Description

I have a private repository on the bitbucket which is Symfony bundle and localy when I run composer update it ask me about password, because entry in my composer.json is similar to (please not about https instead of ssh.):

"repositories": [
        {
            "type": "vcs",
            "url":  "https://me@bitbucket.org/me/some-bundle.git"
        }
    ],

But when I deploy my app the task of deploy:vendors throws:

[RuntimeException]

Is there any option to tell deployer to ask for credentials during deploy?
