Installing a rails plugin using the git:// protocol is easy, you just type
script/plugin install git://server.local/my_git_repo.git
How do I install a plugin from a git repo hosted over ssh?
When I type
script/plugin install myuser@myserver.com:plugin.git
I get "Plugin not found"
I know it's not a git issue because the installer doesn't even prompt me for my ssh password.
script/plugin can not currently handle git over ssh.
Instead you're just going to have to clone the repository manually from the vendor/plugins directory.
$RAILS_ROOT/vendor/plugins $ git clone ssh://myuser@myserver.com:plugin.git
The plugin script also removes the hidden directories, .git and .git-ignored from the newly cloned copy.
