GATLING_HOME is set to /c/Users/Admin/Desktop/Performance/Gatling_Report/gatling-charts-highcharts-bundle-3.0.3
Error: Could not find or load main class io.gatling.app.Gatling

I have tried with gatling-charts-highcharts-bundle-2.3.1 version too still got the same error

It looks like you’re using a bash emulator on Windows. Try using the bat script on standard Windows CLI instead.

I tried with bat script getting the below issue.

$ bash /c/Users/Admin/Desktop/Performance/Gatling_Report/gatling-charts-highcharts-bundle-3.0.3/bin/gatling.bat -ro /Users/Admin/Desktop/Performance/Results/Promise-En

You’re not directly running on Windows.
/c/Users/Admin is definitively not a Windows path.

Run standard Windows cli, not a linux shell emulator.

Tried in Windows cli, But got this below error.

No idea what you’re doing. It looks like your simulation.log file is corrupted/has not the expected format.

Hi Rajesh,

I think your IntelliJ setup is not proper. Why don’t you try with VS Code and see if it works?

Hope this helps.
