I'm not sure if I have configured something wrong or if I have encountered a glitch in this plug-in. After installing the shared-workspace plug-in I:

1) created a new shared workspace under "Configure System" on the "Manager Jenkins" page for my Jenkins server
2) selected the newly created shared workspace from the "Shared Workspace" drop down in the configuration page for the build job intended to use it
3) entered "${SHAREDSPACE_SCM_URL}" into the "Repository URL" field for the Git repository the build job uses

The first manual run of the build job resulted in the repository being cloned to the expected default "sharedspace" directory and the build ran successfully. Unfortunately the job which is configured to poll for changes in the configured Git repository is no longer being triggered by changes that are pushed to the repository. The Git polling log for the job shows an error reading:

"Fetching upstream changes from origin
ERROR: Problem fetching from origin / origin - could be unavailable. Continuing anyway
hudson.plugins.git.GitException: Command "fetch -t origin +refs/heads/:refs/remotes/origin/" returned status code 128:
stdout:
stderr: fatal: '${SHAREDSPACE_SCM_URL}' does not appear to be a git repository
fatal: Could not read from remote repository."

It looks like the ${SHAREDSPACE_SCM_URL} token is not being resolved to the correct repository URL unless I have something misconfigured here.

Thanks in advance for any help with this and if there is a better place for me to log this kind of question please let me know.
