Workaround for maven eclipse:eclipse failure

[Marshall Schor]

If you run eclipse:eclipse goal in the root POM project (uimaj), it 
runs, but doesn't do the right things.  It doesn't reliably set up 
linked resources in the .project, and doesn't reliably set up the 
.classpath file with the proper entries for those linked resources.  The 
observed result is that you get compliation failures in Eclipse - saying 
it can't find things that are in the linked jars. 

The fix is to run eclipse:eclipse in the individual projects, not at the 
root project.

Also, beware of running eclipse:clean goal on the root project - it 
erases the .project file because it is "cleaning", and then won't put it 
back (it sees this is a POM project, not a JAR project, and won't put 
.project files in the POM project).

If anyone has any insight on how to get the eclipse:eclipse goal to work 
from the root, that would be nice to hear.
