Kotlin: gradle sync error in Android Studio

After adding Kotlin to a module I get the following error when syncing:

Error:null cannot be cast to non-null type org.jetbrains.kotlin.gradle.internal.WrappedVariantData

I added the kotlin plugin to this project. It is an appengine module. I'm running: AS 2.3.2 gradle 3.4 kotlin 1.1.2-3

using these plugins:

apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin'
apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'appengine'
apply plugin: 'idea'

Any ideas?

This is a known bug in the kotlin-kapt plugin. There is a fix in 1.1.3, which is currently in EAP and should be released very soon to stable(June 2017).
