## maven的settings.xml配置 ##

<server>
    	<id>releases-id</id>  
    	<username>admin</username>  
    	<password>admin123</password>  
    </server>  
    
    <server>  
    	<id>snapshot-id</id>  
    	<username>admin</username>  
    	<password>admin123</password>  
    </server>

*  `id`
    
    自定义`id`，表示一个`server`配置块，要保证唯一性，与`distributionManagement`中的`repository`元素的`id`匹配
 *  `username/password`
    
    服务器认证需要的登录名和密码，可由私服的`Role`和`User`等控制权限
 *  `privateKey/passphrase`（可选）
    
    两个元素指定了一个私钥的路径（默认是`/home/hudson/.ssh/id_dsa`）和一个密语。
 *  `filePermissions/directoryPermissions`（可选）
    
    权限对应了`linux`文件系统的权限，了解即可，如777.

## 项目pom文件配置 ##

<scm>
        <connection>
            scm:svn:http://xxx/svn/code/xxx/${ project.artifactId}/trunk
        </connection>
        <developerConnection>
           scm:svn:http://xxx/svn/code/xxx/${ project.artifactId}/trunk
        </developerConnection>
        <url>
        	http://xxx/svn/code/xxx/${ project.artifactId}/trunk
        </url>
    </scm>
    <distributionManagement>
    	<repository>
    		<id>releases-id</id>
    		<name>Release Repository</name>
    		<url>http://192.168.1.11:8081/nexus/content/repositories/releases</url>
    	</repository>
    	<snapshotRepository>
    		<id>snapshot-id</id>
    		<name>Snapshot Repository</name>
    		<url>http://192.168.1.11:8081/nexus/content/repositories/snapshots</url>
    	</snapshotRepository>
    </distributionManagement>

*  `distributionManagement`
    
    配置发布到私服的分发仓库
 *  `repository`
    
    配置最终版本`releases`的仓库，`deploy`时将项目的最终版本（`x.x.x`）发布到`releases`仓库
 *  `snapshotRepository`
    
    配置快照版本`snapshot`的仓库，`deploy`时将项目的快照版本（`x.x.x-SNAPSHOT`）发布到`snapshots`仓库

## 注意 ##

1.  `distributionManagement`中同时配置了`releases`和`snapshot`两个仓库，**但是每次只会有一个生效**！因为你`pom`文件中的`version`要么版本号带有`-SNAPSHOT`，要么只有版本号的`0.0.0`，因此`maven`在`deploy`的时候会根据`version`后缀来匹配发布到哪个仓库中。
2.  `distributionManagement`只配置了`releases`仓库，但是`pom`的`version`版本号带有`-SNAPSHOT`，此时你`deploy`的话，会报异常，如下异常
3.  在`nexus`私服，选中`Repositories`，选中`Releases`的仓库，在`Configuration`的`Access Settings`有`Deployment Policy`配置，默认是`Disable Redeploy`，表示一个版本只允许上传一次，不允许覆盖，否则会报异常如下异常
4.  异常
