如何解决错误？

根据官方页面，您需要更改插件声明：

自版本2.0-beta-1以来，tomcat mojos已重命名为tomcat6和tomcat7，目标相同

您必须配置pom以使用此新的groupId:

org.apache.tomcat.maven

codehaus版本的一般建议

访问maven中央存储库

并搜索所需的类/Jar，获得最新/正确的
工件Id、组Id等

要下载JAR文件的正确版本
您是否在公司防火墙后面？？
<role rolename="manager"/>
<role rolename="admin"/>
<user username="admin" password="password" roles="admin,manager"/>

<servers>
    <server>
      <id>TomcatServer</id>
      <username>admin</username>
      <password>password</password>
    </server>
