Subject Re: Question about GroovyClassLoader, Imoprt, and ContentAssist
Date Wed, 30 Dec 2015 20:52:10 GMT
Thanks for your help Jochen.  I wanted to close the loop on this thread and
state that the problem was that they were not in the correct location
according to the package structure. I also had other problems resulting in
my symptoms, but I got them cleared up.
