We have an organizational pom that every project inherits from. When we build
this project from the command line directly, using mvn clean deploy site, it
builds fine. However, when we schedule this to build via Hudson's Job interface,
we get the following console output below. The parent pom is installed in
~/.m2/repository and settings.xml contains the repository locations. When we use
hudson 1.119 (with maven 2.0.8), it all works fine. We're currently at maven
2.0.8 and hudson 1.161.
