FirebaseAuthJava client, I was getting this error:
Execution exception[[IllegalStateException: FirebaseApp name [DEFAULT] already exists!]]
FirebaseApp.initializeApp()was getting called again from the application loader, which caused this error.
Try), and if it doesn't exist, we initialize it, which should happen just once.
val firebaseApp: FirebaseApp = FirebaseAppLoader(credentials). Or with macwire,
val firebaseApp: FirebaseApp = wireWith(FirebaseAppLoader(_)).
