# 默认仓库

• maven-central：中央仓库，默认从 https://repo1.maven.org/maven2/ 拉取 jar
• maven-releases：私库发行版 jar（建议将 Deployment policy 设置为 Allow redeploy）
• maven-snapshots：私库调试版 jar
• maven-public：仓库分组，把上面三个仓库组合在一起对外提供服务

# 仓库类型说明

• group：仓库组。内部设置了多个仓库，访问顺序取决于配置顺序（默认为 releases > snapshots > central）
• hosted：私有仓库。内部项目的发布仓库，存储自己生成的 jar
• proxy：代理仓库，从远程中央仓库中寻找数据

# 添加阿里云代理仓库

http://maven.aliyun.com/nexus/content/groups/public

加入 maven-public
