Description

This week while playing with weaver, trying to write a weaver for a Spring project, I tried to see the help with the following command:

mvn clean org.apache.commons:commons-weaver-maven-plugin:help

But it failed with the following message:

If I try to run prepare with

mvn clean org.apache.commons:commons-weaver-maven-plugin:prepare

it works fine.
