title: Composer classmap autoload does not load new files in folder
body: <p>The following problem: I have defined a classmap in my composer.json:</p>
  
  <pre><code>"autoload": {
      "classmap": [
          "app/controllers",
          "app/models",
          "app/helper.php"
      ]   
  }
  </code></pre>
  
  <p>However, when I create a new file in the "controllers" or "models" folder, it will not load them and I always have to make a composer dump-autoload.</p>
  
  <p>Is this the correct behavior? I thought the autoloader from composer monitors the folder for new files then?</p>
