Subject [jira] [Commented] (MNG-5956) Invalid DuplicateProjectException if physically same pom.xml

    Patch for MNG-5956

    Issue raised
    If you use modules, and that results in the same project/pom being included multiple times
then an exception is thrown. But as it's the exact same project/pom it can simple be ignore
in my view.
    Simple project structure;
    If sub1 has nested modules but for some reason common should 50% of the time be rebuilded
if sub1 i rebuilt then adding ../common aids developers.
    if sub2 has a similar setup to sub2, then when you build at the root directory an error
is produces as both sub1 and sub2 reference common.
    This pull request should ignore where the project is an exact match of the same physical

> Several projects I've worked on have lots of modules, some to aid developers sub modules
have been hijacked to also build other projects. Take the following example.
> ./pom.xml
> ./common/pom.xml
> ./sub1/pom.xml
> ./sub2/pom.xml
> If sub1 and sub2 both include <module>../common</module> then DuplicateProjectException
is thrown. I've created a patch which before throwing the exception does one last check to
ignore instances where the clash is actually the same physical pom file.
