All, I wish to be part of the JBoss community and contribute in whatever ways I can. So, i started out by checking out the source from SVN (  http://anonsvn.jboss.org/repos/jbossas/trunk/build http://anonsvn.jboss.org/repos/jbossas/trunk/build ) and following the readme, executed build.bat. Initially the build failed with outOfMemory errors but then i got around them by setting the MAVEN_OPTS to use Xmx1024m. so, now it is not throwing OutOfMemory. 

But i'm getting this error while executing JBoss Application Server Build. It always fails with the error 

[ERROR] Failed to execute goal org.codehaus.mojo:license-maven-plugin:1.0-alpha-1-2-jbossorg:download-licenses (default) on project jboss-as-build: Unable to parse license summary output file. NullPointerException -> [Help 1]

I'm on Win 7, 32bit, 4GB i7 machine. And my source version is 110803, and i'm on the trunk of jboss. 


I have been trying to find relevant information on this but so far no fruit. Any light to help me out is appreciated. 

P.S: If there are links available to help out a new member to the community in explaining the architecture as well as the standards, frequently faced issues and such, please point me to their direction.
