title: How to force a package to be installed?
body: <p>I'm trying to install the following package through <code>composer</code>:</p>
  
  <p><a href="https://packagist.org/packages/cartalyst/sentry#dev-feature/laravel-5" rel="noreferrer">https://packagist.org/packages/cartalyst/sentry#dev-feature/laravel-5</a></p>
  
  <p>When I do:</p>
  
  <pre><code>composer require cartalyst/sentry dev-feature/laravel-5
  </code></pre>
  
  <p>I always receive this error:</p>
  
  <pre><code>[InvalidArgumentException]
  Could not find package dev-feature/laravel-5 at any version for your minimum-stability (stable). Check the package spelling or your minimum-stability
  </code></pre>
  
  <p>If I change <code>minimum-stability</code> to <code>dev</code> it will still complain.</p>
  
  <p>However, if I install <code>dev-master</code> and manually merge the files from <code>dev-feature/laravel-5</code> into <code>dev-master</code>, it works fine.</p>
  
  <p>Hence why I'm asking how to force this package to be installed via <code>composer</code>.</p>
