Could you add support for clone private repos?

With the current version it is possible. You just need some additional work to do it.

• Create access ssh key for your repository and put it somewhere on your redmine machine.
• Create a bash script to be used for GIT_SSH (gitlab_wrapper.sh). Don't forget to provide a valid path to your ssh key.

#!/bin/bash
ssh -i $DATA_DIR/mykeys/gitlab $1 $2

• In administration section of the plugin use Git command prefix field:

GIT_SSH=$GITLAB_WRAPPER_FOLDER/gitlab_wrapper.sh
