[FIXED] Composer require branch name

Issue

For example I want to require:

{
  "repositories": [
    {
      "type": "git",
      "url": "https://github.com/google/google-api-php-client.git"
    }
  ],

  "require": {
    "google/apiclient": "v1-master"
  }
}

In this example I try require google/apiclient on branch v1-master. I get error:

  [UnexpectedValueException]                                                        
  Could not parse version constraint v1-master: Invalid version string "v1-master"

Solution

You need to prefix all dev branches (= non tagged) by dev-.

To install the branch you need, use:

composer require google/apiclient:dev-v1-master

See composer docs.
