JAL-3225 Using Gradle Git-Version plugin to set gitHash and gitBranch

Using Gradle Git-Version instead of exec to run git directly allows
buildship to successfully import the project into eclipse without a
command line git installed.  Essential for development within Eclipse in
Windows without having to install either gradle or git as command line
tools.
