Android Studio引用遠程依賴包時下載不了jar包的解決方法

有一個工程使用了遠程的jar包，報錯如下

報錯信息：

               > Remote host closed connection during handshake

原來的build.gradle配置爲：

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

從錯誤信息上可以看出，訪問https://maven.google.com/時Remote host closed connection during handshake（訪問握手期間遠程主機關閉連接），被牆了！

改下，用下面的配置：

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

儘量避免使用靜態的url地址，配置完clean後重新編譯，沒問題了
