我试图按照教程构建一个使用 Dagger Hilt 的应用程序。 我在从 API 设置对象列表后检查应用程序是否正常工作，但随后我不断收到以下错误：
java.lang.RuntimeException: Unable to instantiate application com.example.pokedex_tutorial.PokedexApplication: java.lang.ClassNotFoundException: Didn't find class "com.example.pokedex_tutorial.PokedexApplication" on path: DexPathList[[zip file "/data/app/~~dm2RLkrZitO-2YAba3pu3A==/com.example.pokedex_tutorial-4k4KLyudFgSUrCU--HNRXA==/base.apk"],nativeLibraryDirectories=[/data/app/~~dm2RLkrZitO-2YAba3pu3A==/com.example.pokedex_tutorial-4k4KLyudFgSUrCU--HNRXA==/lib/x86, /system/lib, /system_ext/lib]]

我发现对于某些人来说问题源于 gradle 文件，所以这里是：

}如果有人偶然发现类似的问题：问题是 ksp 仍然无法正确支持 hilt。我通过恢复到 kapt 解决了这个问题
