Maven私服Nexus的搭建和使用(Mac)

1.下载对应的安装包 https://www.sonatype.com/oss-thank-you-mac-tgz
注意：目前的版本有2.X 和 3.X ，2.X的支持对Maven更友好一点，3.X的支持范围更广，支持ruby和docker。如果单纯的maven私服，建议使用2.x

2.解压安装包，并进入对应的bin目录下启动nexus
./nexus start

注意：3.X要求JDK的版本在1.8以上

3.访问地址，3.x默认是127.0.0.1:8081 2.x默认是127.0.0.1:8081/nexus ,默认的登陆账户密码为admin/admin123
修改端口或者密码，在etc下的nexus-default.properties

4.简单介绍一下Repository

Repository的type属性有：proxy，hosted，group三种。
proxy：即你可以设置代理，设置了代理之后，在你的nexus中找不到的依赖就会去配置的代理的地址中找
hosted：你可以上传你自己的项目到这里面
group：它可以包含前面两个，是一个聚合体。一般用来给客户一个访问nexus的统一地址。
简单的说，就是你可以上传私有的项目到hosted，以及配置proxy以获取第三方的依赖（比如可以配置中央仓库的地址）。前面两个都弄好了之后，在通过group聚合给客户提供统一的访问地址

5.如何上传jar包
先设置settings.xml,这里主要是配置用户名和密码，注意这里的id要和respositoryId对应

<servers>

      <server>

       <id>nexus</id>

       <username>admin</username>

       <password>admin123</password>

    </server>

</servers>

控制台
mvn deploy:deploy-file -DgroupId=ebay -DartifactId=ebay -Dversion=0.0.1-SNAPSHOT -Dpackaging=jar  -Dfile=/Users/yuliangliang/ebay-0.0.1-SNAPSHOT.jar -Durl=http://localhost:8081/repository/maven-snapshots/ -DrepositoryId=nexus
效果如下

也可以同步本地仓库到私服上去



6.项目中的使用，这样就能在项目中引用了，具体的引用可以在pom中配置，也可以在maven的settings.xml文件中修改

<mirrors>

    <mirror>

      <id>nexus</id>

      <mirrorOf>*</mirrorOf>

      <url>http://127.0.0.1:8082/nexus/content/groups/public/</url>

    </mirror>

  </mirrors>

<profiles>

   <profile>

      <id>nexus</id>

      <repositories>

        <repository>

          <id>nexus</id>

          <url>http://127.0.0.1:8082/nexus/content/groups/public/</url>

          <releases><enabled>true</enabled></releases>

          <snapshots><enabled>true</enabled></snapshots>

        </repository>  

      </repositories>

     <pluginRepositories>

        <pluginRepository>

          <id>nexus</id>

          <url>http://127.0.0.1:8082/nexus/content/groups/public/</url>

          <releases><enabled>true</enabled></releases>

          <snapshots><enabled>true</enabled></snapshots>

        </pluginRepository>

      </pluginRepositories>

    </profile>

  </profiles>

  <activeProfiles>

    <activeProfile>nexus</activeProfile>

  </activeProfiles>

 7.上传项目到私服上去
先设置settings.xml,配置servers，见步骤5
项目的pom文件添加如下代码

<distributionManagement>

 <repository>

   <id>release</id>

   <name>Release Repository</name>

   <url>http://ip/nexus/content/repositories/releases</url>

 </repository>

 <snapshotRepository>

   <id>snapshot</id>

   <name>Snapshot Repository</name>

   <url>http://ip/nexus/content/repositories/snapshots</url>

 </snapshotRepository>

</distributionManagement>



执行deploy -e即可
