Flutter 新项目构建错误 mergeDebugResources

Question

我创建了一个新的 flutter 项目，当我运行默认应用程序时(未进行任何编辑)，它突然出现以下错误。

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:mergeDebugResources'.

我已经尝试了一切!

• 我安装了新版本的 Visual C++，因为有人将其作为解决方案，解决了与我的堆栈溢出问题类似的问题。
• 我安装了新版本的 flutter
• 我安装了新版本的 Java JDK 1.8
• 我更改了 JAVA_HOME 和 ANDROID_HOME 的用户变量

但还是不行。

这是 flutter doctor 的输出:

Doctor summary (to see all details, run flutter doctor -v):
[√] Flutter (Channel stable, 1.22.2, on Microsoft Windows [Version 10.0.18362.1139], locale en-NL)

[√] Android toolchain - develop for Android devices (Android SDK version 30.0.2)
[√] Android Studio (version 4.0)
[√] VS Code (version 1.50.1)
[√] Connected device (1 available)

• No issues found!

我用的是windows。 旧项目确实有效

简而言之，问题是什么？

当我创建新项目时，即使不进行任何更改，默认项目(以及此后所做的所有编辑)都会导致 mergeDebugResources 错误。

有谁知道怎么解决这个问题吗？ 您的帮助将是巨大的支持!

看来是Gradle的问题。来自此线程:https://github.com/flutter/flutter/issues/51690已发布此可能的修复(更新 Gradle 版本)。

在gradle/wrapper/gradle-wrapper.properties中尝试更改:

https\://services.gradle.org/distributions/gradle-5.6.2-all.zip

至

https\://services.gradle.org/distributions/gradle-5.6.3-all.zip

这里还有一个堆栈溢出的答案: https://stackoverflow.com/a/61156603/13714686

其中详细介绍了如何通过更改 Gradle 设置来解决此问题。
