采用Gradle有时需要下载外网的依赖，存在下载不到的情况，因此这里记录一下解决方式，将init.gradle文件放置在如下文件夹：

C:\Users\User-Name\.gradle

文件内容

allprojects{
    repositories {
        def ALIYUN_CENTRAL_URL = 'https://maven.aliyun.com/repository/central'
        def ALIYUN_JCENTER_URL = 'https://maven.aliyun.com/repository/public'

        def ALIYUN_APACHE_SNAPSHOT_URL = 'https://maven.aliyun.com/repository/apache-snapshots'

        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."
