Thanks guys for checking this out so quickly!

Matt's tips got the issue fixed for me: "/usr/bin/mvn" was really in the way.

>                 Key: MNG-4442
>                 URL:
>             Project: Maven 2
>          Issue Type: Bug
>          Components: Bootstrap & Build
>    Affects Versions: 3.0-alpha-3
>         Environment: Mac OS X 10.5.8
>            Reporter: Tiago Fernandez
>            Assignee: Benjamin Bentmann
> After installing Maven 3.0-alpha-3 on Windows I can check its version without any problem,
but that's not the case for OS X:
> MacBook-Pro:~ tiago$ mvn -v
> Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/classworlds/Launcher
> Renaming ${M2_HOME}/boot/plexus-classworlds-2.2.2.jar to ${M2_HOME}/boot/classworlds-2.2.2.jar
fixes the issue, but I am sure this ain't the proper fix.
> Possibly related issue: MNG-2692
