java - Dagger Hilt 测试错误 - 错误 : cannot find symbol @ScopeMetadata, @QualifierMetadata

Question

我正在研究 Android 上的测试，但是在使用 Dagger Hilt 进行测试时，出现以下错误:

> Task :app:kaptDebugAndroidTestKotlin
C:\Users\Henrique\Dev\Projetos-Android\TestingOnAndroidTutorial\app\build\generated\source\kapt\debugAndroidTest\com\youtube\tutorials\testingonandroidtutorial\di\TestAppModule_ProvideInMemoryDbFactory.java:11: error: cannot find symbol
@ScopeMetadata
 ^
  symbol: class ScopeMetadata
C:\Users\Henrique\Dev\Projetos-Android\TestingOnAndroidTutorial\app\build\generated\source\kapt\debugAndroidTest\com\youtube\tutorials\testingonandroidtutorial\di\TestAppModule_ProvideInMemoryDbFactory.java:12: error: cannot find symbol
@QualifierMetadata
 ^
  symbol: class QualifierMetadata
C:\Users\Henrique\Dev\Projetos-Android\TestingOnAndroidTutorial\app\build\generated\source\kapt\debugAndroidTest\com\youtube\tutorials\testingonandroidtutorial\data\local\ShoppingDaoTest_MembersInjector.java:10: error: cannot find symbol
@QualifierMetadata
 ^
  symbol: class QualifierMetadata

此错误是在运行测试时引起的，它发生在由 Android 生成的类中，但我不知道如何解决它，我在互联网上查看并没有发现有关此错误的任何信息

Answer 1

今天我也遇到了这个错误。我在我的项目中实现了 Dagger 。但是@ScopeMetaData 和@QualifierMetaData 是基于 Dagger 的。
除了 dagger-hilt 之外，我还通过添加 dagger 依赖项解决了这个问题:

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