Default build profile for Maven

By using the attribute activeByDefault you will be able to select a default profile in Maven when no other profile is selected with the -P parameter.

<profiles>
    <profile>
        <id>da</id>                
    </profile>
    <profile>
        <id>live</id>
    </profile>
    <profile>
        <id>dev</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
    </profile>
</profiles>
