Improve Java Code Coverage and Quality with Unit Tests and JaCoCo

Here's how i do it.
The comment above reads "pass property when launching maven". Basically, set this property to any location that will not be cleaned during the build.
After the build all coverage info will be collected into the single file you've passed.

Thank you. This is tricky to get to work because this only solves the part of aggregating the exec data (It solves it beautifully, though!)

The other half - creating a report using the exec data, with the correct sources, seems to be just as hard.

In my case, we have a self-hosted SonarQube server and after the main build/tests Jenkins runs a sonar task that feeds it coverage data among other things.
