Android Studio modifies your build.gradle adding apply plugin: 'kotlin-android' above apply plugin: 'com.android.application'. Just move the Kotlin line below the Android one and Gradle will run smoothly. It should look like this example:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'

This is the correct order for above extension issue. 

 apply plugin: 'com.android.application'
 apply plugin: 'kotlin-android'
