If I understand you correctly, this is a Java runtime restriction.
Java classes in the default package can reference any class in a named
package. Other the other hand, classes in a named package cannot
reference any class in a default package. Classes in a default
package can reference other classes in a default package.
Thus, the easiest way normally to deal with this problem is to either
(1) put everything in a named package, including any grails classes/
domain objects/etc or (2) put everything in a default package. I'd
suggest that you go with option 1 because it'll give you fewer problems.
But I'm not sure if that's the question you're asking or if this helps
you. Hopefully, it does. :)
