google repo on Windows with MinGW Git, issue in referring local mirror with --reference option

[Himanshu Singh]

[Below testing is done recently with repo version 1.25]

Google repo tool has been updated to support Windows OS. I am able to run basic commands like repo init and repo sync using repo tool on Windows (which makes use of MinGW Git on Windows). In my work I need to create a local mirror of a repository and then use it. repo tool works fine to create mirror repository.

Here are commands used to create mirror repository on local drive on Windows OS.

$ repo.cmd init -u <URL> -b <branch_name> -m <manifest_file_name> --mirror

$ repo.cmd sync --no-tags

• The above commands create the mirror in local drive C:\git-repo\test\mirror-testing\mirror
  

But when I refer the above mirror to sync in other drive (C:\git-repo\test\mirror-testing\client) then it shows error.

Command:
$ repo.cmd init -u <URL> -b <Branch_name> -m <manifest_file_name> --reference="C:\\git-repo\\test\\mirror-testing\\mirror"

Error:
error: object directory C:/git-repo/test/mirror-testing/mirror/project/manifest.git/objects? does not exist; check .git/objects/info/alternates.

The above command creates alternates file in C:\git-repo\test\mirror-testing\client\project\manifest.git\objects\info\ directory and that file contains below path:

C:\git-repo\test\mirror-testing\mirror\project/manifest.git\objects




Has anyone used Google repo on Windows for creating mirror and syncing in other drive using as reference?
