Description

I'm using antrun in my project to create an IzPack installation. The plugin configuration is below.

When maven is run from the top-level project, the ant taskdef fails because it cannot find the IzPackTask class. However, when I run maven from the subproject itself, it works fine. Not sure if this is related to http://jira.codehaus.org/browse/MANTRUN-49. The error message from maven is at the bottom.
