Do you have git installed ? Edeliver adds your build machine as remote and uses the ssh protocol to push the source code of your app there. you can check that by running git remote -v show in you project directory after building on the build host. It shows something like that:
$ git remote -v show
$BUILD_USER@$BUILD_HOST $BUILD_USER@$BUILD_HOST:$BUILD_AT (fetch)
$BUILD_USER@$BUILD_HOST $BUILD_USER@$BUILD_HOST:$BUILD_AT (push)
origin git@your_remote(fetch)
origin git@your_remote(push)
