We're using Hudson 1.149 and the Hudson Maven2 Project support.

When we execute the maven command "mvn clean deploy site site:deploy" from the
command line, everything works fine.

However, if we do the same thing in Hudson then the SCP fails when deploying the
site. Here is the Hudson/Maven output from the console.
