Nexus私服搭建使用及发布jar包到私服上供团队其他成员使用

1.下载maven解压到指定目录，并配置环境变量 M2_HOME为maven解压目录

2.path中增加 %M2_HOME%in， 并确认 mvn -v 正确

3.下载nexus http://www.sonatype.org/nexus/archived/ 解压到指定目录

4.根据部署系统，执行D:soft exus-2.12.0-01-bundle exus-2.12.0-01injswwindows-x86-64console-nexus.bat  【我用的是win7 64位】

5.确认http://localhost:8081/nexus/ 能正常访问

6.用admin/admin123登录（为了安全，请及时修改密码）

7.打开 repositories 并选中 central 下 configuration选项卡，设置Download Remote Indexes 为true并保存

8.选中 central 并右键，点击 repair index （过段时间在browse index中查看）

9.根据需要就可以选中 3rd party下的artifact upload上传私有的jar包了，完毕可以看到对应的artifact xml

<dependency>
  <groupId>com.xiaochangwei</groupId>
  <artifactId>nexus-demo</artifactId>
  <version>0.01</version>
</dependency>

10.修改maven的setting.xml

  <mirrors>
    <mirror>  
      <id>nexus-public-snapshots</id>  
      <mirrorOf>public-snapshots</mirrorOf>  
      <url>http://localhost:8081/nexus/content/groups/public-snapshots</url>  
    </mirror>  
    <mirror>  
      <!--This sends everything else to /public -->  
      <id>nexus</id>  
      <mirrorOf>*</mirrorOf>  
      <url>http://localhost:8081/nexus/content/groups/public</url>  
    </mirror>
  </mirrors>

11.然后就可以在项目中使用搭建好的私服了。

下面讲发布公司项目jar包到私服供团队成员使用

1.在项目pom中增加发布地址

<distributionManagement>
        <repository>
            <id>user-release</id>
            <name>user release version</name>
            <url>http://localhost:8081/nexus/content/repositories/releases/</url>
        </repository>
        <snapshotRepository>
            <id>user-snapshots</id>
            <name>user snapshots version</name>
            <url>http://localhost:8081/nexus/content/repositories/snapshots/</url>
        </snapshotRepository>
    </distributionManagement>

2.修改maven的settings.xml

#定义profile并制定默认激活项

  <profiles>
    <profile>  
      <id>development</id>  
      <repositories>  
        <repository>  
          <id>central</id>  
          <url>http://central</url>  
          <releases><enabled>true</enabled></releases>  
          <snapshots><enabled>true</enabled></snapshots>  
        </repository>  
      </repositories>  
     <pluginRepositories>  
        <pluginRepository>  
          <id>central</id>  
          <url>http://central</url>  
          <releases><enabled>true</enabled></releases>  
          <snapshots><enabled>true</enabled></snapshots>  
        </pluginRepository>  
      </pluginRepositories>  
    </profile> 
  </profiles>

  <!-- activeProfiles
   | List of profiles that are active for all builds.
   |
  <activeProfiles>
    <activeProfile>alwaysActiveProfile</activeProfile>
    <activeProfile>anotherAlwaysActiveProfile</activeProfile>
  </activeProfiles>
  -->
  <activeProfiles>  
    <activeProfile>development</activeProfile>  
  </activeProfiles>

#定义用户认证

  <servers> 
   <server>
      <id>user-release</id>
      <username>deployment</username>
      <password>deployment123</password>
    </server>
    
    <server>
      <id>user-snapshots</id>
      <username>deployment</username>
      <password>deployment123</password>
    </server>
  </servers>

需要注意的是，这里的id和 第1步的id要完全一致

完整的settins文件如下

 | This is the configuration file for Maven. It can be specified at two levels:

 |
 |                 NOTE: This location can be overridden with the CLI option:
 |
 |                 -s /path/to/user/settings.xml
 |
 |  2. Global Level. This settings.xml file provides configuration for all Maven
 |                 users on a machine (assuming they're all using the same Maven
 |                 installation). It's normally provided in
 |                 ${maven.home}/conf/settings.xml.

 |
 |                 -gs /path/to/global/settings.xml

  <!-- mirrors
   | This is a list of mirrors to be used in downloading artifacts from remote repositories.

   | It works like this: a POM may declare a repository to use in resolving certain artifacts.
   | However, this repository may have problems with heavy traffic at times, so people have mirrored
   | it to several places.
   |
   | That repository definition will have a unique id, so we can create a mirror reference for that
   | repository, to be used as an alternate download site. The mirror site will be the preferred
   | server for that repository.
   |-->
  <mirrors>
    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
     |
     -->

      <!--This is used to direct the public snapshots repo in the   
          profile below over to a different nexus group -->

    </mirror>
     
  </mirrors>

  <!-- profiles
   | This is a list of profiles which can be activated in a variety of ways, and which can modify
   | the build process. Profiles provided in the settings.xml are intended to provide local machine-
   | specific paths and repository locations which allow the build to work in the local environment.
   |
   | For example, if you have an integration testing plugin - like cactus - that needs to know where
   | your Tomcat instance is installed, you can provide a variable here such that the variable is
   | dereferenced during the build process to configure the cactus plugin.
   |
   | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
   | section of this document (settings.xml) - will be discussed later. Another way essentially
   | relies on the detection of a system property, either matching a particular value for the property,
   | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a
   | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.
   | Finally, the list of active profiles can be specified directly from the command line.
   |
   | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
   |       repositories, plugin repositories, and free-form properties to be used as configuration
   |       variables for plugins in the POM.
   |
   |-->
  <profiles>
    <!-- profile
     | Specifies a set of introductions to the build process, to be activated using one or more of the
     | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
     | or the command line, profiles have to have an ID that is unique.
     |
     | An encouraged best practice for profile identification is to use a consistent naming convention
     | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
     | This will make it more intuitive to understand what the set of introduced profiles is attempting
     | to accomplish, particularly when you only have a list of profile id's for debug.
     |
     | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
    -->
    

    <!--
     | Here is another profile, activated by the system property 'target-env' with a value of 'dev',
     | which provides a specific path to the Tomcat instance. To use this, your plugin configuration
     | might hypothetically look like:
     |
     | ...
     | <plugin>
     |   <groupId>org.myco.myplugins</groupId>
     |   <artifactId>myplugin</artifactId>
     |
     |   <configuration>
     |     <tomcatLocation>${tomcatPath}</tomcatLocation>
     |   </configuration>
     | </plugin>
     | ...
     |
     | NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to
     |       anything, you could just leave off the <value/> inside the activation-property.
     |
    <profile>
      <id>env-dev</id>

      <activation>
        <property>
          <name>target-env</name>
          <value>dev</value>
