Using public group projects with PHP Composer

How to Use GitLab
1

Hello,

I’d like to use a GitLab group and its projects with PHP Composer.

My composer.json:

{
    "repositories": [
      {
        "type": "git",
        "url": "https://gitlab.com/<MY-GROUP>"
      }
    ]
}

However, when I use composer require <MY-GROUP>/<MY-PROJECT>, I get the following:

  [RuntimeException]
  Failed to execute git clone --mirror 'https://oauth2:***@gitlab.com/<MY-GROUP>' '/U
  sers/kolja/.composer/cache/vcs/https---gitlab.com-<MY-GROUP>/'

  Cloning into bare repository '/Users/kolja/.composer/cache/vcs/https---gitlab.com-<MY-GROUP>'...
  fatal: unable to update url base from redirection:
    asked for: https://oauth2:***@gitlab.com/<MY-GROUP>/info/refs?service=git-upload-
  pack
     redirect: https://gitlab.com/users/sign_in

I use Composer and GitLab with repositories in my account, and there it works. What am I doing wrong? The group and its projects are all public and have no restrictions.

Thanks for your help.
