when I tried to also use the Hudson Maven Release Plug-in Plug-in with it, it
always failed to authenticate...

This was because it was using http instead of https to do the checkout. I had
set "Google Code (Automatic Configuration)" on Source Code Management of the
hudson project. Instead of relying on Hudson GoogleCode plugin, I used
Malachi's workaround posted at
http://malsserver.blogspot.com/2009/04/hudson-maven-release-plug-in-plug-in.html
which use Subversion as Source Code Management and entered the https url for my
project.

Would it be possible for you to fix this?

Many thanks!
