title: UnsupportedMethodException Android Studio 2.2
body: <p>I updated my android studio to 2.2.Now when I open and run previous project I got error UnsupportedMethodException.</p>
  
  <pre><code>Unsupported method: AndroidProject.getPluginGeneration().
               The version of Gradle you connect to does not support that method.
               To resolve the problem you can change/upgrade the target version of Gradle you connect to.
               Alternatively, you can ignore this exception and read other information from the model
