  <p>This is the error that is prompted:</p>
  
  <pre><code>Gradle 'shopping-app-android' project refresh failed:
           Build script error, unsupported Gradle DSL method found: 'release()'!
           Possible causes could be:  
           - you are using Gradle version where the method is absent 
           - you didn't apply Gradle plugin which provides the method
           - or there is a mistake in a build script
  </code></pre>
  
  <p>Please help!</p>
  
  <p>I have just started using Android Studio.</p>
