原因是国内访问jcenter太慢,甚至连接不上,就会报各种关于依赖更新失败的错误。
以前oschina(也就是开源中国)提供了jcenter的镜像地址,然而不幸的是因为各种原因,最近停止服务了
幸运的是阿里云提供了jcenter镜像 http://maven.aliyun.com/
可以在工程gradle中如下修改,加速gradle sync
Gradle代码
- // 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/groups/public'}
- //jcenter()
- }
- dependencies {
- classpath 'com.android.tools.build:gradle:2.2.2'
- // 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/groups/public'}
- //jcenter()
- }
- }
