maven-配置私服提交权限

自定义的jar包提交到nexus的私服中，直接通过maven命令提交。

```shell

mvn clean source:jar deploy -X -DskipTests=true

```

参数解释：

*clean 清空上次编译结果

*deploy 发布到情况

*source:jar 同步发布源码

*-X debug级别日志输出

*-DskipTests=true 跳过单元测试

执行的过程中出现一个错误：

``` shell

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project io: Failed to deploy artifacts: Could not transfer artifact cn.infisa:io:jar:1.0.2-RELEASE from/to releases (http://192.168.1.62:8081/nexus/content/repositories/releases/): Failed to transfer file: http://192.168.1.62:8081/nexus/content/repositories/releases/cn/infisa/io/1.0.2-RELEASE/io-1.0.2-RELEASE.jar. Return code is: 401, ReasonPhrase: Unauthorized. -> [Help 1]

```

原因：　本地用户提交releases或者snapshots里面，需要配置对应的权限，而且需要在settings.xml中配置。

```xml

username

password

releases

```

再次提交，成功通过。
