In pom.xmlI have this:

Also in Maven/conf/settings.xmlI have:

But I typed in tomcat-users.xmlthat user admin has manager-gui role. I'm using Tomcat 7.0.56 and Jenkins. Also use commands: clean and tomcat7-redeploy. Need help to understand what is wrong:C
但是我在tomcat-users.xml中输入了用户 admin 具有 manager-gui 角色。我正在使用 Tomcat 7.0.56 和 Jenkins。还可以使用命令：clean 和 tomcat7-redeploy。需要帮助来理解什么是错的：C

In my case settings looked ok, but I already had the same webapp uploaded to tomcat and hadn't specified
在我的情况下，设置看起来不错，但我已经将相同的 webapp 上传到了 tomcat 并且没有指定
<update>true</update>
in tomcat plugin in pom.xml
在 pom.xml 中的 tomcat 插件中

Users with the manager-gui role should not be granted either the manager-script or manager-jmx roles.
不应授予具有 manager-gui 角色的用户 manager-script 或 manager-jmx 角色。
so,user admin should remove the role "manager-gui"
所以，用户管理员应该删除角色“manager-gui”

I added
我加了
<server>
<id>tomcat7</id>
<username>admin</username>
<password>admin</password>
</server>
in user/.m2/settings.xml
在用户/.m2/settings.xml
Also I didn't change pom.xml, tomcat-users.xml and Maven/conf/settings.xml and now all works fine.
此外，我没有更改 pom.xml、tomcat-users.xml 和 Maven/conf/settings.xml，现在一切正常。

Environment -> Windowd 8.1 + Maven 3 + Tomcat 8.1.15 + JDK 1.8 Also, I had to use tomcat:redeploy

ALso, update your maven settings via -> Preferences->Maven->User Settings to point to your maven settings.xml file. Add the values of the server in the maven settings.xml ( servers section and add the tomcat server details there). Use that here( for me the id is TomcatServer )
此外，通过 -> Preferences->Maven->User Settings 更新您的 maven 设置以指向您的 maven settings.xml 文件。在 maven settings.xml（服务器部分并在那里添加 tomcat 服务器详细信息）中添加服务器的值。在这里使用它（对我来说，id 是 TomcatServer ）
