Unable to obtain archiver for extension 'zip'

There seems to be a regression in maven-3-beta-3 related to the assembly plugin. When building a multi-module project using Maven 3-beta-3 I get the error "Unable to obtain archiver for extension 'zip'". This error does not happen with Maven 3-beta-2.

I wasn't able to reproduce this problem with a smaller project. The source can be checked out from the jboss repo

svn co -r 107936 http://anonsvn.jboss.org/repos/jbossas/trunk

The problem can be seen running building certain modules.

mvn clean install -pl deployment,server,osgi/zip

I will try to narrow down the problem further if I have some time.
