xmlbeans plugin updated... need a clean build.

[David Jencks]

I've updated the xmlbeans plugin to not generate classes that are 
already  generated in another module.   To avoid problems you should do 
a clean build.

I suggest
maven clean;maven plugins;maven
I had some problems convincing the build system that the new plugin 
version was actually there and should be used.  If you get class cast 
exceptions or similar errors related to generated classes try the above 
a second time.

thanks
