Unable to get SonarCloud to recognise generated jacoco xml coverage


I am somewhat new with continuous systems and have been struggling to get Sonar to recognize JaCoCo’s coverage analysis.

From what I can tell, this github action workflow in this project successfully builds an xml file to /target/site/jacoco/jacoco.xml, as I am led to believe from this log.

Unfortunately, no matter what I do, I can’t seem to get sonar to detect jacoco (and its analysis of our unit tests). Our current prototype’s coverage is 56% which, while far from great, is more than the 0% I have been able to get sonar to show.

I’ve tried setting sonar.coverage.jacoco.xmlReportPaths to a variety of values (including leaving it blank), yet have not yet been able to get any results.

Hey there!

The logs in your action say that no tests ran :zipper_mouth_face:

Tests run: 0, Failures: 0, Errors: 0, Skipped: 0

So that’s probably the root cause of this.

Thanks for pointing that out! I was able to discover a missing dependency that was causing the problem!
