gradle下载超时

今天本来想学习一下spring源码的, 结果编译时一直失败, 检查发现下载资源超时

 查看网上资料, 发现可能是网络问题, 需要修改到国内镜像

方法一

找到项目的build.gradle文件, 添加镜像

repositories {
        google()
        jcenter()
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter'}
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/google'}
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/gradle-plugin'}

        mavenCentral()
}



allprojects {
	repositories {
		maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}
		mavenCentral()
	}
}

方法二

找到在settings>>build>>build tools>>gradle找到.gradle目录, 向其添加init.gradle文件

添加如下内容:

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
        }
    }
}
