> I am unable to use the plugin buildnumber-maven-plugin to get the revision 
> number with Git and SVN. After some investigations, I realized that the 
> plugin used the Maven-SCM-API and their providers.
> The command issued by the plugin is
> {code}
> /bin/sh -c cd /tmp/temp/mytestingrepo && git rev-parse --verify --short=7 HEAD
> {code}
> I run this command directly in a shell with the following error
> {code}
> fatal: Not a git repository (or any of the parent directories): .git
> {code}
> When I modify the command like the following one, it works perfectly
> {code}
> /bin/sh -c "cd /tmp/temp/mytestingrepo && git rev-parse --verify --short=7 
> HEAD"
> {code}
> It seems that the command is not executed correctly on my environment where 
> the 
> {code}
> /bin/sh -c "cd /tmp/temp/mytestingrepo
> {code}
> is executed and afterwards the command
> {code}
> git rev-parse --verify --short=7 HEAD
> {code}
> is done in the current directory. In the case of SVN 1.7 and Git, the .svn or 
> .git are not located in subdirectories where the second command is executed.
