Error: Cannot find symbol @NonNull Task, v1.2.0

[xempie]

I recently updated react native and RN android location enabler but I get this error when I run the project:

=========================================

Task :react-native-android-location-enabler:compileDebugJavaWithJavac FAILED

FAILURE: Build failed with an exception.

"react": "^16.10.1",
"react-native": "0.57.8",
"react-native-android-location-enabler": "^1.2.0",

Anyone knows how to fix it?

This works for me:

Add the following two flags to true in your gradle.properties file at ProjectFolder/android/gradle.properties

android.useAndroidX=true
android.enableJetifier=true

Execute

npm install --save-dev jetifier
npx jetify
npx react-native run-android

In your package.json add the following to scripts
"postinstall" : "npx jetify"

Extra: At ProjectFolder/android delete .idea folder in case that cache it's causing a trouble.
