I am a newbie and have just started with drools with documentation:

1). I am at section 3.4 and got the attached exception while I run the maven command:

mvn -Declipse -Ddocumentation clean install -DlocalEclipseDrop=/folder/jboss-drools/local-Eclipse-drop-mirror

2). I am new in the community so i appreciate if some one guide me how to start other than drools documentation so I can start in a right fashion.

I really appreciate anyones's words here.
