If I import a war using m2eclipse that refers to another project (which builds as a JAR) as a project reference, then I get this NPE when I try to deploy using deltacloud tools:

java.lang.NullPointerException

If I switch this to a normal jar dep, then the NPE goes away and the project deploys successfully.
