maven web.xml The element type “web-app” must be terminated by the matching end-tag “</web- app>”

Question

Eclipse Java EE IDE
Apache Tomcat v9.0
I created the project by New->Maven Project, and select the Maven archetype as maven-archetype-webapp.
web.xml content is as below.

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    id="WebApp_ID" version="3.0">
    <display-name>WebProject</display-name>
    <servlet>
        <servlet-name>LoginServlet</servlet-name>
        <display-name>LoginServlet</display-name>
        <servlet-class>com.wise.LoginServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>LoginServlet</servlet-name>
        <url-pattern>/LoginServlet</url-pattern>
    </servlet-mapping>
</web-app>

project structure in eclipse as below

there are two errors:
The element type "web-app" must be terminated by the matching end-tag "".
cvc-complex-type.2.4.a: Invalid content was found starting with element 'display-name'. One of '{"http:// java.sun.com/xml/ns/javaee":servlet-class, "http://java.sun.com/xml/ns/javaee":jsp-file, "http://java.sun.com/ xml/ns/javaee":init-param, "http://java.sun.com/xml/ns/javaee":load-on-startup, "http://java.sun.com/xml/ns/ javaee":enabled, "http://java.sun.com/xml/ns/javaee":async-supported, "http://java.sun.com/xml/ns/ javaee":run-as, "http://java.sun.com/xml/ns/javaee":security-role-ref, "http://java.sun.com/xml/ns/ javaee":multipart-config}' is expected.

Anyone can give some ideas?

Remove this header and try

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

and add the header schema reference

<?xml version="1.0" encoding="UTF-8"?>

maven web.xml The element type “web-app” must be terminated by the matching end-tag “</web- app>”
