Build error --> Not a v4.0.0 POM --> add modelVersion Tag to pom

[uelihofstetter]

Your build may breaks because the modelVersion Tag in your pom file is
missing (indicated by: Reason: Not a v4.0.0 POM.) and so the xstream.jar is
not used.
 

So add the modelVersion tag  <modelVersion>4.0.0</modelVersion> to your
xstream pom file.
