我的 Flutter 项目今天构建失败，出现以下错误:

Where: Build file 'D:\Dev\Flutter\Projects\Misc\flutter_app\android\app\build.gradle' line: 26

What went wrong: A problem occurred evaluating project ':app'.

Could not resolve all artifacts for configuration 'classpath'. Could not find aapt2-proto.jar (com.android.tools.build:aapt2-proto:0.3.1). Searched in the following locations: https://jcenter.bintray.com/com/android/tools/build/aapt2-proto/0.3.1/aapt2-proto-0.3.1.jar

我还在 Android Studio 中启动了一个全新的 Flutter 项目，没有进行任何更改，并且得到了同样的错误。

我在 Windows 10 64 位上运行 Android Studio 3.2.1(10 月 9 日)。

这是我的 Flutter 医生输出:

> D:\Dev\Flutter\Flutter\bin\flutter.bat --no-color doctor Doctor

(忽略 Flutter 和 Dart 插件未安装警告，尽管一切正常，但它们始终在我身边)

我试过其他的suggestions例如确保 google() 存储库位于 Gradle 构建文件之上，但没有运气。

最佳答案

文件中缺少 google():flutter/packages/flutter_tools/gradle/flutter.gradle#L21

合并后应该解决https://github.com/flutter/flutter/pull/23397
