Maven

全局配置

修改 Maven 默认的全局配置文件:

  • 类 Unix 系统： Mac OS / Linux 默认在 ~/.m2/settings.xml
  • Windows 系统：一般在 Maven 安装目录的 conf/settings.xml 
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

    <!-- 添加以下这段 Mirror 配置 -->
    <mirrors>
        <!-- Aliyun -->
        <mirror>
            <id>aliyunmaven</id>
            <name>aliyun maven</name>
            <mirrorOf>*</mirrorOf>      
            <url>https://maven.aliyun.com/repository/public</url>
        </mirror>
    </mirrors>


</settings>

单项目配置

修改项目的 pom.xml，添加以下内容：

<repositories>
    <repository>
        <id>aliyunmaven</id>
        <url>https://maven.aliyun.com/repository/public</url>
    </repository>
</repositories>

Gradle

全局配置

在 ${USER_HOME}/.gradle/ 目录下创建 init.gradle 文件，添加以下内容： 

allprojects {
    repositories {
        def ALIYUN_REPOSITORY_URL = 'https://maven.aliyun.com/repository/public'
        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
                }
            }
        }
        maven { url ALIYUN_REPOSITORY_URL }
    }
}

单项目配置

修改项目的 build.gradle 文件，添加以下内容：

buildscript {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public' }
    }
}

allprojects {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public' }
    }
}

也可以直接添加在 repositories 内：

repositories {
    maven { url 'https://maven.aliyun.com/repository/public' }
    mavenCentral()
}

其他仓库

在上面的配置中，我们主要配置的是 public 仓库，而 阿里云: https://maven.aliyun.com 除此之外，还代理了许多其他的仓库，可作为下载源。如 google、spring 等（更多可点进链接查看详情）。

而我们常用的 public 仓库，其实是 central: https://repo1.maven.org/maven2/ 仓库和 jcenter: http://jcenter.bintray.com/ 仓库的聚合，所以配置了 public 仓库，就不需要再配置 jcenter 的仓库了。

若需要使用其他的代理仓库，如 google、spring，可参考以下配置：

Maven

全局配置

同上，修改 settings.xml 文件：

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

    <mirrors>
        <!-- Aliyun -->
        <mirror>
            <id>alimaven-public</id>
            <name>aliyun public maven repo</name>
            <url>https://maven.aliyun.com/repository/public</url>
            <mirrorOf>*</mirrorOf>
        </mirror>

        <mirror>
            <id>alimaven-google</id>
            <name>aliyun google maven repo</name>
            <url>https://maven.aliyun.com/repository/google</url>
            <mirrorOf>*</mirrorOf>
        </mirror>

        <mirror>
            <id>alimaven-spring</id>
            <name>aliyun spring maven repo</name>
            <url>https://maven.aliyun.com/repository/spring</url>
            <mirrorOf>*</mirrorOf>
        </mirror>

        <!-- Tencent Cloud -->
        <!-- <mirror>
            <id>nexus-tencentyun</id>
            <mirrorOf>*</mirrorOf>
            <name>Nexus tencentyun</name>
            <url>http://mirrors.cloud.tencent.com/nexus/repository/maven-public/</url>
        </mirror> -->

        <!-- Netease 163 -->
        <!-- <mirror>
            <id>netease</id>
            <mirrorOf>*</mirrorOf>
            <name>Netease maven</name>
            <url>http://mirrors.163.com/maven/repository/maven-public/</url>
        </mirror> -->
    </mirrors>


</settings>

单项目配置

修改 pom.xml：

<repositories>
    <repository>
        <id>aliyunmaven-google</id>
        <name>aliyun google maven repo</name>
        <url>https://maven.aliyun.com/repository/google</url>
        <layout>default</layout>
        <!-- 是否开启 release 版构件下载 -->
        <releases>
            <enabled>true</enabled>
        </releases>
        <!-- 是否开启 snapshot 版构件下载 -->
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
    <repository>
        <id>aliyunmaven-spring</id>
        <name>aliyun spring maven repo</name>
        <url>https://maven.aliyun.com/repository/spring</url>
    </repository>
</repositories>

是否开启 releases、snapshots 版下载可根据自身需求调整。

Gradle

全局配置

allprojects {
    repositories {
        def ALIYUN_REPOSITORY_URL = 'https://maven.aliyun.com/repository/public'
        def ALIYUN_GOOGLE_URL = 'https://maven.aliyun.com/repository/google'
        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 $ALIYUN_REPOSITORY_URL."
                    remove repo
                }
                if (url.startsWith('https://dl.google.com/dl/android/maven2')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_GOOGLE_URL."
                    remove repo
                }
            }
        }
        maven { url ALIYUN_REPOSITORY_URL }
        maven { url ALIYUN_GOOGLE_URL }
    }
}

单项目配置

修改 `build.gradle`：

buildscript {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/spring' }
    }
}

allprojects {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/spring' }
    }
}

其他镜像源

腾讯云

https://mirrors.cloud.tencent.com

参考配置：

Maven

 <mirror>
     <id>nexus-tencentyun</id>
     <mirrorOf>*</mirrorOf>
     <name>Nexus tencentyun</name>
     <url>http://mirrors.cloud.tencent.com/nexus/repository/maven-public/</url>
 </mirror> 

<repositories>
    <repository>
        <id>nexus-tencentyun</id>
        <name>Nexus tencentyun</name>
        <url>http://mirrors.cloud.tencent.com/nexus/repository/maven-public/</url>
    </repository>
</repositories>

Gradle

buildscript {
    repositories {
        maven { url 'http://mirrors.cloud.tencent.com/nexus/repository/maven-public/' }
    }
}

allprojects {
    repositories {
        maven { url 'http://mirrors.cloud.tencent.com/nexus/repository/maven-public/' }
    }
}

FAQ

Q: 为什么你配置里用的 URL 都是 https://maven.aliyun.com/repository/public，而我看其他的人/文章，都用的是 http://maven.aliyun.com/nexus/content/groups/public 呢？

A: 阿里云在前几年对 https://maven.aliyun.com 进行了代码和架构上的改造，新版的 https://maven.aliyun.com 下载速度更快，支持高并发，而且全站进行了 HTTPS 加密，更安全。而新版的 Maven Mirror 地址，就是 https://maven.aliyun.com/repository/{reponame}，然而阿里云为了保持旧地址的兼容，所以旧地址依然可以使用，但推荐使用新地址。
