title: gradle behind proxy in Android Studio 1.3
body: <p>I've just upgraded Android Studio to version built on 28 July 2015. And proxy settings stopped working.</p>
  
  <p>I have them configured in AS preferences and in project's gradle.properties like this:</p>
  
  <pre><code>systemProp.http.proxyHost=some.proxy.adress.com
  systemProp.http.proxyPort=3128
  </code></pre>
  
  <p>And yet gradle build fails suggesting I should configure the proxy in either graddle properties or IDE.</p>
  
  <blockquote>
    <p>Error:Connection timed out: connect. If you are behind an HTTP proxy,
    please configure the proxy settings either in IDE or Gradle.</p>
  </blockquote>
  
  <p>What else can I try?</p>
  
  <p>P.S. Proxy works and is picked-up properly from Android Studio preferences, as git works as expected.</p>
