Active profiles recursively growing
-----------------------------------
Key: MPH-42
URL: http://jira.codehaus.org/browse/MPH-42
Project: Maven 2.x Help Plugin
Issue Type: Bug
Affects Versions: 2.0.2, 2.1
Reporter: Sander Verhagen
Priority: Critical
Attachments: Active-profiles-recursively-growing.diff.txt
Running the active-profiles goal in a project where parents introduce profiles,
any sub-modules of these parents will report a number of duplicates of these
profiles that grows each time the goal is invoked.
This is caused by the plugin (recursively) retrieving profiles from subsequent
parents, and adding them to the project on which the goal is invoked. The
plugin means to add the profiles that it finds so that it can give an
aggregated listing of profiles over the full inheritance tree of the project on
which the goal is invoked (which is okay), it is mistaken in actually adding
them to the project on which the goal is invoked. It changes the project on
which the goal is invoked, rather than merely observing it. Because the plugin
keeps on adding the same profiles from parent projects, every time it is
invoked, to the same project on which the goal is invoked, the aggregated
listing keeps on growing and growing during execution.
Rated this Critical since on large projects this renders the plugin useless;
the output will become booming; well, you know how that goes with recursion.
Fix is attached as unified diff.
