Thanks a lot, Alan! The surprise for me was that --patch-module is used for source folders, too. I thought it was only for binaries. But I noted I also have to add "--add-modules=junit" or the "--add-reads m=junit" will give an error that module junit cannot be found. So the command has to be: javac -d target/test-classes --patch-module m=src/test/java --module-path target/classes:junit-4.8.2.jar --add-modules=junit --add-reads m=junit src/test/java/p1/P1Test.java I’m not sure if that is a bug or a feature. BTW, I noted that "javac -help" doesn’t mention --patch-module and --add-reads at all (only --add-modules)
