title: Generating proxies with Doctrine
body: <p>I have cleared my symfony2 application and now cannot run the application because cannot generate proxies for entities from the command line while a few have actually been generated by default.</p>
  
  <p>I have tried to run the command below which usually did the trick in earlier versions of symfony/ doctrine:</p>
  
  <pre><code>php bin/console doctrine:ensure-production-settings --no-debug --env=prod
  </code></pre>
  
  <p>But this time I only get the following response:</p>
  
  <pre><code>Query Cache uses a non-persistent cache driver, Doctrine\Common\Cache\ArrayCache.
  </code></pre>
  
  <p>Anyone know how to solve this?</p>
