Missing annotation processing in Android Studio

Question

I'm using Android Studio 2.2.3 and build tools 24.0.2.

Several of the libraries, including Butterknife use annotations in build.gradle for the app I'm trying to compile. On the first I get this error:

Gradle sync failed: Could not find method annotationProcessor() for arguments [com.jakewharton:butterknife-compiler:8.4.0]

At the AS start up window I've edited the preferences and ticked Annotation Processing. I cleared the caches and restarted Android. Still getting that error.

App level build.gradle:

buildscript {
    repositories {
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'
        classpath 'com.github.triplet.gradle:play-publisher:1.1.4'
        //noinspection GradleDynamicVersion
        classpath 'io.fabric.tools:gradle:1.+'
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
    }
}

task wrapper(type: Wrapper) {
    gradleVersion = '3.1'
    distributionUrl = distributionUrl.replace("bin", "all")
}

The butterknife page asks to include this line :

annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'

Did you include that in your app level gradle?
