解决Android Studio 下载gradle包慢问题

解决Android Studio 下载gradle包慢问题

Android Studio下载包依赖非常慢的原因

因为国内访问bintray、jcenter网站访问速度很慢。默认仓库网站如下：

• https://jcenter.bintray.com/
• https://dl.google.com/dl/android/maven2/

解决方法

使用阿里提供的仓库进行下载依赖包。阿里仓库网站，包含jcenter、maven、Google仓库，网站是 https://developer.aliyun.com/mvn/guide。

在用户目录/.gradle，新建init.gradle，复制以下内容到init.gradle文件。

gradle.projectsLoaded {
    rootProject.allprojects {
        buildscript {
            repositories {
                def JCENTER_URL = 'https://maven.aliyun.com/repository/public'
                def GOOGLE_URL = 'https://maven.aliyun.com/repository/google'
                def NEXUS_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://jcenter.bintray.com/')) {
                            project.logger.lifecycle "Repository ${repo.url} replaced by $JCENTER_URL."
                            println("buildscript ${repo.url} replaced by $JCENTER_URL.")
                            remove repo
                        }
                        else if (url.startsWith('https://dl.google.com/dl/android/maven2/')) {
