Re: [rules-users] NPE after rule consequence executes

I noticed one error in the build: ------------------------------------------------------------------------------- Test set: org.drools.integrationtests.DynamicRulesTest ------------------------------------------------------------------------------- Tests run: 16, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 2.5 sec <<< FAILURE! testDynamicFunction(org.drools.integrationtests.DynamicRulesTest) Time elapsed: 0.062 sec <<< ERROR! java.lang.NoClassDefFoundError: org/drools/test/AddFive at org.drools.test.Rule_global_rule_test_0.consequence(Rule_global_rule_test_0.java:9) at org.drools.test.Rule_global_rule_test_0ConsequenceInvoker.evaluate(Rule_global_rule_test_0ConsequenceInvoker.java:20) at org.drools.common.DefaultAgenda.fireActivation(DefaultAgenda.java:550) at org.drools.common.DefaultAgenda.fireNextItem(DefaultAgenda.java:514) at org.drools.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:477) at org.drools.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:439) at org.drools.integrationtests.DynamicRulesTest.testDynamicFunction(DynamicRulesTest.java:311) Scott Reed's message received 4/9/2008 5:25 PM: I built it but can only find the core jar file, nothing for the compiler. With just the core jar replaced, I still get the NPE. Edson Tirelli's message received 4/9/2008 2:24 PM: Nope, only source code. Problem is 4.0.x will be released as 4.0.7, and if your specific problem is fixed and you are not able to test before the release, it will have to wait 4.0.8. All you need to build drools is java, maven and ant. Can you set this up? []s Edson 2008/4/9 Scott Reed <sreed(a)avacoda.com&gt;: > Glad to hear that.
