Description

I'm getting a NullPointerException when invoking "mvn release:prepare
-DdryRun=true" (don't know, if the dryRun-parameter makes any
difference). See the stack trace below.

My POM does make use of the wagon-ssh-extension, but without declaring a certain version of that extension - which is not necessary, as far as I know.

A workaround to this is to declare a version to the extension.

See this mail thread for a discussion on this issue: <http://www.nabble.com/NullPointerException+in+Release+Plugin+2.0-beta-4-t1637385.html#a4434481>
