flutter 升级版本后 构建失败 Gradle task assembleDebug failed with exit code 1

• 升级后报错如下

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.
> Could not resolve all task dependencies for configuration ':app:debugCompileClasspath'.
   > Could not resolve io.flutter:flutter_embedding_debug:1.0.0-c9506cb8e93e5e8879152ff5c948b175abb5b997.


// 最后结尾为
BUILD FAILED in 8m 31s
Running Gradle task 'assembleDebug'...
Running Gradle task 'assembleDebug'... Done                       512.5s (!)

• 建议执行下 flutter clean 删除构建文件
• 解决办法 替换以为文件地址为国内地址
  • flutter/packages/flutter_tools/gradle/resolve_dependencies.gradle
  • flutter/packages/flutter_tools/gradle/aar_init_script.gradle
  • flutter/packages/flutter_tools/gradle/flutter.gradle
• storage.googleapis.com/download.fl… 替换为：download.flutter.io 重新编译
