AndroidStudio新建工程gradle编译报Connec

Android studio新版本创建项目后项目的build.gradle配置发生了改变，allproject配置移动到settings.gradle中，用dependencyResolutionManagement替代，如下：

旧版本build.gradle：

...
allprojects {
    repositories {
        mavenCentral()
        google()
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
        maven { url "https://jitpack.io" }
        maven {url "http://maven.aliyun.com/nexus/content/repositories/releases"}
    }
}
...

新版本删除了allprojects项，在settings.gradle中新增如下：

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        jcenter() // Warning: this repository is going to shut down soon
    }
}

工程新建完成后，自动运行会发现报如下错误：

解决方案：
在主工程的build.gradle,添加如下：

buildscript {
    repositories {
//        google()
//        mavenCentral()

        maven { url 'https://plugins.gradle.org/m2/' } //复制这行
        maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' } //复制这行
        maven { url 'https://maven.aliyun.com/nexus/content/groups/public' } //复制这行
        maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter'} //复制这行
    }
    ......
}

在settings.gradle中添加如下内容：

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
//        google()
//        mavenCentral()
//        jcenter() // Warning: this repository is going to shut down soon
        maven { url 'https://plugins.gradle.org/m2/' } //复制这行
        maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' } //复制这行
        maven { url 'https://maven.aliyun.com/nexus/content/groups/public' } //复制这行
        maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter'} //复制这行
    }
}
