             Summary: Inclusion of kbases containing rule templates results in duplicate rule names and kbase build failure.
                 Key: DROOLS-1744
                 URL: https://issues.jboss.org/browse/DROOLS-1744
             Project: Drools
          Issue Type: Bug
          Components: decision tables
    Affects Versions: 7.3.0.Final
            Reporter: Alistair Black
            Assignee: Mario Fusco


I am working on a multi-module BRMS project, with each module encapsulating a set of rules forming a single knowledge base. There is an empty "packaging" module which inherits each of these modules in order to generate a single KJAR for deployment purposes. The application then utilises this KJAR via the KieScanner/ReleaseId approach to facilitate dynamic rule loading at runtime and decoupling of application/rules.
Having taken the above approach I have encountered an issue when including knowledge bases that contain rule templates. Drools is unable to build these knowledge bases, reporting duplicate rule names; it appears to believe that the rules exist in both the inheriting and inherited knowledge bases. This behaviour is not seen when including knowledge bases containing standard rules or decision tables - just rule templates. 

An example of the error reported is:

{{4528 [main] INFO org.drools.compiler.kie.builder.impl.KieRepositoryImpl - KieModule was added: ZipKieModule[releaseId=my.drools.templates:ruleModuleOne:1.0-SNAPSHOT,file=C:\Users\black\.m2\repository\my\drools\templates\ruleModuleOne\1.0-SNAPSHOT\ruleModuleOne-1.0-SNAPSHOT.jar]
