use "push" with sub_directory

[bitsmyth]

Can somebody explain me what I am doing wrong here? I want to pull a subdirectory from my repository (later in CI) and for this I have set sub_directory. I have successfully provisioned the server with deployer - really nice experience, great work - especially with the overrides! Now I would like to push the local state to the server, but I am getting errors.

- repo
   - laravel
      - deploy.php

set('repository', 'https://github.com/user/repo.git');
set('sub_directory', 'laravel');     // <--- pull only laravel dir
set('application', 'app');
set('deploy_path', '~/{{application}}');

cd repo/laravel && vendor/bin/dep push     # <--- executing from repo/laravel

task push

It seems to me that rsync wants to upload a non existent path because it prefixed twice laravel for composer.json and composer.lock. But I don't know how to fix this.

I went into push command and understood that it just uploads the git diff. To conclude, I first had to pull the repo on remote.
