Debugging output only for a subproject in a reactor run

Hi all,

I have problems with a very specific plugin in our build and want to
enable debugging output only for the subproject in our overall build
setup. The commandline option -X enables debugging for the complete
execution, and I fear this would create too much output and might fail
the build due to memory problems... Now, is there a way to change the
logger during the build to enable debugging just for this one project?
(plugins running in pre and post phases to enable/disable that?)

Thanks,
Christia
