Answer 1

Inside buildscript add google() then open terminal write command-- gradlew build and press enter.

repositories {
    google()
    jcenter()
}

NB: Make sure you are in active network connection

Answer 2

You changed Gradle plugin version, not Gradle version

Set your Gradle Plugin version to 2.3
Then open gradle/wrapper/gradle-wrapper.properties and change Gradle version at line distributionUrl

Answer 3

This version of the gradle plugin doesn't exist.

classpath 'com.android.tools.build:gradle:3.3'

use the latest beta release:

classpath 'com.android.tools.build:gradle:3.0.0-beta6'

Instead if you would like to update gradle, update the distributionUrl in gradle-wrapper.properties.

Answer 4

I updated following line of

code: classpath 'com.android.tools.build:gradle:2.3.3' 
classpath 'com.google.gms:google-services:3.0.0' 

and distributionUrl in gradle-wrapper.properties 'distributionUrl=https\://services.gradle.org/distributions/‌​gradle-3.3-all.zip'

and MOST IMPORTANT is FILE>SETTING>Build,Execution,Deployment>Build Tools>Gradles: Project-level settings: checked :Use default gradle wrapper(recommended)
