I'm getting this error when trying to run this jmeter sentence from a maven project in java.

jmeter -g  DIRECTORY -o DIRECTORY

When I run it in cmd it works perfectly but when I try to run it using this:

processBuilder.command("cmd.exe","/c","jmeter -g  DIRECTORY -o DIRECTORY");
    processBuilder.directory(new File("C:\\apache-jmeter-5.3\\bin"));
    try {

      Process process = processBuilder.start();

It says The JMETER_HOME environment variable is not defined correctly

When I run the command echo %JMETER_HOME% it returns C:\apache-jmeter-5.3

What I found weird is that in other PC it all works fine and that one doesn't have the JMETER_HOME variable defined, so I tried deleting the variable from this PC but it won't delete, it's not appearing in the system variables window but when I echo it's there.

What is going on?

Thanks in advance

So you want us to guess what is the difference between one your PC and the other one without providing any information apart from incomplete code?

I can only state that I cannot reproduce your issue and yes, I don't have JMETER_HOME variable set anywhere.

If you're using Maven maybe it worth considering looking at JMeter Maven Plugin which can automatically download JMeter, run the test and generate the HTML reporting dashboard.

Also be informed that according to JMeter Best Practices you're supposed to use the latest version of JMeter so consider upgrading to JMeter 5.4.3 (or whatever is the latest version of JMeter available at JMeter Downloads page) on next available opportunity.

I faced same issue of JMETER_HOME not been set, even though I tried setting that Env variable. I was tying to launch the Jmeter on the Virtual system (VM) using command prompt, and didn't succeed. I able to solve it by running the command prompt as admin and launching Jemter, it worked fine.

Note: make sure you have the set the Env. PATH set to the bin folder of Jmeter
