Having trouble with setting a property in settings.xml and activating a profile in a pom based on that property

[David <dn...@gmail.com>]

Hello All,

I'm trying to set a property in the settings.xml file and then have a
profile in the pom.xml file activate if that property is set.  Right now I
don't care about the value, I just need it to be set.  Currently I have the
following in my settings.xml file.

<profile>
  <id>A</id>
    <activation>
      <activeByDefault>true</activeByDefault>
    </activation>
    <properties>
      <david>C:\temp</david>
    </properties>
</profile>

In my pom.xml I have the following.

<profiles>
        <profile>
            <id>B</id>
            <activation>
                <property>
                    <name>david</name>
                </property>
            </activation>
...
<profiles>

I can see from running mvn help:active-profiles that profile A in the
settings.xml file is active but profile B is not.  I can also use the David
property in other areas of the pom file.  I'm I doing something wrong?  I'm
using Maven-2.0.6 on Windows.

Thanks,

David

David,

this gave me hard time too. After a while I realized, that profiles
can only be activated by *system* properties which is a different
beast than those properties one can define in a POM or the settings.
System properties are those which are provided to maven by the command
line parameter "-D".

http://maven.apache.org/guides/introduction/introduction-to-profiles.html
explicitely uses the term "system property" when it comes to profile
activation by property values.
