近来迁移了一些项目到Android Studio,采用Gradle构建确实比原来的Ant方便许多。但是编译时下载依赖的网速又着实令人蛋疼不已。

如果能切换到国内的Maven镜像仓库,如开源中国的Maven库,又或者是换成自建的Maven私服,那想必是极好的。

一个简单的办法,修改项目根目录下的build.gradle,将jcenter()或者mavenCentral()替换掉即可:

allprojects {
repositories {
maven{ url 'http://maven.oschina.net/content/groups/public/'}
}
}
  • 1
  • 2
  • 3
  • 4
  • 5
  • 1
  • 2
  • 3
  • 4
  • 5

但是架不住项目多,难不成每个都改一遍么? 
自然是有省事的办法,将下面这段Copy到名为init.gradle文件中,并保存到USER_HOME/.gradle/文件夹下即可。

allprojects{
repositories {
def REPOSITORY_URL = 'http://maven.oschina.net/content/groups/public'
all { ArtifactRepository repo ->
if(repo instanceof MavenArtifactRepository){
def url = repo.url.toString()
if (url.startsWith('https://repo1.maven.org/maven2') || url.startsWith('https://jcenter.bintray.com/')) {
project.logger.lifecycle "Repository ${repo.url} replaced by $REPOSITORY_URL."
remove repo
}
}
}
maven {
url REPOSITORY_URL
}
}
}

init.gradle文件其实是Gradle的初始化脚本(Initialization Scripts),也是运行时的全局配置。

如果碰到如下错误,多尝试几次就好了:
