有一个工程使用了远程的jar包，报错如下

报错信息：

               > Remote host closed connection during handshake

原来的build.gradle配置为：

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
}

从错误信息上可以看出，访问https://maven.google.com/时Remote host closed connection during handshake（访问握手期间远程主机关闭连接），被墙了！

改下，用下面的配置：

allprojects {
    repositories {
        jcenter()
        mavenCentral()
        google()
    }
}

尽量避免使用静态的url地址，配置完clean后重新编译，没问题了
