now that GatlingPropertiesBuilder has been removed how do you run a gatling simulation from within IntelliJ?
I would like to use IntelliJ’s debugging tools (eg. breakpoints) when running a simulation, but how is that possible now that the above class and runner have been removed?

Gatling has an asynchronous engine and virtual users are running concurrently. So it’s really not breakpoint/debugger friendly.

shame, with the old GatlingRunner I was able to use IntelliJ breakpoints and debug my code when running 1tps for 1 second … was a really useful method for debugging. Seems like taking a backward step not having this ability anymore
