I'm still confused why these things are to be mixed together and not just separated out so the IDE's classpath/scopes
matches the compile scopes (seems like neither Eclipse, intellij nor netbeans would be able to mimic
what is being attempted in Gradle?)

Anyway, eclipse can have multiple output directories, but only one classpath so you would probably
be able to get things to compile or code complete in eclipse that won't compile in the Gradle build but if that is not a concern
then things should be fine.

btw. Its really a shame core will no longer be easy to import into Eclipse.
It's back to the "everyone attempts their best in creating an eclipse config" from the old Ant days ;(
