我想使用 maven-tomcat 插件在远程 Tomcat 上部署 WAR。但遇到问题并出现异常（如下所述）。请指导。

使用的命令：

mvn tomcat:redeploy

错误日志：

[ERROR] Failed to execute goal org.codehaus.mojo:tomcat-maven-plugin:1.1:deploy (default-cli) on project PageNameService: Cannot invoke Tomcat manager: Connection refused: connect - [Help 1]

您需要更新您的经理网址text从 tomcat6 到 tomcat7 的新变化

<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <url>http://secdevapp11.gspt.net:8888/manager/text</url>
        <server>UnixTomcatServer</server>
        <path>/{project.artifactId}</path>
    </configuration>
</plugin>

现在您可以运行 mvn tomcat7:deploy（或重新部署）
