Elliotte Rusty Harold commented on MDEP-737:
--------------------------------------------

I suspect what's happening here is that the dependency plugin is simply 
following the usual maven dependency mediation algorithm in which the test 
dependency comes ahead of the compile dependency. Therefore it picks the test 
dependency.

> dependency:list sets compile scope deps as test scope

> test-scope?
