A while back I downloaded, installed and configured
eclipse-jee-europa-fall2. I must have added PDE to it. But to my
surprise the source for the base classes of my plugin are not
available. I guess I should have downloaded the RCP version of eclipse
and added J2EE to it? How to get the source for eg
org.eclipse.core.resources.IncrementalProjectBuilder into my
environment? Seems like this ought to come with PDE right?
