When attaching test dependies with Maven, you specify the
Then the name-tests.jar artifact si downloaded.
But as for source, maven-source-plugin generates a
name-test-sources.jar file and not a name-tests-sources.jar. And Idea
90.94 is looking for name-tests-sources.jar chich doesn't exist.
Seems it's an old bug from my search on google but I've never tried to
import such artifcats on IDEA before.
