title: Could not find gradle 3.1
body: <p>The latest version of gradle is 3.1 <a href="https://docs.gradle.org/current/release-notes" rel="noreferrer">enter link description here</a></p>
  
  <p>but Android Studio is only using 2.2?</p>
  
  <p><a href="https://developer.android.com/studio/releases/gradle-plugin.html#updating-gradle" rel="noreferrer">enter link description here</a></p>
  
  <p>This seems likes a huge discrepancy. My configuration:</p>
  
  <pre><code>buildscript {
      repositories {
          jcenter()
          mavenCentral()
          maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
      }
  
      dependencies {
          classpath 'com.android.tools.build:gradle:2.2'
          classpath 'de.felixschulze.gradle:gradle-hockeyapp-plugin:3.2'
          classpath 'com.michaelpardo:activeandroid:3.1.0-SNAPSHOT'
      }
  }
  
  allprojects {
      repositories {
          jcenter()
      }
  }
  </code></pre>
  
  <p>When I try to find gradle 3.1, I get an error that it cannot find it. Same now with 2.2    > Could not find com.android.tools.build:gradle:2.2.</p>
  
  <p>But gradle -v shows</p>
  
  <pre><code>gradle -v
  
  ------------------------------------------------------------
  Gradle 2.2
  </code></pre>
  
  <p>how do I resolve this?</p>
