我应该如何解决这个问题，因为我的构建被阻止为 --> 失败：构建因异常而失败？

Question

here's the code with the error
失败：构建失败，出现异常。

其中：
脚本“/home/patto/flutter/packages/flutter_tools/gradle/flutter.gradle”行：793

我今天遇到了同样的问题。

我通过

修复了它

flutter upgrade

然后

flutter doctor

当我运行我的 Flutter 应用再次运行时，错误消失了。

这是我对 flutter doctor 的输出：

Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, 1.20.1, on Linux, locale en_US.UTF-8)
 
[✓] Android toolchain - develop for Android devices (Android SDK version 30.0.0)
[✓] Android Studio (version 4.0)

如您所见，它再次构建了 flutter 工具，并可能通过这样做修复了它。

我应该如何解决这个问题，因为我的构建被阻止为 --> 失败：构建因异常而失败？

How should I workaround this since my build is being blocked as -->FAILURE: Build failed with an exception?
