Android studio Gradle编译错误： Unable to tunnel through proxy. Proxy returns "HTTP/1.1 400 Bad Reques

两种处理方法：

1.修改distributionUrl链接

gradle-wrapper.properties文件

 distributionUrl=https://services.gradle.org/distributions/gradle-3.3-all.zip

改成

 distributionUrl=http://services.gradle.org/distributions/gradle-3.3-all.zip

2.修改成use local gradle distribution
