Dagger-Hilt测试错误-错误:找不到符号@ScopeMetadata，@QualifierMetadata

Question

我正在Android上学习测试，但在使用Dagger-Hilt进行测试时，我出现了以下错误：

> Task :app:kaptDebugAndroidTestKotlin
C:UsersHenriqueDevProjetos-AndroidTestingOnAndroidTutorialappbuildgeneratedsourcekaptdebugAndroidTestcomyoutubetutorialstestingonandroidtutorialdiTestAppModule_ProvideInMemoryDbFactory.java:11: error: cannot find symbol

@QualifierMetadata

symbol: class QualifierMetadata

这个错误是在运行测试时引起的，它发生在Android生成的类中，但我不知道如何解决它，我在互联网上查看了一下，没有发现任何关于这个错误的信息

下面是我的刀和我的测试模块

Answer 1

今天我也遇到了这个错误。我在我的项目中实施了dagger柄。但@ScopeMetaData和@QualifierMetaData是基于dagger的。我解决了这个问题，除了dagger柄：之外，我还添加了dagger依赖项

implementation 'com.google.dagger:dagger:2.41 '
kapt 'com.google.dagger:dagger-compiler:2.41'

Answer 2

我的问题是由于具有不同版本的多个依赖项和不同的依赖项符号，并且我缺少支持库。对于使用Kotlin的Android，我有：

annotationProcessor 'com.google.dagger:dagger-compiler:2.41'
kapt 'com.google.dagger:dagger-compiler:2.41'
annotationProcessor 'com.google.dagger:dagger-android-processor:2.24'
kapt 'com.google.dagger:dagger-android-processor:2.24

应为：

implementation 'com.google.dagger:dagger-android-support:2.41'
kapt 'com.google.dagger:dagger-android-processor:2.41'
kapt 'com.google.dagger:dagger-compiler:2.41'
