title: "Failed to resolve: org.junit:junit:4.12" with AndroidX Test JUnit
body: <p>When I try to add dependency on AndroidX Test JUnit 1.0.0-beta01: <code>androidTestImplementation androidx.test.ext:junit:1.0.0-beta01</code>, Gradle Sync fails with the following error:</p>
  
  <blockquote>
    <p>Failed to resolve: org.junit:junit:4.12</p>
  </blockquote>
  
  <p>All manipulations with adding org.junit dependency manually didn't help either.</p>
