Error ambiguous argument on executing gitcopy:set_current_revision

[yongzhenlow]

I'm running cap on ubuntu 14.04.1, git 2.8.1

The error seems to happen when gitcopy does a git rev-list

** Invoke gitcopy:set_current_revision (first_time)
** Execute gitcopy:set_current_revision
cap aborted!
SSHKit::Command::Failed: git exit status: 32768
git stdout: Nothing written
git stderr: fatal: ambiguous argument 'develop': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'

Tasks: TOP => gitcopy:create_release => gitcopy:create_tarfile => gitcopy:set_current_revision
(See full trace by running task with --trace)
