenkins Pipeline Plugin, but I don't know how. I think this is good enough for a start.
