ClassNotFoundException

You may need a modified settings.xml and if you already have M2_HOME set, you might see an error about "java.lang.ClassNotFoundException: org.codehaus.plexus.classworlds.launcher.Launcher" - just run unset M2_HOME. Here is a copy of a working settings.xml file:

<settings>
    <activeProfiles>
        <activeProfile>Rackspace Cloud Research</activeProfile>
    </activeProfiles>
    <profiles>
        <profile>
