This is a known issue with the eclipse maven mojo http://jira.codehaus.org/browse/MECLIPSE-37
The JIRA also describes a workaround, add the generated tests directory in the eclipse config with a pom change, which I think would be better then trying to move the phase where test code is generated. So please file a JIRA for it and we can discuss the proper fix in context of that JIRA. --Bobby Evans On 9/20/11 8:35 AM, "Alejandro Abdelnur" <t...@cloudera.com> wrote: Laxman, This is not an incorrect usage of maven phases, those generated Java classes are test classes, thus is generation in the 'generate-test-sources' phase. The problem seem to be that eclipse does not recognize the target/generated-test-source/java directory as a source directory (for example, IntelliJ does). One thing we could try (not 100% correct but it would simplify the life of eclipse developers) is -as you suggest- to change the phase to 'generate-sources'. But the generated sources and corresponding compiled classes there must be compiled and used for testing, the classes should end up in the target/test-classes directory. If the above is doable it should a nice workaround. Please open a JIRA to follow up with this. Note that is not only in common that code is generated, but in mapreduce as well. And there are different things being generated, avro, protobuf, etc. Thanks.
