Android Studio配置中“Gradle sync failed: SSL peer shut down incorrectly”或者“Read timed out”解决办法

• 原因
  gradle同步过程中网络问题容易导致中断，挂了梯子也可能出现问题

• 解决
  使用阿里云镜像

  修改build.gradle文件成如下：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        //google()
        //jcenter()
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/repository/google/'}
        maven { url 'https://maven.aliyun.com/repository/jcenter/'}
        mavenLocal()
        mavenCentral()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.0.0"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        //google()
        //jcenter()
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/repository/google/'}
        maven { url 'https://maven.aliyun.com/repository/jcenter/'}
        mavenLocal()
        mavenCentral()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
