maven自动打包上传nexus仓库配置

　　一个基础类，可能要升级并放到私服库里，为了方便，应该能够自动打包放到nexus。这就需要配置maven一些参数与pom.xml。

依次在settings.xml文件裡輸入

 <!-- nexus帳號和密碼-->

   <server>
     <id>releases</id>
     <username>admin</username>
     <password>admin123</password>
   </server>
   <server>
     <id>snapshots</id>
     <username>admin</username>
     <password>admin123</password>
   </server>
 </servers>

...

<!-- 引用naxus倉庫組-->
   <profile>
       <id>dev</id>
          <repositories>
             <repository>
                 <id>nexus</id>
                 <url>http://127.0.0.1:8081/nexus/content/groups/public/</url>
                 <releases>
                    <enabled>true</enabled>
                 </releases>
                 <snapshots>
                    <enabled>true</enabled>
                 </snapshots>
              </repository>
            </repositories>
            <pluginRepositories>
                <pluginRepository>
                    <id>nexus</id>
                    <url>http://127.0.0.1:8081/nexus/content/groups/public</url>
                    <releases>
                        <enabled>true</enabled>
                    </releases>
                    <snapshots>
                        <enabled>true</enabled>
                    </snapshots>
                </pluginRepository>
            </pluginRepositories>
        </profile>
..

 <!-- nexus -->
  <activeProfiles>
        <activeProfile>dev</activeProfile>

    </activeProfiles>

注意：根據標籤位置準確輸入

在本项目的pom.xml配置即可 
<!--上传配置 必须--> 

<distributionManagement>
<repository>
<id>releases</id>
<url>http://127.0.0.1:8081/nexus/content/repositories/releases</url>
</repository>
<snapshotRepository>
<id>snapshots</id>
<url>http://127.0.0.1:8081/nexus/content/repositories/snapshots</url>
</snapshotRepository>
</distributionManagement>

<!--上传source.jar 非必须-->

<build>

<plugins>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-source-plugin</artifactId>

<executions>

<execution>

<id>attach-sources</id>

<goals>

<goal>jar</goal>

</goals>

</execution>

</executions>

</plugin>

</plugins>

</build>

上面的ID和pom.xml中对应distributionManagement-> repository的ID，用户名和密码需要在nexus中配置。

完成以上配置，只要输入命令：mvn deploy 即可。

遇到的问题：

maven deploy到nexus报错：Return code is: 401, ReasonPhrase:Unauthorized

提交到nexus时候报错：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project *: Failed to deploy artifacts: Could not transfer artifact *:jar:1.0 from/to releases (http://10.1.81.199:8081/nexus/content/repositories/releases/): Failed to transfer file: http://10.1.81.199:8081/nexus/content/repositories/releases/com/cs2c/security-management-client* /1.0/*-1.0.jar. Return code is: 401, ReasonPhrase:Unauthorized.

原来是没有配置认证。

maven目录conf的setting.xml里，

  <server>
    <id>releases</id>
    <username>admin</username>
    <password>admin123</password>
  </server>
 <server>
  <id>snapshots</id>
  <username>admin</username>
  <password>admin123</password>
  </server>
</servers>

用户名和密码都是nexus的。再次deploy即可。

注意这里的id要和pom.xml里远程deploy的地址对应一致，我的pom.xml里配置：

<!-- 配置远程发布到私服，mvn deploy -->
    <distributionManagement>
        <repository>
            <id>releases</id>
            <name>Nexus Release Repository</name>
            <url>http://10.1.81.199:8081/nexus/content/repositories/releases/</url>
        </repository>
        <snapshotRepository>
            <id>snapshots</id>
            <name>Nexus Snapshot Repository</name>
            <url>http://10.1.81.199:8081/nexus/content/repositories/snapshots/</url>
        </snapshotRepository>
    </distributionManagement>
