maven-shade-plugin classpath

[Ryan Wexler]

I am using the ManifestResourceTransformer of the maven shade plugin to
create an executable jar from an existing jar.

I would also like to add the classpath and set a classpathprefix like you
can do using the normal maven jar.
    <addClasspath>true</addClasspath>
    <classpathPrefix>lib/</classpathPrefix>

Is there a way to do this with the shade plugin?

thanks
