title: Getting a "No such remote or remote group" error when trying to use a private repo in Composer
body: <p>I'm getting an error when I try to run composer. I have the following in my <code>composer.json</code>:</p>
  
  <pre class="lang-js prettyprint-override"><code>{
      "require": {
          "my/private-repo": "dev-development"
      },
      "repositories": [
              {
              "type": "git",
              "url": "git@bitbucket.org:my/private-repo.git"
          }
      ],
  }
  </code></pre>
  
  <p>In that private bitbucket repo, there's a composer.json with a name of "my/private-repo", and there's a branch called development.</p>
  
  <p>When I try to run composer, I get this error: "Failed to update git@bitbucket.org:my/private-repo.git, package information from this repository may be outdated (fatal: No such remote or remote group: origin". I have no idea why it's mentioning origin at all; I've got that private repo in a totally separate folder on this composer, so it shouldn't be looking in there. I can git clone my/private-repo just fine, so it's not an SSH issue. Any ideas?</p>
