Hi Im new to drools. Im trying to get gwt-console work with jboss server. So I downloaded the gwt-console code from svn ( http://anonsvn.jboss.org/repos/soag/bpm-console/trunk) and when I try excecute mvn install command from trunk it gives me following error. I tried googling but I couldn't find a way to get rid of this error. And also in forums they say that we need to change pom.xml to use drools as defult profile. Where I can change it? Thanks alot if some one can help me. Im trying to start learning jboss drools and i have already installed jboss and Guvnor. shanika@shanika-laptop:~/JBossDrools/gwtConsole$ mvn -version Maven version: 2.0.9 Java version: 1.6.0_0 OS name: "linux" version: "2.6.28-18-generic" arch: "i386" Family: "unix" shanika@shanika-laptop:~/JBossDrools/gwtConsole$ mvn install [INFO] Scanning for projects...
