It looks like your Java installation is completely broken.
From a quick search, it looks like this is caused by a product from Micro Focus: https://stackoverflow.com/questions/10324186/error-message-in-trying-to-run-java
I recommend you install a proper standard JDK that is not tampered by a third party vendor (then check your PATH to make sure you have the correct one).

Thanks that helped resolve the issue.

But i still keep getting this warning

Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.
Use ‘–warning-mode all’ to show the individual deprecation warnings.
See https://docs.gradle.org/6.6.1/userguide/command_line_interface.html#sec:command_line_warnings

I have to use gradlew Clean the run the command : gradlew gatlingRun-computerdatabase.BasicSimulation for it to work.

Thanks,

warnings are warnings, not errors

But it does not run the simulation. it just returns warning. I need to do a gradle clean for simulation to run.
