Description

When trying to build/run some tests in the IDE, IntelliJ is reporting the following compilation failure:

/XXX/flink/flink-clients/src/test/java/org/apache/flink/client/testjar/TestUserClassLoaderJob.java:33:38
java: cannot find symbol
  symbol:   class TestUserClassLoaderJobLib
  location: class org.apache.flink.client.testjar.TestUserClassLoaderJob

A workaround seems to be to:

1. right click on flink-clients
2. Rebuild module (flink-clients)

The issue is probably related to the comment from the flink-clients/pom.xml file:

			<!--Remove the external jar test code from the test-classes directory since it mustn't be in the
			classpath when running the tests to actually test whether the user code class loader
			is properly used.-->
