I've seen this problem a few places while searching for a solution. Is it possible to overcome this issue? Drools version:6.0.0.Final Java version: 1.7.0_45 Code snippet: ... final KieServices ks = KieServices.Factory.get(); final KieRepository kr = ks.getRepository(); final KieFileSystem kfs = ks.newKieFileSystem(); //ruleScript is simply a string containing the rules kfs.write("src/main/resources/com/company/test/rules/rules.drl", ruleScript); KieBuilder kb = ks.newKieBuilder(kfs); kb.buildAll(); if (kb.getResults().hasMessages(Level.ERROR)){ configuration.getLog().error("\nSomething wrong here!\n\n"); } final KieContainer kContainer = ks.newKieContainer(kr.getDefaultReleaseId()); session = kContainer.newKieSession(); Exception: java.lang.RuntimeException: Cannot find KieModule: org.default:artifact:1.0.0-SNAPSHOT at org.drools.compiler.kie.builder.impl.KieServicesImpl.newKieContainer(KieServicesImpl.java:86) Thanks -- View this message in context: http://drools.46999.n3.nabble.com/Cannot-find-KieModule-org-default-artif...
