title: Issue with recyclerview dependency after migrating to androidx
body: <p>I'm completely rebuilding an old project, and have only kept the <code>xml</code> files (which show no error). I chose to update to androidx, and have synced all dependencies correctly, except for <code>recyclerview</code>. Whenever I try to sync, it would show the error log listed below.</p>
  
  <p><code>android:useAndroidX=true</code> and <code>android:useJetifier=true</code> are both set in <code>gradle.properties</code> file. No errors were detected in any <code>xml</code> file. I triedd Invalidating caches/restarting, rebooting the whole system, and cleaning the project. I actually don't know what else to do.</p>
  
  <p>The error is happening only when I add one or both these dependencies:</p>
  
  <pre><code> implementation 'androidx.recyclerview:recyclerview:1.1.0-alpha05'
   implementation 'androidx.recyclerview:recyclerview-selection:1.1.0-alpha05'
  </code></pre>
  
  <p>I tried adding and removing each dependency individually. only those produced the error.</p>
