additional classpath to maven2

[Jagan Padmanabha Pillai -X \(jpadmana - Insight Solutions, Inc. at Cisco\)]

Hi,
 
Is it possible to add additional classpath (not specified in the
dependency) to maven2 on runtime.
The idea is to unzip the jars to a specific directory and add those jars
to compile / jar classpath.
 
Thanks
