由于 Hilt 错误，应用程序未初始化

Question

由于 Hilt 错误，应用程序未初始化

bin*_*ypv 3 android dependency-injection kotlin dagger-hilt

我正在尝试启动一个小项目，遵循干净的架构、MVVM 并使用 Retrofit、协程等。我使用 Hilt 进行 DI，并且遵循了我在文档和其他项目中看到的大部分内容。

如果我使用 @AndroidEntryPoint 注释我的 Activity 或 Fragment 或使用 @HiltAndroidApp 注释应用程序，则应用程序甚至无法启动。堆栈跟踪对我来说并没有说太多，但也许我跳过了一些东西。如果我不注释类，应用程序会尝试启动，但由于它无法从任何地方注入 ViewModel，因此它显然会崩溃。

Cause: com.example.searchspotify.presentation.view.activity.Hilt_MainActivity

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:transformClassesWithAndroidEntryPointTransformForDebug'.
> javassist.NotFoundException: com.example.searchspotify.presentation.view.activity.Hilt_MainActivity

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:transformClassesWithAndroidEntryPointTransformForDebug'.

我很确定我错过了一些我没有看到的非常基本的东西，因为我不熟悉设置 DI 框架。预先非常感谢。

更新：添加清单以防万一。显现

就我而言，我忘记了我正在使用 Kotlin 并使用了annotationProcessor。我改回 kapt 就没有再出现错误了。
