linux nexus 配置使用

1. 仓库类型
   proxy:代理仓库，用于代理远程仓库 ，负责打通私服与远程仓库之间的通道。
   group:仓库组，通常包含了多个代理仓库和宿主仓库，在项目中只要引入仓库组就可以下载到代理仓库和宿主仓库中的包
   hosted:宿主仓库，内部项目、付费jar
   releases 发布内部release版本的仓库
   snapshots 发布内部snapshots版本的仓库
   third 自建第三方jar

   maven下载依赖过程：

   

2. 配置代理
   
   选择阿里云http://maven.aliyun.com/nexus/content/groups/public/
3. 本地maven配置
   修改maven目录下的conf/setting.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">
   <pluginGroups/>
   <proxies/>
   <servers>
   <server>
     <id>xdclass-releases</id>
     <username>admin</username>
     <password>admin123</password>
   </server>
   <server>
     <id>xdclass-snapshots</id>
     <username>admin</username>
     <password>admin123</password>
   </server>
   </servers>
   <mirrors/>
   <profiles>
   <profile>
     <id>xdclass</id>
     <activation>
       <activeByDefault>false</activeByDefault>
     </activation>
     <!-- 私有库地址-->
     <repositories>
       <repository>
         <id>xdclass</id>
         <url>http://192.168.56.101:8081/repository/maven-public/</url>
         <releases>
           <enabled>true</enabled>
         </releases>
         <snapshots>
           <enabled>true</enabled>
         </snapshots>
       </repository>
     </repositories>
     <!--插件库地址-->
     <pluginRepositories>
       <pluginRepository>
         <id>xdclass</id>
         <url>http://192.168.56.101:8081/repository/maven-public/</url>
         <releases>
           <enabled>true</enabled>
         </releases>
         <snapshots>
           <enabled>true</enabled>
         </snapshots>
       </pluginRepository>
     </pluginRepositories>
   </profile>
   </profiles>
   <activeProfiles>
   <activeProfile>xdclass</activeProfile>
   </activeProfiles>
   </settings>

4. 修改IDEA中maven的配置，将配置指向setting.xml

5. 修改pom

   <!--pom.xml 远程仓库的配置  id要跟本地maven的setting.xml相同 -->
   <distributionManagement>
       <repository>
           <id>xdclass-releases</id>
           <name>Ruizhi Release Repository</name>
           <url>http://192.168.56.101:8081/repository/maven-releases/</url>
       </repository>
   
       <snapshotRepository>
           <id>xdclass-snapshots</id>
           <name>Ruizhi Snapshot Repository</name>
           <url>http://192.168.56.101:8081/repository/maven-snapshots/</url>
       </snapshotRepository>
   </distributionManagement>

6. 测试是否nexus搭建成功
   pom添加本地没有的依赖，看nexus会不会代理
   mvn deploy 看是否成功推送至nexus
