WARNING: API 'variant.getMappingFile()' is obsolete and has been replaced with 'variant.getMappingFileProvider()' : <p>I just updated Android Studio 3.5 to Android Studio 3.6 and replaced previous Gradle plugin with Gradle plugin 3.6.0 when syncing Gradle:</p>

<blockquote>
  <p>build.gradle: API 'variant.getMappingFile()' is obsolete and has been
  replaced with 'variant.getMappingFileProvider()'</p>

<p>Any suggestions on how to debug this warning. Where is it coming from? I don't see any usage of getMappingFile in my code although, might be some library. Suggestions to debug these kind of cases would be helpful </p>
