Flutter中任务'：app：mergeDebugResources'的执行失败

Question

我是Flutter的新手，我只是想第一次进行设置。我一直在尝试运行每个新项目随附的演示应用程序，但是Android Studio返回此错误：

FAILURE: Build failed with an exception.

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

我尝试手动（离线）并在连接到互联网的同时安装Gradle。但它似乎没有下载所需的.pom文件。我什至尝试手动下载.pom文件，希望找到如何手动将它们放入Flutter项目中，但是链接（我从控制台复制）将我带到“错误404”页面。

这是我的flutter doctor结果：

我没有启用代理设置。我试图找到解决此问题的方法，但没有在任何地方找到答案。

我也遇到过这个问题。我所做的只是将我的计算机和设备连接到互联网，问题就解决了。我希望这有效..
