+           This plugin forces the generation of jar containing streaming test classes,
            so that the tests classes of external modules can use them. The two execution profiles
            are necessary - first one for 'mvn package', second one for 'mvn test-compile'. Ideally,
            'mvn compile' should not compile test classes and therefore should not need this.
