Why does git fetch via hudson fail, while git fetch via the command line works?

Question

I'm trying to fetch a read-only git repository from github and have it be built via hudson. This process is failing.

This is the hudson output:

Started by an SCM change
Checkout:workspace / d:\hudson\home\jobs\gdcm-hudson\workspace - hudson.remoting.LocalChannel@19ba1d8
Using strategy: Default
Checkout:workspace / d:\hudson\home\jobs\gdcm-hudson\workspace - hudson.remoting.LocalChannel@19ba1d8

When I run that fetch command directly via the git bash command line, I get no response (which I assume means it's worked).

I looked at this possible solution: http://issues.hudson-ci.org/browse/HUDSON-7141?page=com.atlassian.jira.plugin.system.issuetabpanels%3Aall-tabpanel

But using that version of the plugin did not change this behavior.

I haven't even gotten to having it work with cmake yet, just downloaded consistently. How can I get this to work?

edit: This problem is not a repro of Problem cloning / fetching repository using Git plugin for Hudson on Windows, because I'm not running as a service on a server.

Yes, I just fixed this exact problem. If you open a windows explorer to d:\hudson\home\jobs\gdcm-hudson\workspace you should be able to see a .git directory and nothing else. There should be a working copy but there isn't. To fix this you have to "prime" the repository by running

git pull git://github.com/malaterre/gdcm.git

This should create a bunch of other files in d:\hudson\home\jobs\gdcm-hudson\workspace along side the .git directory and you should be able to perform a build in hudson.
