Hi Guys,
I'm a pretty recent Drools user.

I'm trying to update a project to stop using the deprecated KnowledgeBase.
I've followed examples on 
http://blog.athico.com/2013/10/configuration-and-convention-based.html
<http://blog.athico.com/2013/10/configuration-and-convention-based.html>  ,
but an exception is being thrown when trying to build the KieBases.

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();
...

The following exception is thrown:
