Kapt, Kotlin, Dagger2 Error while annotation processing

Question

I'm getting this gradle error after adding com.google.dagger:dagger-android-support dependency in a project with kotlin.

This is part of my build gradle build.gradle

    apply plugin: 'com.android.application'
    apply plugin: 'kotlin-android'
    apply plugin: 'realm-android'
    apply plugin: 'me.tatarka.retrolambda'
    apply plugin: 'kotlin-kapt'

    android {
      ...
       kapt {
         generateStubs = true
       }
    }
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'
    })

    ...
       kapt "com.google.dagger:dagger-compiler:${daggerVersion}"
       kapt "com.google.dagger:dagger-android-processor:${daggerVersion}"
       compile "com.google.dagger:dagger:${daggerVersion}"
       compile "com.google.dagger:dagger-android-support:${daggerVersion}"

       ...
    }

and here the gradle error that I get

ApplicationComponent.java:21: error: [dagger.android.AndroidInjector.inject(T)] java.util.Map<java.lang.Class<? extends android.support.v4.app.Fragment>,javax.inject.Provider<dagger.android.AndroidInjector.Factory<? extends android.support.v4.app.Fragment>>> cannot be provided without an @Provides-annotated method.

ApplicationComponent

@Singleton
@Component(modules = {AndroidInjectionModule.class, ApplicationModule.class, RetrofitModule.class, ActivityBuilderModule.class})
public interface ApplicationComponent {

    @Component.Builder
    interface Builder {

        @BindsInstance
        Builder application(Application application);

        ApplicationComponent build();
    }

    void inject(TaskApplication application);
}

Anyone had the same problem?

Did you do a clean build? Kotlin with annotation processors still has a few kinks — David Medenjak, Aug 09 '17 at 16:12

Solved by using the AndroidSupportInjectionModule once I'm using android.support.v4.app.Fragment.

@Singleton
@Component(modules = {AndroidSupportInjectionModule.class, ApplicationModule.class, RetrofitModule.class, ActivityBuilderModule.class})
public interface ApplicationComponent {

    @Component.Builder
    interface Builder {

        @BindsInstance
        Builder application(Application application);

        ApplicationComponent build();
    }

    void inject(TaskApplication application);
}

Did you try adding kapt in your app level gradle file?

kapt {
    generateStubs = true
}

this is probably the soultion, see my answer here: https://stackoverflow.com/questions/41213765/issue-with-databinding-using-kotlin-for-android/41220138#41220138 `generateStubs = true` is not allowed with kapt3 (`apply plugin: 'kotlin-kapt'`) – Lovis Aug 10 '17 at 08:28
