Empty csv file showing non empty in report generation in non-gui mode in jmeter

Question

I am trying to generate an HTML report dashboard for JMeter test in NON-GUI mode with a command

jmeter -n -t C:\apache-jmeter-5.1.1\apache-jmeter-5.1.1\bin\DeviceManagementSystem1.jmx -l C:\Users\user\Desktop\Test\Reports\Report.csv -e -o C:\Users\user\Desktop\Test\Reports\Htmlreport\Report 

it is showing error

Error in NonGUIDriver java.lang.IllegalArgumentException: Results file:C:\Users\user\Desktop\Test\Reports\Report.csv is not empty

But I have made an empty CSV file by saving an empty .xlxs file as CSV file

Answer 1

Add -f command line argument (available since JMeter 2.13) to your JMeter startup line like:

jmeter -n -t C:\apache-jmeter-5.1.1\apache-jmeter-5.1.1\bin\DeviceManagementSystem1.jmx -l C:\Users\user\Desktop\Test\Reports\Report.csv -f -e -o C:\Users\user\Desktop\Test\Reports\Htmlreport\Report

This parameter will "tell" JMeter to overwrite the existing results file and the HTML reporting dashboard folder with the new results.
