AndroidStudio版本是3.0
到底要怎麼來配置呢？
在C盤的使用者包目錄下的~/.gradle/中新建init.gradle，並輸入如下內容：

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')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_REPOSITORY_URL."
                    remove repo
                }
                if
 
 (url.startsWith('https://jcenter.bintray.com/')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_JCENTER_URL."
                    remove repo
                }
            }
        }
        maven {
            url ALIYUN_REPOSITORY_URL
            url ALIYUN_JCENTER_URL
        }
    }
}
 

不過有的jar包是GitHub上的 則需要

allprojects {
    repositories {
     // 我這是下載com.github.CymChad:BaseRecyclerViewAdapterHelper需要的
        maven {url "https://jitpack.io"}
    }
}
