object.Exception ... Failed to execute 'git describe'

[BoQsc]

I just tried to run a project via specifying dvm as dependency using dub, and I've got this error that mentions "Failed to execute 'git describe'"

object.Exception@C:\Users\vaida\AppData\Local\dub\packages\dvm-0.5.0\dvm\tools\generate_version.d(25): Failed to execute

DVM is currently not intended to be used as a library or a dependency. I'm guessing that Dub does not clone the DVM repository but instead uses the GitHub API to download the code. Therefore it doesn't have a git repository and git describe fails for this reason.

Perhaps I can add a fallback version as a workaround.
