Answer 1

repositories {
   jcenter()
   ...
   // You need to add the following repository to download the
   // new plugin.
   maven { url "https://maven.google.com" } //THIS
   google() //OR THIS
}

Also delete .gradle and gradle folder and resync the project. Issues with caches

Answer 2

You have to add the maven google also in the buildscript block in the top-level build.gradle file:

buildscript {
    repositories {
       jcenter()
       ...
       // You need to add the following repository to download the
       // new plugin.
       maven { url "https://maven.google.com" }
    }
   dependencies {
       classpath 'com.android.tools.build:gradle:3.0.0-beta6'
       //...
   }
}

This version of the plugin also requires an update version of gradle. You have to update the distributionUrl in gradle-wrapper.properties as follows:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip
