While Android Studio Updated to v3.3 getting API ‘variant.getAssemble()’ is obsolete and has been replaced with ‘variant.getAssembleProvider()’

variant.assemble has been deprecated and replaced by a new provider API.

If for example you are using it as next:

variant.outputs.all { output ->
        variant.assemble.doLast {
            ....
        }
    }
}

Then replace it the new provider API:

variant.outputs.all { output ->
    variant.getAssembleProvider().configure() {
        it.doLast { 
            ....
        }
    }
}
