We seem to be having troubles with heap space and the plugin.

FATAL: Java heap space
java.lang.OutOfMemoryError: Java heap space

Crap itself seems to be finishing, but the plugin is doing something to use up
heap space. It's intermittent, of course. We can increase heap size for the
build process, but I thought I'd ask here for alternative ideas.

thanks
