jstl not working with error(The absolute uri: [http://java.sun.com/jsp/jstl/core] cannot be resolved)

Question

To try to use jstl, i installed jstl 1.2 library with maven. But still when i run the jsp pages through this message " The absolute uri: [http://java.sun.com/jsp/jstl/core] cannot be resolved in either web.xml or the jar files deployed with this application"

I've read this stackoverflow page, done what i am told, but it does not solve my issue.

I am using jdk 1.8 and tomcat 8.5 I will attatch full error report and part of my codes.

Apache Tomcat/8.5.16

and this is my pom.xml file

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>ch06</groupId>
    <artifactId>ch06</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <build>
        <sourceDirectory>src</sourceDirectory>
        <plugins>
            <plugin>

        </plugins>
    </build>
    <dependencies>
        <dependency>

            <version>1.2</version>
        </dependency>
  </dependencies>
</project>

and this is part of my web.xml file with concision.

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                             http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
</web-app>

and this is my jsp code, that include jstl core lib.

<%@page contentType="text/html" pageEncoding="utf-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<c:import url="/includes/header.html" />
