[rules-users] KnowledgeAgent doesn't load dsl files and dslr file from a change-set correctly

I have a folder in classpath: dsl/global.dsl rules/section-A.dslr rules/section-A/page-1.dslr I create a knowledge base like this: public KnowledgeBase createKnowledgeBase() throws DroolsParserException, IOException { KnowledgeBuilder knowledgeBuilder = KnowledgeBuilderFactory .newKnowledgeBuilder(); knowledgeBuilder.add(ResourceFactory .newClassPathResource("dsl/global.dsl"), ResourceType.DSL); knowledgeBuilder.add(ResourceFactory .newClassPathResource("rules/section-A.dslr"), ResourceType.DSLR); knowledgeBuilder.add(ResourceFactory .newClassPathResource("rules/section-A/page-1.dslr"), ResourceType.DSLR); if (knowledgeBuilder.hasErrors()) { throw new RuntimeException(knowledgeBuilder.getErrors().toString()); } KnowledgeBase knowledgeBase = KnowledgeBaseFactory.newKnowledgeBase(); knowledgeBase.addKnowledgePackages(knowledgeBuilder.getKnowledgePackages()); return knowledgeBase; } // code knowledgeBase = createKnowledgeBase(); session = knowledgeBase.newStatefulKnowledgeSession(); // insert facts session.fireAllRules(); session.dispose(); The above code works and I can get a unit test to work that processes rules accordingly. I can see my dslr converting to a drl using the "drl viewer" correctly (provided I temporarily place the dsl file in the same location since expander doesn't accept a relative path). The problem, however is when I use a change-set.xml and a KnowledgeAgent, things don't work code for loading via knowledgeAgent public static KnowledgeBase loadKnowledgeBase() throws DroolsParserException, IOException { agent = KnowledgeAgentFactory.newKnowledgeAgent("msll agent"); agent.applyChangeSet(ResourceFactory.newClassPathResource("change-set.xml")); return agent.getKnowledgeBase(); } <change-set xmlns='http://drools.org/drools-5.0/change-set' xmlns:xs='http://www.w3.org/2001/XMLSchema-instance' xs:schemaLocation='http://drools.org/drools-5.0/change-set.xsd' <add <resource source='classpath:dsl/' type='DSL' /> <resource source='classpath:rules/' type='DSLR' /> <resource source='classpath:rules/section-A/' type='DSLR' / </add</change-set I get the following generic drools errors: ERR 103] Line 4:0 rule 'rule_key' failed predicate: {(validateIdentifierKey(DroolsSoftKeywords.RULE))}? in rule[7,0]: [ERR 101] Line 7:0 no viable alternative at input 'import' in rule Con in rule attribute ... ... The rules are same, folder location is the same. I believe that drools has a problem resolving path (expander global.dsl) from the dslr file when using a KnowlegeAgent since in the earlier strategy, one could build a dsl into the knowledgeBuilder directly from the classpath.
