-----------------------------------
    Steps to Reproduce: I have created a reproducer project [https://github.com/alistairblack/DROOLS-1744|https://github.com/alistairblack/DROOLS-1744] to demonstrate this issue. In this project there is a single rule module (ruleModuleOne) containing template based rules. This module is included in a master rule packaging module (rules) for repository deployment purposes. If you maven install the root project you will see a unit test failure as a result of the reported kbase inclusion issue.

> 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:
