I was able to get it to work, both as separate groovy and java
directories and as one directory ( basically a groovy directory with
mixed ).
It is interesting how complex this task was. It would appear as if the
Groovy community should have figured this out by now.
I finally ( after 10 hours ) was able to get it to work, using only ANT.
The question is why Gmaven, GMaven2 Eclipse maven, and what not is even
mentioned when it is as simple as an ANT task.
In constract, pulling in Scala and Kotlin ( during the process which I
gave up on Groovy ) took seconds.
Relying on the Eclipse compiler is not a good thing as it has a history
of breaking and not being up to date with any other compiler that one
might wish to use.
The solution ( note that I change some other things as well, like I
don't use src/main/java but just src ):

Subject: Re: Integrating Groovy with a Java EE application and Maven
I have gotten a bit further in my research and came up with this
sample project which uses ant to compile the groovy classes but I
can't get them to compile together.
To be able to have cyclic dependencies between Java and Groovy files.
Here is a standalone isolated maven project that contains everything:
