Alex Herbert commented on RNG-182:
----------------------------------

Added new module to deploy a BOM in commit:

84f3e81a99d429de52075f4a23d2e50197c1489c

The module uses a template BOM which is updated using maven resource filtering to obtain the project version and other properties. This is installed and deployed using customised install-file and deploy-file goals of the respective maven plugins.

The module is included in the site build and a simple page describing usage of the BOM has been added for the site and also the README page presented within github.

> In 1.5 the multi-module project rearranges a few methods to default interface methods in a different module. This is binary compatible. However it requires that all versions of the modules are matched. If the other modules are explicitly imported by a transitive dependency as a lower version then this will cause a runtime error due to missing methods.
>  
> I suggest we create a Bill of Materials (BOM) as a separate artifact to be deployed to maven for dependency management. Downstream users can then include this in their POM and all versions of the RNG modules would be matched.
