Tried approaches

• Java project with Gradle in IntelliJ IDEA: cannot resolve symbol 'google' but project compiles
  • sync proj with gradle files.
    => not work for me.
• Android Studio 出现“Cannot resolve symbol” 解决办法
  • Invalidate caches / restart
  • sync proj with gradle files.
  • comment out dependencies libs -> sync -> uncomment -> sync
  • modify dependencies libs version -> sync
  • delete /username/.gradle folder
    => none of the above approaches works for me.
• Cannot resolve symbol 'File' in settings.gradle
  • modify jdk version
