Ryan Stewart commented on MNG-5055:
-----------------------------------
I'm a little confused. Is this issue about activating profiles based on POM
properties or not? If so, that's what I'm looking for. Is there another issue
somewhere I should vote for? It would be an immensely useful feature, and I
can't really see a good reason why it shouldn't work that way.
> Allow to activate property-based profile by POM property
> --------------------------------------------------------
>
> Key: MNG-5055
> URL: http://jira.codehaus.org/browse/MNG-5055
> Project: Maven 2 & 3
> Issue Type: New Feature
> Affects Versions: 2.2.1, 3.0.3
> Environment: Tested with M3.0.2 and M2.2.1 on MacOS X (OS surely not
> relevant)
> Reporter: wolfgang häfelinger
> Attachments: MNG-3228.zip

>
> This demo consists of four file:
> (1) README.txt
> (2) pom.xml
> (3) parent-pom.xml
> (4) pom-no-profile-no-dep.xml
> File" pom.xml" is the POM expected to activate profile "logging" defined in
> "parent-pom.xml". This does not work as clearly outlined in the original bug
> report MNG-3228 [http://jira.codehaus.org/browse/MNG-3228].
> File "pom-no-profile-no-dep.xml" is essentially the same as file "pom.xml".
> Section <dependencies /> and profile activation has been removed in order to
> get goal "help:effective-profiles" working.
> The demo works like this: Install parent POM in local cache
> (~/.m2/repository).
> % mvn -f parent-pom.xml install
> Then try this:
> Test 1:
> % mvn -f pom.xml package
> => error
> Test 2:
> % mvn -f pom.xml package -Dactivate-profile-logging=true
> => good
> Test 3:
> % mvn -f pom.xml package -Plogging=true
> => good
> Test 4:
> % mvn -f pom-no-profile-no-dep.xml help:active-profiles
> => profile "logging" is not shown (expeced, but see next test)
> Test 5:
> % mvn -f pom-no-profile-no-dep.xml help:active-profiles
> -Dactivate-profile-logging=true
> => does not show profile "logging" although "logging" must be active
> (otherwise: why would second test work?)
> Summary:
> 1. maven-help-plugin can't be trusted on reporting active profiles.
> 2. Activating inherited profiles differs from activating local profiles.
> The second issue is clearly (!) a design bug cause there is no good reason
> why inherited elements behave differently from local elements.
