John Casey closed MASSEMBLY-471.
--------------------------------

       Resolution: Won't Fix
    Fix Version/s: 2.2-beta-6
         Assignee: John Casey

in Maven 2.x, plugin-level dependencies will only be picked up from maven's first encounter with the plugin. 

It's critical to list all plugin-level dependencies in a pluginManagement section of the parent POM to ensure they are included. This is a Maven design issue, not a problem with the assembly plugin.
