我已经在Intellij Idea中创建了Maven项目，并且尝试部署应用程序时出现错误。请帮我解决这个问题。

 [INFO] ------------------------------------------------------------------------

请您参考如下方法:

确保已在 distributionManegement 中定义了存储库元素:

<distributionManagement> 
    <repository> 
        <id>central</id> 
        <name>plugins-releases</name> 
        <url>http://serverip:8081/artifactory/plugins-release-local</url> 
    </repository> 
    <snapshotRepository> 
        <id>snapshots</id> 
        <name>plugins-snapshot</name> 
        <url>http://serverip:8081/artifactory/plugins-snapshot-local</url> 
    </snapshotRepository> 
</distributionManagement>
