<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">I always prefer to create the maven projects from the scratch. You<br>
only need to add the following deps (groupid and artifactid)<br>
<br>
org.drools<br>
drools-api<br>
<br>
org.drools<br>
drools-core<br>
<br>
org.drools<br>
drools-compiler<br>
<br>
You probably need to add the jboss repository as well in order to get<br>
this deps<br>
