Gradle DSL method not found: 'apt()'

Question

I am trying to add the latest version of butterknife and I get this error from gradle:

Error:(31, 0) Gradle DSL method not found: 'apt()' Possible causes:
The project 'MyProject' may be using a version of Gradle that does not contain the method. Gradle settings
The build file may be missing a Gradle plugin. Apply Gradle plugin

Where my gradle mobile build.gradle is:

plugins {
    id "net.ltgt.apt" version "0.6"
}

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.mynamspace.myproject"
        minSdkVersion 19
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    wearApp project(':wear')
    testCompile 'junit:junit:4.12'
    compile 'com.jakewharton:butterknife:8.0.0'
    apt 'com.jakewharton:butterknife-compiler:8.0.0'
    compile 'com.android.support:appcompat-v7:23.3.0'
    compile 'com.google.android.gms:play-services:8.4.0'
    compile 'com.android.support:design:23.3.0'
    compile 'com.android.support:support-v4:23.3.0'
    compile 'com.android.support:recyclerview-v7:23.3.0'
}

What's wrong with the gradle-apt-plugin?

I haven't seen that `plugins` syntax before, and that does not appear to be the `android-apt` plugin. — CommonsWare, Apr 26 '16 at 21:35
That's the new mecanism of gradle plugins: https://plugins.gradle.org/plugin/net.ltgt.apt (look for the "About the new plugin mechanism"). — Michel Feinstein, Apr 26 '16 at 21:40
Where do I get the `android-apt` plugin?...I confess I am a bit lost here, I don't know much about gradle, I just got this plugin in a google search for "gradle apt" — Michel Feinstein, Apr 26 '16 at 21:41

It's entirely possible that there's a way to get your plugins to work. Given your error, I'd start by following what the ButterKnife project uses, get that working, then see if there is a recipe for what you're trying.

First, in your top-level build.gradle file, include classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8' in the buildscript dependencies, such as:

  buildscript {
    repositories {
      mavenCentral()
    }
    dependencies {
      classpath 'com.android.tools.build:gradle:2.0.0'
      classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    }
  }

Then, in your module's build.gradle file, include apply plugin: 'com.neenbedankt.android-apt' towards the top.

The links are to the relevant files from the ButterKnife GitHub repo, from the project and the dedicated sample app.

Thanks for the help! The project's page (http://jakewharton.github.io/butterknife/) have these configurations missing.....but the github page doesnt (https://github.com/JakeWharton/butterknife) and they are pretty much the same as your code. – Michel Feinstein Apr 26 '16 at 23:09

Coming from ButterKnife 7.0.1 to 8.0.1 - the upgrade was not at all obvious. All these extra Gradle entries were not explained very well at all. Finally have it working now thanks to your advice, @CommonsWare! – Matthew Housser May 16 '16 at 22:15
`apply at top` did it – m02ph3u5 Jun 01 '16 at 14:36

apt is obsolete, Change apt to new format:

change

apt 'com.jakewharton:butterknife-compiler:8.5.1'

to

annotationProcessor 'com.jakewharton:butterknife-compiler:8.5.1'

Instead of:

    plugins {id "net.ltgt.apt" version "0.6"}

try:

    apply plugin: 'android-apt'

In my case helped: adding to your build.gradle (not main, but project one) :

apply plugin: 'com.neenbedankt.android-apt'

and

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.7'
    }
}

Add your apt code into the apps build.gradle NOT in main build.gradle.

dependencies {
    apt group: 'group name here', name: 'artifact name here', version:'version here'
}

Of Course, you'll have to add the following code in your main build.gradle

buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.2'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    }
}
