Spring MVC web.xml errors [closed]

Question

Full image of errors

So am doing course on spring and got to spring MVC, I imported spring lib and 2 more jar files that were also needed, and imported default web.xml from course. And I get 6 errors which makes no sense to me. I have no idea what any of this error means

1. "Multiple annotations found at this line:

   • There are '2' errors in 'http://www.oracle.com/webfolder/technetwork/jsc/xml/ns/javaee/ javaee_7.xsd'.
   • There are '43' errors in 'http://xmlns.jcp.org/xml/ns/javaee/web-common_3_1.xsd'.
   • There are '16' errors in 'http://www.oracle.com/webfolder/technetwork/jsc/xml/ns/javaee/ jsp_2_3.xsd'."

2. "There are '3' errors in 'http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd'."

3. "Invalid element name:

• display-name

One of the following is expected:

• module-name
• distributable
• context-param
• filter

• servlet-mapping
• session-config
• mime-mapping
• welcome-file-list
• error-page

4. "cvc-id.3: A field of identity constraint 'web-common-servlet-name-uniqueness' matched element 'web-app', but this element does not have a simple type."
