title: Force Gradle to use HTTP instead of HTTPS
body: <p>I am trying to build react-native android app, as a dependecy I see I have gradle, but it fails to load on build.
  Error message:</p>
  
  <pre><code>* What went wrong:
  A problem occurred configuring root project 'MobileApp'.
  &gt; Could not resolve all dependencies for configuration ':classpath'.
     &gt; Could not resolve com.android.tools.build:gradle:1.3.1.
       Required by:
           :MobileApp:unspecified
        &gt; Could not resolve com.android.tools.build:gradle:1.3.1.
           &gt; Could not get resource 'https://jcenter.bintray.com/com/android/tools/build/gradle/1.3.1/gradle-1.3.1.pom'.
              &gt; Could not GET 'https://jcenter.bintray.com/com/android/tools/build/gradle/1.3.1/gradle-1.3.1.pom'.
                 &gt; Connection to https://jcenter.bintray.com refused
  </code></pre>
  
  <p>The issue is clear, I am sitting behind corporate proxy that blocks any HTTPSconnections like these in error.
  So my questions are: how to force gradle to use HTTP in loading these files? Where these properties should be put(which of gradle files, i.e. gradle.properties)?</p>
  
  <p>P.S. I already have set these in gradle properties file:</p>
  
  <pre><code>systemProp.http.proxyHost= myHost
  systemProp.http.proxyPort= myPort
  systemProp.http.proxyUser= myUser
  systemProp.http.proxyPassword= myPassword
  </code></pre>
  
  <p>Any links, suggestions or etc. will help a lot.</p>
