Hi,

 

I am using the following code for adding DSLs to my knowledge base and I keep getting following error

My code :

 

    private KnowledgeBase loadRules(String[]  rules) throws Exception{

   

      KnowledgeBuilder builder = KnowledgeBuilderFactory.newKnowledgeBuilder();

      builder.add(ResourceFactory.newClassPathResource("/sample-dsl.dsl"),ResourceType.DSL);

      builder.add(ResourceFactory.newClassPathResource("/Rule1.dslr"), ResourceType.DSLR);

        if (builder.hasErrors()) {

        throw new RuntimeException(builder.getErrors().toString());

        }

        KnowledgeBase knowledgeBase = KnowledgeBaseFactory.newKnowledgeBase();

        knowledgeBase.addKnowledgePackages(builder.getKnowledgePackages());

        return knowledgeBase;

}

 

Error Stack:

Exception in thread "main" java.lang.NoSuchMethodError: org.drools.compiler.PackageBuilder.addKnowledgeResource(Lorg/drools/io/Resource;Lorg/drools/builder/ResourceType;Lorg/drools/builder/ResourceConfiguration;)V

      at com.org.RuleRunner.runStatelessRules(RuleRunner.java:127)

      at com.org.RulesTest.main(RulesTest.java:41)

 

 

I have added all the required .jars for processing knowledge builder.

I have the drools-compiler.jar5.0.1 added to my classpath ( I downloaded it online)

 

Could you point me towards where I could download  the correct drools-compiler and drools-core.jar files from?? Seems like the ones I have added to my classpath are not in harmony with each other.

 

Thank you. Please help.
