useLastCommittedRevision on git returns `null`

[bmarwell]

When setting useLastCommittedRevision, git repos will return null.
If I am not mistaken, in git there is nothing but a last committed revision (i.e. no revision for current workspace).

The code says:

https://github.com/mojohaus/buildnumber-maven-plugin/blob/master/src/main/java/org/codehaus/mojo/build/AbstractScmMojo.java#L272-L293

        if (useLastCommittedRevision) {
            // It seemed the case that for git getLastChangedRevision()
            // returns null instead of the last revision in contradiction
            // to the above code: scmResult.getInfoItems().get(0);

Maybe it should either

• throw an error
• fetch the last version of the repo

Description is:

whether to retrieve the revision for the last commit, or the last revision of the repository.

So maybe it is in combination with doCheck = false // doUpdate = false?
