I try to build Jacoco in order to check how the "report-aggregate" sample works.
Thus I downloaded todays source zip and run the build with the command "mvn clean install". My environment: Windows 11, Java 17.0.16, Maven 3.9.11.
The build fails here:

Is this something that is worth a bug report?

Hi Wolfgang,
I cannot explain the specific failure you see. But with Java 17 we use the following command line arguments:
mvn clean verify -Djdk.version=17 -Dbytecode.version=17
See build documentation: https://www.jacoco.org/jacoco/trunk/doc/build.html
Best regards,
-marc

JaCoCo is maintained by a very small group of volunteers
and AFAIK none of them is using Windows
and AFAIK none of them is using Windows
unfortunately in our CI on Windows org.jacoco.core.test.validation.scala module is also excluded from build
Your problem according to the stacktrace seems to originate from scala-maven-plugin
And seems that upgrade of it helps - https://github.com/jacoco/jacoco/pull/1957
So you can either
try to build from the above PR/branch
try to build from the above PR/branch
or apply the same upgrade in your working copy
or exclude module org.jacoco.core.test.validation.scala from build
mvnw clean package -pl '!org.jacoco.core.test.validation.scala'
mvnw clean package -pl '!org.jacoco.core.test.validation.scala'
