HR integration review request: 225181 - Error badges forces rescan of Grails project

Description:
http://netbeans.org/bugzilla/show_bug.cgi?id=225181


The groovy error badges forces rescan of Grails project.
The Grails project is configured as a single compilation unit, when a one root
of the peer roots is compiled the files from other peer roots with error needs
to be checked for possible error correction. It triggers a new non needed scan just
after the initial scan.

Impact assessment: The grails root is scanned twice. As the groovy parsing is rather slow it slows down IDE
start.

Risk assessment: low
