Hi, indeed JaCoCo processes all class files and recursively all zip files by default. So if you’re *.mkp is in ZIP format it will be processed by JaCoCo.
The problem can probably be fixed by specifying an includes pattern **/*.class for the report-aggregate goal: https://www.jacoco.org/jacoco/trunk/doc/report-aggregate-mojo.html#includes Regards, -marc > On 17.
