Re: [rules-users] HELP - Problem creating package -validateUniqueRuleNames(PackageBuilder.java:830)

All my rules worked fine with Drools 3. NowI am trying to upgrade to Drools 5. I am using the following jar files to create binary (jar) files for my rules from command line: antlr-runtime.jar, drools-api.jar, drools-compiler.jar, drools-core.jar, drools-decisiontables.jar, drools-jsr94.jar, drools-templates.jar, janino-2.5.15.jar, joda-time.jar, jsr94.jar, jxl.jar, mvel2.jar, xpp3.jar, xpp3_min.jar, xstream.jar, org.eclipse.jdt.core_3.6.1.v_A68_R36x.jar This is my DSLR: package cit.coverage; expander Coverage.dsl rule "rrr" auto-focus true when He is nice then He is happy end This is my DSL Coverage.dsl: [condition][]He is nice=eval(true) [consequence][]He is happy=eval(System.out.println("HA HA")) I am trying to create binary(jars) using the following code: KnowledgeBuilderConfiguration kbc = KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration(); kbc.setProperty("drools.dialect.java.compiler", "JANINO"); KnowledgeBuilder builder = null; builder = KnowledgeBuilderFactory.newKnowledgeBuilder(kbc); Reader drlSource = new InputStreamReader(RVEngine.class.getResourceAsStream(ruleset.getDrlSourc e())); //ruleset.getDrlSource() = com/cit/myDrl.dslr Reader dslSource = new InputStreamReader(RVEngine.class.getResourceAsStream(ruleset.getDslSourc e())); builder.add(ResourceFactory.newReaderResource(dslSource), ResourceType.DSL); builder.add(ResourceFactory.newReaderResource(drlSource), ResourceType.DSLR); <-- problem KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages(builder.getKnowledgePackages()); no matter what I type in my dslr (drl) file I get the following exception on the highlighted line; I have 1 rule or 0 rule it still throws the same exception. Does it have to do with any jar files?
