Found the problem, was using the tomcat7-maven-plugin with compile version of maven-compiler-plugin 1.8, after changing it to 1.7 the problem gone. However is there any similar solutions to tomcat7-maven-plugin?, cause I didnt find tomcat8-maven-plugin in internet

Thanks everyone for participation

I just recently had this issue. I solved it by updating the java.version in the pom and then recompiling. Then the error went away. – dev4life Jan 14 '22 at 19:40

Open settings below:
Project settings -> Facets -> Web -> Deployment Descriptors

check the path here and ensure it's available. If not, click the green + to add your web module path.

You need to add servlet mapping also and then add spring-webmvc-version.jar in classpath

<servlet>
    <servlet-name>appServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>appServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

I was having this same problem. It turned out that I was using an old companies settings.xml file for Maven user settings file. If someone is having this problem try using the Maven template users file.

Add spring mvc.jar file (if you are using spring and mvc) to the class libraries
Make sure that [name]-sevlet.xml file is set properly. use name inside the "sevlet-name" name "servlet-name" in the web.xml.

I add the path for Web module. Using Intellij click project structure and then select Facets. Deployment Descriptors probably must be empty(its not good), so add the path.
