mvn build with -Pfastinstall not enabling noassembly flag?

[Aki Yoshida]

I would like to avoid the lengthy assembly step in the build at the
end when I quickly just build the camel project.

By looking at camel's parent/pom.xml, it seems that it was intended to
not assemble the distribution when built with the fastinstall profile.
    <profile>
      <id>fastinstall</id>
      <activation>
        <property>
          <name>fastinstall</name>
        </property>
      </activation>
      <properties>
        <maven.test.skip.exec>true</maven.test.skip.exec>
        <noassembly>true</noassembly>
      </properties>

but I see the assembly phase is always executed when I built it with
-Pfastinstall.

I can only disable the assembly step by setting the noassembly flag
explicitly like:

mvn -Dnoassembly=true -Pfastinstall

Not sure if anyone have this problem, it is intended that way or has
something to do with my environment?

thanks.
