How to build and run the Drools and Guvnor Beta3 Demo

After the release of the Drools and Guvnor beta3 video see here, I’m being asked how people can build and run it themselves. Luckily it’s very easy, so here are some quick instructions 🙂

  • Make sure you set your MAVEN_OPTS:
    • MAVEN_OPTS=”-Xms512m -Xmx1024m -XX:MaxPermSize=128m”
  • Git clone:
  • From clone root, built the main application:
    • mvn clean install -DskipTests
  • Change to the WAR module:
    • cd drools-wb/drools-wb-distribution-wars
  • Build the WAR
    • mvn clean install -DskipTests
    • Builds Tomcat and JBoss AS WARs, with the firefox profile.
      • WAR only works with Firefox, but quick to compile, for testing.
  • Download unzip and start JBoss AS7.1
    • ./
    • Once started, don’t forget to create a management user with
  • Install the WAR via the AS web console
    • Find the WAR and upload it, AS automatically installs it
    • drools-workbench-6.0.0-SNAPSHOT-jboss-as7.0.war
  • Go to URL and login
    • http://localhost:8080/drools-workbench-6.0.0-SNAPSHOT-jboss-as7.0
    • login/pass admin/admin
    • Must use fireFox, as maven build defaults to reduced number of profile sets, for fast building. 
      • Use -PfullProfile with mvn install, to build all profiles, with longer build times.
  • There is a sample repo, but mostly has rubbish in it, stick to the uberfire playground.
Things to notice, or try:
  • Maven POM editor, when the file explorer is inside a maven project
  • As per my video, try building and installing the poject, and viewing in the maven manager
  • Clone some external projects, see if you can build and deploy them
  • Have a play with some of the custom editors, especially the guided editors and decision tables.
