android - API 'variant.getExternalNativeBuildTasks()' is obsolete and has been replaced with 'variant.getExternalNativeBuildProviders()

Question

Using Android Studio 3.3 Canary 11 with the gradle plugin version 3.3.0-alpha11. It throws the following error when trying to sync gradle

WARNING: API 'variant.getExternalNativeBuildTasks()' is obsolete and has been 
replaced with 'variant.getExternalNativeBuildProviders()'.
It will be removed at the end of 2019.
For more information, see https://d.android.com/r/tools/task-configuration- 
avoidance
Affected Modules: app

Clicking on the error leads me to this line in the gradle file

applicationVariants.all { variant ->
            variant.outputs.all {
                outputFileName = "${variant.name}-${variant.versionName}.apk"
            }
        }

What exactly do I need to change here?

I have skipped out a few constants and other sensitive information in the app/build.gradle file.
