Debugging mode not getting enabled

[ishank]

Gatling version: 3.14.3.7
Gatling flavor: java
Gatling build tool: gradle

I made sure I’ve update my Gatling version to the latest release
I read the guidelines and how to ask a question topics.
I provided a SSCCE (or at least, all information to help the community understand my topic)
I copied output I observe and explain what I think should be.

Hello Devs,

I have been trying to enable debugging mode in intellij idea and using the following configs:
using command
gatlingRun --same-process --simulation=

but everytime i runs it fails never start in debugging mode.
Is there any other way to make it work? I have followed all the steps mentioned in the docs.

I’ve just checked and it works for me.
Are you sure you’re launching “Debug” and not “Run”?
Also, make sure to update your IntelliJ IDEA version, there was a regression that was fixed some times ago.

As I said, it works on my side:

• clone GitHub - gatling/gatling-gradle-plugin-demo-java
• create configuration
  
  
• Edit the Simulation to add a function and a breakpoint in there

  private static final ScenarioBuilder scenario = scenario("Scenario").exec(
      http("Session").get("/session"),
      exec(session -> {
        System.out.println("Hello");
        return session;
      })
  );

• Debug
• Observe the debugger stop at the expected breakpoint
  
  

Please provide a way for us to reproduce your problem on our end.
