Git is rapidly becoming the tool of choice for working with forks/patches of svn projects. MavenITmng1830ShowVersionTest fails if no svn repo is present.
The enclosed patches need to be applied in maven3 trunk (mng1830GitVersionNumber.patch), and adds a profile that activates a different buildnumber plugin setting
when no ".svn" folder is present.
I have made no attempts at being overly clever with the version number, which is basically "rGIT; <date>".
The second patch is for MavenITmng1830ShowVersionTest to accept this format in addition to the two others.
Since this fix is mostly in the test, there is no additional testcase.
