CannotResolveClassException: org.apache.jmeter.protocol.http.sampler.HTTPSamplerProxy

When I am trying to run the JMX file from eclipse through java code, i am getting the error code and error as follows.

I have tried by adding plugin manager. 

<!-- https://mvnrepository.com/artifact/kg.apc/jmeter-plugins-manager -->
<dependency>
    <groupId>kg.apc</groupId>
    <artifactId>jmeter-plugins-manager</artifactId>
    <version>1.3</version>
</dependency>

package com.blazemeter.demo;

import org.apache.jmeter.engine.StandardJMeterEngine;
import org.apache.jmeter.save.SaveService;
import org.apache.jmeter.util.JMeterUtils;
import org.apache.jorphan.collections.HashTree;

import com.thoughtworks.xstream.XStream;

import java.io.File;
import java.io.FileInputStream;

public class RunTest {

    public static void main(String[] argv) throws Exception {
        // JMeter Engine
        StandardJMeterEngine jmeter = new StandardJMeterEngine();


        // Initialize Properties, logging, locale, etc.
        JMeterUtils.loadJMeterProperties("C:/Users/Public/softwares/apache-jmeter-5.0/bin/jmeter.properties");
        JMeterUtils.setJMeterHome("C:/Users/Public/softwares/apache-jmeter-5.0");
        JMeterUtils.initLogging();// you can comment this line out to see extra log messages of i.e. DEBUG level
        JMeterUtils.initLocale();

        // Initialize JMeter SaveService
        SaveService.loadProperties();

        // Load existing .jmx Test Plan
        File in = new File("C:\\Users\\Public\\SampleRun.jmx");
        HashTree testPlanTree = SaveService.loadTree(in);
        in.exists();

        // Run JMeter Test
        jmeter.configure(testPlanTree);
        jmeter.run();
    }
}

It appears that your pom.xml file is missing ApacheJMeter_http dependency

The minimal set of dependencies would be:

<dependencies>
    <dependency>
        <groupId>org.apache.jmeter</groupId>
        <artifactId>ApacheJMeter_java</artifactId>
        <version>5.1.1</version>
    </dependency>
    <dependency>
        <groupId>org.apache.jmeter</groupId>
        <artifactId>ApacheJMeter_http</artifactId>
        <version>5.1.1</version>
    </dependency>
</dependencies>

If your test relies on other test elements you need to locate the required library and explicitly declare it as the project dependency.
