How do I fix this Gradle bug?

When I try and build for Android, I get the following error:

Code (CSharp):

1. Starting a Gradle Daemon, 1 incompatible Daemon could not be reused, use --status for details
2.  
3. > Configure project :launcher
4. WARNING: The option setting 'android.enableR8=false' is deprecated.

118. UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

I have spent a couple days trying various fixes, unsuccessfully. All of my Android Dependencies have been resolved. Does anyone know how I can solve this to make builds?
