Building plugin without Git causes crash

[RexValkering]

On a Ubuntu server, I decided to download the plugin by using wget rather than using git clone. Building the plugin went fine, but when I tried to use it with my GlusterFS-Hadoop install, the following error occurred:

hadoop@gluster1:/usr/local/hadoop/bin$ ./hdfs dfs -ls

Installing git and cloning the repository solved this problem. It seems to be dependent on the .git info in the repository and not Git itself, since uninstalling Git and rebuilding it caused no problems either.

This is a great catch. The current builder expects git to be installed, and then, calls the git API to read the info about the commit, etc. I think we could print the maven version info instead, if we wanted to be a little bit more universal.

#96 fixes it. thanks for the feedback ! Would never have caught this myself.
