This happens in the current trunk. I think the bug was introduced with the fix for
IvyDe now seems to merge the configurations from resolve and "retrieve after resolve" event if "retrieve after resolve" is not enabled.
I've marked this blocker since a central and once working feature does no longer work.
How to Reproduce:
Add a IvyDe Classpath Container for an ivy.xml with multiple configurations but set Ivy to Resolve only one of them.
Leave the "Retrieve after resolve" Option unchecked.
IvyDe will resolve all configurations.
Activate Retrieve after resolve and enter the correct configuration a second time. You willl endup with resolved artifacst but IvyDe will now only resolve the wanted confiugration.
