Hi, The Apache Flink project is using Maven for dependency management. We shade Google's Guava away (to org.apache.flink.shaded.com.google.commons) to avoid conflicts with user guava versions.
Building Flink with Maven 3.2.5 will create a valid fat-jar without guava. However, Maven 3.3.9 (and other 3.3.x versions) are including guava in the com/google/commons namespace. Interestingly, doing only a "clean install" in the "flink-dist" package after a build of the parent pom results in a correct "flink-dist" fat jar. I'm wondering which behavior of Maven is correct 3.2 or 3.3 ? I have the feeling that 3.3 is behaving incorrectly because the dependency:tree of "flink-dist" does not contain Guava. Maybe a "clean install" on the parent pom with Maven 3.3 is not respecting the dependency-reduced poms created by the other modules? Regards, Robert
