I seem to have the same issue.
Seeing the “s” in xmlReportPaths, I assumed that I could supply several paths like this:
property 'sonar.coverage.jacoco.xmlReportPaths', '../../folder1/target/site/jacoco-aggregate/jacoco.xml,../../folder2/target/site/jacoco/jacoco.xml'
But in my logs, I see this, it seems that the 2nd one is imported but not the first one.
