修改 Maven 默认的全局配置文件:
<?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"> <!-- 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>
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>
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 } } }
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() }
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：
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>
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。
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 } } }
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‘ } } }
https://mirrors.cloud.tencent.com
参考配置：
<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>
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/‘ } } }
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。
