Paul Gier updated MNG-3119:
---------------------------
Attachment: MNG-3119-maven-project-r558713.patch
Adding a patch that displays a warning message if an attempt is made to attach
a duplicate artifact.
I didn't see any existing exception classes that fit this scenario, so I
created a new exception class. The exception does not propagate any further
than the MavenProjectHelper in this case because I didn't want to break any
existing code (plugins, etc.) that may depend on the helper attach artifact
methods not throwing an exception.
> Duplicate attached artifacts should not be allowed.

>
> Currently, a project allows duplicate artifacts to be attached. This causes
> the second and other additional artifacts to overwrite the first attached
> artifact. This occurs during the package, install, and deploy phases.
> This can be reproduced by adding three instances of the source plugin (with
> different ids) to a project build configuration. The 2nd plugin will
> overwrite the first, and the third will overwrite the second.
> The desired behaviour is that the user should receive a warning or error when
> this happens.
