在 flutter 中运行应用程序时，任务 ':app:cleanMergeDebugAssets' 的执行失败

Question

在 Visual Studio Code v1.46.1 中运行应用程序时出现主要错误

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:cleanMergeDebugAssets'.
> Unable to delete directory 'E:\ACNO\Flutter\jots_mobile\build\app\intermediates\merged_assets\debug\out'
    Failed to delete some children. This might happen because a process has files open or has its working directory set in the target directory.
    - E:\ACNO\Flutter\jots_mobile\build\app\intermediates\merged_assets\debug\out\flutter_assets\assets
    - E:\ACNO\Flutter\jots_mobile\build\app\intermediates\merged_assets\debug\out\flutter_assets\packages\cupertino_icons
    - E:\ACNO\Flutter\jots_mobile\build\app\intermediates\merged_assets\debug\out\flutter_assets\packages

Exited (sigterm)

此错误在之后得到解决，flutter clean但即使显示以下错误

下面是输出 flutter clean

即使我终止了本答案中提到的使用build和.dart_tool文件夹的进程，也会显示相同的错误flutter clean

所以，现在我必须手动转到文件资源管理器并删除build和.dart_tool文件夹，这是这里的主要问题！

总结：运行应用程序时的主要错误得到解决，flutter clean但即使这样也显示错误，所以现在我必须手动删除build和.dart_tool文件夹！

问：如何解决这些问题？

更新：刚刚注意到这个错误发生在我使用“f5”在 VS 代码中运行我的程序时而不是当我flutter run在终端或 Android Studio 中使用命令时，但是一旦它发生在“f5”上，它就会发生在flutter run命令和 Android 上工作室两者。我猜 VS Code 中启用此“f5”快捷方式的扩展程序有问题！

问题在于 VS Code 中的 Kotlin 插件，因此删除它应该可以解决我们的问题！

现在我可以在调试模式下运行项目。下面是我的颤振医生

Doctor summary (to see all details, run flutter doctor -v):
[?] Flutter (Channel stable, v1.17.4, on Microsoft Windows [Version 10.0.17763.1282, locale en-MY)

[?] Android toolchain - develop for Android devices (Android SDK version 29.0.3)
[?] Android Studio (version 4.0)
[?] VS Code (version 1.46.1)
[?] VS Code, 64-bit edition (version 1.46.1)
[?] Connected device (1 available)

我在 VS Code 中重新安装了 Kotlin 插件，问题又回来了。我删除了它，项目运行。所以我猜是插件。我使用和删除的插件是Kotlin 0.2.17

任何人都可以仔细检查问题是否是因为这个？
