Help with car-maven-plugin site generation needed

[David Jencks]

I thought I might try to document the c-m-p a bit but when I try to run
mvn site

the javadoc plugin complains that I'm not using jdk 1.4 syntax.  I  
tried everything I could think of to set <source>1.5</source> but  
with no success whatsoever.  If anyone has a clue how to fix this  
please demonstrate!

btw I'm using maven 2.0.7 and wonder if we should make that a  
requirement.

thanks
