Lincoln Baxter III commented on JBIDE-14396:
--------------------------------------------

Hmmm... sorry for the late reply. Had a busy day yesterday.

Question about unknown classifiers. If it's a JAR, why would you not add all the classes? Why just a subset? In fact - why do anything differently from the Eclipse classpath, or Maven?

It does not make sense to me to require a separate plugin just to configure this. If anything, I would think that you would use a separate plugin to instead deviate from this - what I would call - expected behavior.

Maybe I don't understand the other scenarios, but why would you want anything else?

> Example project: https://github.com/forge/core/tree/M2ECLIPSE-BUG
> Steps to reproduce:
> * Import all modules into the workspace. 
> * Select "aesh-tests" project.
> * Run as -> JUnit Test
> You should see the test fail to launch because of the following Class not found exception:

> This can be solved by manually adding required projects in the workspace as classpath dependencies of the JUnit launch configured for the project being tested, but this is obviously not right, and should be configured automatically by the M2E integration.
