Quick jist:
1. Use maven-install-plugin's
install-file<http://maven.apache.org/plugins/maven-install-plugin/install-file-mojo.html>goal
to make maven artifacts out of the jars you intend to unpack, and do
it in any phase prior to process-classes (or do this first in the
process-classes phase).
2. Use maven-dependency-plugin's unpack
goal<http://maven.apache.org/plugins/maven-dependency-plugin/unpack-mojo.html>to
extract those artifacts to ${project.build.outputDirectory} in the
process-classes phase after the above phase.

I think that'll do it for you.
