build.gradle on project level has a new format in Android. How to change my existing gradle setup to a new one?
I have been away for a year for developing Android apps. I noticed the build.gradle of project level has a new format:
FROM:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
ext.kotlin_version = '1.3.61'
ext.retrofit_version = "2.6.0"
ext.coroutines_version = "1.3.0"
ext.room_version = '2.4.2'
ext.glide_version = "4.8.0"
ext.nav_version = '2.4.2'...
