As the JaCoCo plugin I used so far is marked as deprecated I switched to the Coverage plugin. And it seems to work fine. At least for some smaller projects. But for a larger one the build time went up from 11 minutes to 4h 30m! But only if I include the source code. If I set "Source Code Retention Strategy" to "Never store source code" I am back to 11 or 12 minutes. Any thoughts on that?
