allprojects {
    repositories {
        maven { url 'file:///D:/repository'}
        mavenLocal()
        maven { name "Alibaba" ; url "https://maven.aliyun.com/repository/public" }
        maven { name "Bstek" ; url "http://nexus.bsdn.org/content/groups/public/" }
        mavenCentral()
    }

    buildscript { 
        repositories { 
            maven { name "Alibaba" ; url 'https://maven.aliyun.com/repository/public' }
            maven { name "Bstek" ; url 'http://nexus.bsdn.org/content/groups/public/' }
            maven { name "M2" ; url 'https://plugins.gradle.org/m2/' }
        }
    }
}

• 或者添加以下内容

allprojects{
    repositories {
        def REPOSITORY_URL = 'http://maven.aliyun.com/nexus/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
                }
            }
