The superclass javax servlet http HttpServlet was not found on the Java Build Path

Question

I have a project that Eclipse's Maven integration produced. All function properly, but all JSP files have the following in the workspace:

The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path

To the first string where place:

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>

When I add JSP to a simple dynamic web project, everything runs smoothly and without any issues.

Include servlet-api-3.1.jar in your dependencies.

• Maven

  <dependency>
      <groupId>javax.servlet</groupId>
      <artifactId>javax.servlet-api</artifactId>
      <version>3.1.0</version>
      <scope>provided</scope>
  </dependency>
  

• Gradle

  configurations {
      provided
  }
  sourceSets {
      main { compileClasspath += configurations.provided }
  }
  dependencies {
      provided 'javax.servlet:javax.servlet-api:3.1.0'
  }
