Getting unknown property 'classpath' with Jack compiler for Android

Question

I am trying to compile my project with the next Jack compiler. I just updated Android Studio to 2.2-Beta and my gradle plugin to 2.14.1. Here's my gradle file:

buildscript {
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.0-beta1'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        classpath 'com.github.jacobono:gradle-jaxb-plugin:1.3.6'
    }
}


allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

subprojects { project ->
    if(project.name.endsWith("-schema")) {
        apply plugin: 'com.github.jacobono.jaxb'

        dependencies {
            jaxb 'com.sun.xml.bind:jaxb-xjc:2.2.7-b41'
            jaxb 'com.sun.xml.bind:jaxb-impl:2.2.7-b41'
            jaxb 'javax.xml.bind:jaxb-api:2.2.7'
        }
    }
    }

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

android {
    compileSdkVersion 23

    }

    testOptions {

    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}


dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile(

    compile 'com.squareup.okhttp3:okhttp:3.4.1'
    compile project(':library:android-maps-utils')
}

I get the following error when I sync my project.

Error:Could not get unknown property 'classpath' for task ':app:transformJackWithJackForInstantrunconfigDebug' of type com.android.build.gradle.internal.pipeline.TransformTask.

Using gradlew assembleDebug --stacktrace command to compile:

I've updated gradle and android developer studio to the latest version but I am still having this issue.

Answer 1

Try removing the apply plugin: 'android-apt' as that's a plugin that wont be needed any longer.

You are not using the apt tool, rather the annotationProcessor which is built into Gradle v2.2.0 and up.

PS: Make sure you are replacing "apt" with "annotationProcessor" in your dependencies block as well. You probably wont need classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8' either
