kapt Build Fails With Dagger Android Processor

android kotlin dagger-2 kapt
Bryan picture Bryan · Apr 27, 2017 · Viewed 38.2k times · Source

I am attempting to include the Dagger Android Processor (documented here) in my project with the Kotlin Annotation Processing Tool (kapt).

I have included the proper dependencies in my build.gradle file:

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

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "com.example.app"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
        exclude group: 'com.google.code.findbugs', module: 'jsr305'
    })

    // Support libraries
    compile "com.android.support:appcompat-v7:25.3.1"
    compile "com.android.support:design:25.3.1"
    compile "com.android.support.constraint:constraint-layout:1.0.2"

    // Google libraries
    compile "com.google.dagger:dagger-android:2.10"
    compile "com.google.dagger:dagger-android-support:2.10"
    kapt "com.google.dagger:dagger-android-processor:2.10"

    // ReactiveX libraries
    compile "io.reactivex.rxjava2:rxandroid:2.0.1"
    compile "io.reactivex.rxjava2:rxjava:2.0.9"

    // Kotlin libraries
    compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:1.1.2"

    // Test instrumentation
    testCompile "junit:junit:4.12"
}

But when I build the project I get the following GradleException:

:app:kaptDebugKotlin FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:kaptDebugKotlin'.
> Internal compiler error. See log for more details

* Try:
Run with --info or --debug option to get more log output.

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:kaptDebugKotlin'.

According to the Kotlin 1.0.4 release changelog:

You should enable [generateStubs] only if you’ve run into problems with the default kapt annotation processing implementation.

Which I tried, but no luck.

Root build.gradle:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.1.2"
        classpath "com.android.tools.build:gradle:2.3.1"
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

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

Bah, I missed part of the error message that was before the break:

:app:kaptDebugKotlin
e: /Users/me/Downloads/App/app/build/tmp/kapt3/stubs/debug/com/example/app/ui/module/main/MainActivityModule.java:10: error: @dagger.android.ActivityKey methods should bind dagger.android.AndroidInjector.Factory<? extends android.app.Activity>, not dagger.android.AndroidInjector.Factory<? super android.app.Activity>.

I was using the in variance annotation instead of the out annotation when creating the AndroidInjector.Factory.

@Module(subcomponents = arrayOf(MainActivitySubcomponent::class))
abstract class MainActivityModule {

    @Binds @IntoMap @ActivityKey(MainActivity::class)
    abstract fun bindMainActivityInjectorFactory(
            builder: MainActivitySubcomponent.Builder): AndroidInjector.Factory<out Activity> // Was using `in` annotation instead of `out`
}
