I worked around that by commenting out the test testDoLoopScheduledActivation in drools-core/src/test/java/org/drools/reteoo/SchedulerTest.java. I tried again. It ran for quite a while but failed with this error: [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] An Ant BuildException has occured: Directory does not exist:/home/lmulcahy/java/drools/src/drools-eclipse/org.drools.eclipse/lib Workaround: mkdir drools-eclipse/org.drools.eclipse/lib Also somewhere in there I got an out of memory: permgen exception. Fixed with set MAVEN_OPTS=-XX:MaxPermSize=256m -Xmx1024m With that, the build was able to run to completion.
