更新flutter之后，flutter run报错

更新flutter之后，新建项目，运行flutter run，出现错误。

Sending crash report to Google. Failed to send crash report due to a
network error: SocketException: OS Error: 信号灯超时时间已到 , errno = 121,
address = clients2.google.com, port = 27630

配置一下更新服务器地址，build.gradle文件内修改成国内镜像：

google()
// jcenter()
maven{ url ‘https://maven.aliyun.com/repository/google’ }
maven{ url ‘https://maven.aliyun.com/repository/jcenter’ }
maven{url ‘http://maven.aliyun.com/nexus/content/groups/public’}

在项目目录下生成的错误日志提示：

please let us know at https://github.com/flutter/flutter/issues.

发现是这个压缩包出错，去重新下载gradle-4.10.2-all.zip。然后替换掉文件，再执行flutter run正常了。
