Kotlin 1.0.4によると release changelog :
[
generateStubs
]を有効にする必要があるのは、デフォルトのkapt
アノテーション処理の実装で問題が発生した場合のみです。
私は試しましたが、運はありません。
ルート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
}
ああ、休憩前のエラーメッセージの一部を見逃しました。
: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>.

AndroidInjector.Factory
を作成するときに、in
アノテーションの代わりにout
分散アノテーションを使用していました。
@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`
}
問題はkotlin-stdlib-jre7に関連していると思います。短剣では正常に動作しません。これを変更することをお勧めしますkotlin-stdlib-jre7 for- kotlin-stdlib:
compile "org.jetbrains.kotlin:kotlin-stdlib:1.1.2"
の代わりに:
compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:1.1.2"
わたしにはできる。
このビルドが失敗する理由は1つだけではありません。 kotlinにも常に関連しているわけではありません。
原因に関する明確な情報については、Android studioのGradle Consoleでログを確認してください。失敗の手がかりを見つけることができます。
私は同じ問題を経験しました。 build.gradleから離陸しなければなりませんでした。
apply plugin: 'kotlin-kapt'
kapt 'groupId:artifactId:$kapt_version'
そして、私はこれを追加しました(適用プラグの直後:...):
kapt {
generateStubs = true
}
これが他の誰かに役立つことを願っています。
最近Android Studio 3.5(Project Marble)にアップグレードした人-このエラーが表示された場合(特に、多くのモジュールを持つプロジェクトで、ツールバーを使用してプロジェクトをクリーニング、作成、再構築した後でも)、
他の回答を試す前に、Android Studio内の端末から./gradlew assembleDebug
または./gradlew kaptDebugKotlin
を実行し、shouldで問題を修正しますbuild.gradle
を変更する必要があります。
./gradlew
が「コマンドが見つかりません」と表示されている場合は、コメントセクション here を見て解決してください。
./gradlew assembleDebug --info
は、物事があなたにとって同じ方法でうまくいかない場合のための別のオプションでもあり、「info」フラグはあなたに詳細を表示します。
私は多くの方法を試しましたが、次の日追加した後、エラーメッセージは意味がありませんでした
MoviesViewModel @Inject constructor(private val movieService: MovieService): ViewModel()
then :)
