解决gradle下载慢的问题

到~/.gradle/目录下创建一个 init.gradle 文件，把下面这些复制进去就 ok 了
allprojects{
repositories {
def ALIYUN_REPOSITORY_URL = ‘http://maven.aliyun.com/nexus/content/groups/public‘
def ALIYUN_JCENTER_URL = ‘http://maven.aliyun.com/nexus/content/repositories/jcenter‘
all { ArtifactRepository repo ->
if(repo instanceof MavenArtifactRepository){
def url = repo.url.toString()
if (url.startsWith(‘https://repo1.maven.org/maven2‘) || url.startsWith(‘http://repo1.maven.org/maven2‘)) {
project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_REPOSITORY_URL."
remove repo
}
if (url.startsWith(‘https://jcenter.bintray.com/‘) || url.startsWith(‘http://jcenter.bintray.com/‘)) {
