java - mvn tomcat7:deploy执行成功但是项目并没有真正部署到tomcat

问题描述

运行mvn tomcat7:deploy后显示项目部署成功：

$ mvn tomcat7:deploy
...
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 8.893 s
[INFO] Finished at: 2017-04-14T17:44:30+08:00
[INFO] Final Memory: 13M/105M
[INFO] ------------------------------------------------------------------------

但是随后查看webapps下面可以发现项目并没有成功部署：

$ ls /usr/local/tomcat/webapps
docs  examples  host-manager  manager  ROOT

具体配置

pom.xml

    
        
            
                org.apache.tomcat.maven
                tomcat7-maven-plugin
                2.1
                
                    tomcat
                    http://localhost:8080/manager/html
                    /test
                    true
                
            
        
    

~/.m2/setting.xml

      
          tomcat
          admin
          123456
      

/usr/local/tomcat/conf/tomcat-users.xml

请问上面的步骤哪里出现了问题？为什么项目并没有成功部署到webapps下面？
