我正在使用 Kotlin 开发原生 Android 应用程序。我实现了一个 Worker 类来运行异步 Web 服务调用。除非我不使用dexguard构建，否则我的工人工作正常。仅使用dexguard 构建我得到以下错误

2021-12-07 18:16:46.085 25839-29600/? E/WM-WorkerFactory: Could not instantiate com.xyz.XYZWorker

这是我的代码，我屏蔽了一些类名，因为它是客户端项目。我用 Hilt 注入用例。

@HiltWorker
class XYZWorker @AssistedInject constructor(
    @Assisted context: Context,
    @Assisted workerParameters: WorkerParameters,
    val someUseCase: SomeUseCase,
    val someUseCase2: SomeUseCase2,
) : CoroutineWorker(context, workerParameters) {
...
}

注入提供的用例

class SomeUseCase @Inject constructor(
   private val someRepo: SomeRepo
) : UseCaseParams<List<SomeDomainEntity>, SomeResponseDomainEntity> {
   ...
}

class MyWorkManagerInitializer : Initializer<WorkManager> {

    override fun create(context: Context): WorkManager {
        val workerFactory = getWorkerFactory(appContext = context.applicationContext)
        val config = Configuration.Builder()
            .setWorkerFactory(workerFactory)
            .build()
        WorkManager.initialize(context, config)
        return WorkManager.getInstance(context)
    }

    override fun dependencies(): MutableList<Class<out Initializer<*>>> = mutableListOf()

    private fun getWorkerFactory(appContext: Context): HiltWorkerFactory {
        val workManagerEntryPoint = EntryPointAccessors.fromApplication(
            appContext,
            WorkManagerInitializerEntryPoint::class.java
        )
        return workManagerEntryPoint.hiltWorkerFactory()
    }

    @InstallIn(SingletonComponent::class)
    @EntryPoint
    interface WorkManagerInitializerEntryPoint {
        fun hiltWorkerFactory(): HiltWorkerFactory
    }
}
