Github user tillrohrmann commented on the pull request: https://github.com/apache/flink/pull/1698#issuecomment-191806709 I think, this does not solve the problem of the test. The test case `ScalaShellITCase.testSubmissionOfExternalLibrary` expects that `flink-ml` has been packaged, because it looks in `../flink-libraries/flink-ml/target/` for the jar file. However, this is not guaranteed by introducing an dependency on `flink-ml` and `flink-dist`. Adding the dependency could also mean that it is simply downloaded from maven and stored in the local maven repository from where it is referenced. What could help, though, is to find out the location of `flink-ml` and `flink-dist` from the provided classpath.
