There are spaces in the system TMP/TEMP directory paths. This issue is being tracked here: https://jira.atlassian.com/browse/BAM-12375
Resolution
This is a generic Git + Windows limitation. What happens is that Bamboo creates an SSH wrapper script in the current temporary directory and configures Git to use it via GIT_SSH variable. We need to use the wrapper to pass additional parameters to SSH.
This solution works fine, unless the platform is Windows and the temp directory name contains a space character. It's a bug in Git code used on Windows platform. We've fixed it and submitted a patch to Git developers.
The easiest solution is to change the temp directory. For instance, running the remote agent (or Bamboo server - depending where the job runs) with "java.io.tmpdir" set to a directory without spaces in the name helps to work around the issue.
