Sven Ludwig commented on MNG-3228:
----------------------------------
I have made the following observations with Maven 2.2.1.
I have three poms, a parent, a child, and an aggregator. The aggregator
includes the child directly as a module, but not the parent. The parent is the
parent POM of the child. I am running the build with "mvn clean install" on the
aggregator.
I wrote a profile with a configuration of some plugins that are usually not
applied within my project hierarchy, i.e. the occurrences of these plugins in
the profile defined in the parent POM are the only ones. Therefore, when I run
my build, I can easily see if the profile is in effect, since I can see whether
not not the extra plugins were executed.
In the following constellations, the profile was active during the build:
1.1 Activation via System Property defined in the parent. Profile not mentioned
in the child at all. System Property set on the console.
1.2 Same activation via System Property defined in the parent and in the child.
System Property set on the console. In this case however, the profile would
also be active when building only the parent itself, an unwanted effect.
1.3 No explicit activation defined in the parent nor the child. Profile not
mentioned in the child at all. Profile included in activeProfiles in
settings.xml. In this case however, the profile would also be active when
building only the parent itself, an unwanted effect.
In the following constellations, the profile was NOT active during the build:
2.1 Activation via System Property defined in the parent. Profile not mentioned
in the child. Maven Property set within the child.
2.2 No explicit activation defined in the parent. Activation via System
Property defined in the child. Maven Property set within the child.
It appears that the property resolving mechanism for the activation of plugins
has already been changed for Maven 3. There, the normal Maven Properties are
evaluated, not only the System Properties. I do not know if it has been
considered to include this nice behavior also in Maven 2, I personally would
like to see that.

> Project: Maven 2 & 3
> Issue Type: Bug
> Affects Versions: 2.0.7
> Reporter: tony nys
> Assignee: John Casey
> Fix For: 2.1.0
>
>
> The goal is to activate a maven profile based on OS user name.
> When I create a standalone project with a profile activation, it works,
> however, when I define the profile in a "parent" pom, it is never activated.
> this works:
> ...
> <profile>
> <id>TONY</id>
> <activation>
> <property>
> <name>user.name</name>
> <value>WINTONY</value>
> </property>
> </activation>
> <properties>
> </properties>
>
> So in this case, my profile is activated based on my OS user name
