[maven] Maven: How do I activate a profile from command line?

Activation by system properties can be done as follows

<activation>
    <property>
        <name>foo</name>
        <value>bar</value>
    </property>
</activation>

And run the mvn build with -D to set system property

mvn clean install -Dfoo=bar

This method also helps select profiles in transitive dependency of project artifacts.
