title: Can't resolve dependencies for androidx.fragment:fragment-testing
body: <p>I'm want to try out the new androidx fragment testing library from 
  <a href="https://developer.android.com/training/basics/fragments/testing" rel="nofollow noreferrer">https://developer.android.com/training/basics/fragments/testing</a> </p>
  
  <p>In my <code>app/build.gradle</code> I add the dependencies as described in the docs</p>
  
  <p><code>debugImplementation 'androidx.fragment:fragment-testing:1.1.0-alpha01'</code></p>
  
  <p>After syncing the project with gradle files I'm getting this error:</p>
  
  <p><code>Could not resolve androidx.fragment:fragment-testing:1.1.0.</code></p>
  
  <p>Did I missed something there? </p>
