Subject AW: Is there any generic Maven code generator?
Date Fri, 01 Mar 2013 17:32:48 GMT
Well I guess, I will eventually whip up such a plugin myself, cause I really need to cleanup
quite a code-generation mess. 
Eventually based upon the GraniteDS libs, as does the Flexmojos plugin.

The following is not going to really help you, but I just wanted to point out that a plugin
was recently initiated at mojo (still in the sandbox) dedicated to templating (called templating-maven-plugin).
It's currently only supporting Maven sources filtering, but the plan is to support different
templating engines like velocity or mustache for example.

Cheers
