AW: Is there any generic Maven code generator?
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.

Re: Is there any generic Maven code generator?
First, the way to plug extra functionnality into Maven is to write a Maven plugin so I don't think you can find a Maven plugin to be generic enough to perform any kind of task. For you purpose, you can try a Java annotation processor which are supported by the Maven compiler plugin or a combination of the Maven exec plugin (to launch your own generator) and the Maven build helper plugin (to let Maven know that new files have been generated) Regards Jeff On Wed, Feb 27, 2013 at 12:30 PM, christofer.d...@c-ware.de christofer.d...@c-ware.de wrote: I just posted this to Stackoverflow, but after posting I realized, that I should have come here first :-( I am currently working on a project, that makes intense usage of code generation for various purposes.
