How to resolve the error "Unable to access jarfile ApacheJMeter.jar errorlevel=1" while initiating Jmeter?

Try downloading apache-jmeter-2.6.zip from http://www.apache.org/dist/jmeter/binaries/

This contains the proper ApacheJMeter.jar that is needed to initiate.

Go to bin folder in the command prompt and try java -jar ApacheJMeter.jar if the download is correct this should open the GUI.

  • The correct answer as of current modern JMeter versions is https://stackoverflow.com/a/51973791/460802

I got this error today because the "Source" is missing the ApacheJmeter.jar. I downloaded it again from "Binaries" and everything works as expected.
