maven-release-plugin of current version works not

So far we use parent 1.486 which implies using `maven-release-plugin:2.2.2`.
It does have some problems with git in `release:prepare` stage, as discussed here: https://groups.google.com/forum/#!topic/jenkinsci-dev/qkmbl3HrYgk

To release 1.5.7 I had to manually specify the version to use like as follows:
`mvn org.apache.maven.plugins:maven-release-plugin:2.5:perform`.

However, latest Jenkins parent still uses 2.2.2.

Start by inspecting the Maven parent configuration that provides parent 1.486 and the maven-release-plugin version. Compare the release:prepare and release:perform behavior with plugin 2.2.2 and 2.5, using the issue's release command as the reproduction. Done means the Jenkins parent or project configuration uses a working plugin version without manual version specification.
