I could not reproduce this issue.

I just tried following command on my master

mvn -DperformRelease=true release:perform -Darguments="-DskipTests" -Dtag=v0.6.0 -DreleaseVersion=0.6.0-incubating -DdevelopmentVersion=0.6.1-incubating-SNAPSHOT -DpushChanges=false -DconnectionUrl=scm:git:https://github.com/prabhjyotsingh/incubator-zeppelin.git

It fails with following error https://gist.github.com/prabhjyotsingh/0ca05096f30a6f176074

But after applying the patch it works. Or I could be missing out on some prerequisite.
