方案一：切换镜像仓库 （原文地址）
阿里的仓库地址（亲测有效）：http://maven.aliyun.com/nexus/content/groups/public/
OSChina的仓库地址：http://maven.oschina.net/content/groups/public/
// Top-level build file where you can add configuration options common to all sub-projects/modules.buildscript {
repositories {
maven{ url 'http://maven.aliyun.com/nexus/content/repositories/central/'}
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'// NOTE: Do not place your application dependencies here;
they belong
// in the individual module build.gradle files
}
}allprojects {
repositories {
maven{ url 'http://maven.aliyun.com/nexus/content/repositories/central/'}
google()
jcenter()
}
}task clean(type: Delete) {
delete rootProject.buildDir
}以上方法下载有时会下载不了，替换后如下：
// Top-level build file where you can add configuration options common to all sub-projects/modules.buildscript {
repositories {
//maven{ url 'http://maven.aliyun.com/nexus/content/repositories/central/'}
//maven()
maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'// NOTE: Do not place your application dependencies here;
they belong
// in the individual module build.gradle files
}
}allprojects {
repositories {
//maven{ url 'http://maven.aliyun.com/nexus/content/repositories/central/'}
//maven()
maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
google()
jcenter()
}
}task clean(type: Delete) {
delete rootProject.buildDir
}方案二：更换本地Gradle 【Gradle:Download https:// jcenter.bintray.com/ 下载缓慢解决方法】（原文地址）
