Android Studio 更新同步Gradle错误解决方法

1、在https://services.gradle.org/distributions/下载对应的gradle的zip包，对应方法见gradle-wrapper.properties文件中的：

distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

将zip包放置于诸如“C:\Users\Administrator\.gradle\wrapper\dists\gradle-4.4-all\9br9xq1tocpiv8o6njlyu5op1”目录下

2、修改build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()
        maven { url 'https://jitpack.io' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'

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

allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'https://jitpack.io' }
    }
}

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

3、修改setting

mirrors.dormforce.net

4、也可以通过本地m2文件方式

在http://mirrors.neusoft.edu.cn/android/repository/

下载m2仓库：android_m2repository_r47.zip
将Android目录放入.m2目录

比如

• C:\Users\Administrator\.m2\repository\
• C:\Program Files\Android\Android Studio\gradle\m2repository\com\android

gradle实际上会先把依赖存放在cache中，读取也先从cache中读取，比如：
