This produced the same result (error). Based on Doron's suggestion earlier in the thread I decided to throw more memory at the problem. I then received a java.lang.OutOfMemoryError: PermGen space error, setting MAVEN_OPTS="-XX:MaxPermSize=128m" seems to have fixed this and I have now built sucessfully. Thankyou for your suggestions!

I have added the perm gen space error tip to http://www.ovirt.org/wiki/Building_oVirt_engine#Build, more generally we probably need to consider some hints/recommendations around what kind of computing power (particularly memory) is required to successfully compile the project.
