I am running a .jmx file using JMeter java code in my maven project. I have recorded a .jmx file using blazemeter. Please refer to the below code that I have tried. 

package com.solitera.automation.controller; 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 java.io.File; import java.io.FileInputStream; public class JMeterFromExistingJMX { public static void main(String[] argv) throws Exception { // JMeter Engine StandardJMeterEngine jmeter = new StandardJMeterEngine(); // Initialize Properties, logging, locale, etc. JMeterUtils.loadJMeterProperties("D:/apache-jmeter-5.1.1/bin/jmeter.properties"); JMeterUtils.setJMeterHome("D:/apache-jmeter-5.1.1"); 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 /* FileInputStream in = new FileInputStream("D:/Ecllipse_project_workspace2/slt_automation/src/test/jmeter/slt_autoMa_Test.jmx"); HashTree testPlanTree = SaveService.loadTree(in); in.close();*/ HashTree testPlanTree = SaveService.loadTree(new File("D:/apache-jmeter-5.1.1/extras/slt_autoMa_Test.jmx")); // Run JMeter Test jmeter.configure(testPlanTree); jmeter.run(); } }

After run as a Java Application in eclipse -> Output is :

From the error you're getting it seems that your test is using HTTP Header Manager and you don't have the ApacheJMeter_http package which provides this class.

The interim solution would be adding the next Maven dependency to your pom.xml:

<!-- https://mvnrepository.com/artifact/org.apache.jmeter/ApacheJMeter_http --> <dependency> <groupId>org.apache.jmeter</groupId> <artifactId>ApacheJMeter_http</artifactId> <version>5.2.1</version> </dependency>

I would also recommend removing these httpcore and xstream dependencies from your pom.xml as Maven will get them as transitive dependencies of JMeter Core and HTTP packages.

Depending on your test nature you might need other packages, JMeter Plugins, so it's quite hard to say what else you may need.

Thanks for your answer, It has removed some errors and given me some response from JMeter but I am so perplexed right now after seeing the logs given by Jmeter. I am going to post that errors as a seprate answer within this page and you can check the same from that result, Please assist me and have a look on these errors, Thank You !!
