After running "mvn clean install" on the USC repo and then running "git status" the root pom.xml file is shown as modified with the following diff:

diff --git a/pom.xml b/pom.xml

This is dangerous and I don't think the build should be modifying it's own poms during a build run. Need to investigate what is causing this.
