OK, I get much the same stack trace doing the same as you.<br><br>I think the recommendation is to normally get the whole source tree if performing maven functions(?!?!?).<br><br>I don&#39;t know what the expectation is (from the Drools team) regarding running maven functions against sub-projects (like examples). If the expectation is to be able to do as you have tried it might need some invesitgation. Otherwise you can create a new Java Project, import the source and fix dependancies manually (if you don&#39;t want to run maven against the entire source tree).<br>
<br>If you are new to drools I do recommend spending a little time to get the examples working; they are worth the effort.<br><br>Anyway, to answer your question the subversion URL is <a href="http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk">http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk</a><br>
