将 Koin 升级到 3.1.3 时，使用 sharedViewModel 的 Android 测试失败并出现 java.lang.ClassCastException androidx.lifecycle.SavedStateHandleController

Question

我目前正在使用 Koin 版本 3.1.0 并想升级到最新版本(当前为 3.1.4)，但是一旦我将 Koin 升级到 3.1.3 以上，我在运行测试时会遇到以下异常:

class java.lang.Object cannot be cast to class androidx.lifecycle.SavedStateHandleController (java.lang.Object is in module java.base of loader 'bootstrap'; androidx.lifecycle.SavedStateHandleController is in unnamed module of loader org.robolectric.internal.AndroidSandbox$SdkSandboxClassLoader @5c2a3b10)

我注意到它与 sharedViewModel 有关-extension 当我将某些事件更改为 by viewModel() 时导致测试将成功。但是，这种解决方法是 Not Acceptable ，因为我需要共享的 ViewModel。
有没有人可以解决这个问题？

将您的 koin 版本降级为 2.2.3应该修复它!
