Try these ,
试试这些，
use redeployinstead of deploy
Default war size in tomcat is 50 MB, try to increase that if your war is bigger than 50 MB
Lots of users listed cause to me missing roles in tomcat-users.xml. Try adding manager-script role if missing , Question Link
Tomcat7 plugin might be picking server details from the maven conf settings.xml instead of .m2\settings.xml .Adding server information in that file might resolve issue.
使用重新部署而不是部署
tomcat 中的默认War大小为 50 MB，如果您的War大于 50 MB，请尝试增加该大小
列出的许多用户导致我缺少 tomcat-users.xml 中的角色。如果缺少，请尝试添加 manager-script 角色，问题链接
Tomcat7 插件可能会从 maven conf settings.xml 而不是 .m2\settings.xml 中选择服务器详细信息。在该文件中添加服务器信息可能会解决问题。
回答by Amine Aouffen
In addition to @Sabir Khan's answer. You need to check if the value of server in the plugin configuration is the same as the server id in the settings.xml
除了@Sabir Khan 的回答。需要检查插件配置中server的值是否与settings.xml中的server id一致
So in the pom.xmlyou are having :
所以在pom.xml你有：
<plugin>
...
<configuration>
...
<server>MyTomcatServer</server>
...
</configuration>
...
</plugin>
be sure in the settings.xmlof maven you have :
确保在settings.xmlMaven 中你有：
<servers>
...
<server>
<id>MyTomcatServer</id>
<username>username_here</username>
<password>password_here</password>
</server>
...
</servers>
Otherwise, tomcat will try to use admin account (if it is not configured, the server will refuse the auth)
否则tomcat会尝试使用admin账号（如果没有配置，服务器会拒绝auth）
