title: Could not find android.arch.core:core-testing:2.1.0
body: <p>I am getting the following error when running my tests:</p>
  <blockquote>
  <p>Could not resolve all files for configuration ':app:debugUnitTestCompileClasspath'.
  Could not find android.arch.core:core-testing:2.1.0.</p>
  </blockquote>
  <p>If it's of any help, I am using Android Studio Arctic Fox | 2020.3.1 Canary 6</p>
  <p>Full stacktrace (screenshot, otherwise is way too long):</p>
