Debugging through Maven (IntelliJ IDEA) does not work

Gatling (Open-Source)
2

Regarding `Unable to parse command line options: Unrecognized option: --add-opens=java.base/java.lang=ALL-UNNAMED`, I can only think of 2 possible sane explanations:

  1. your `temurin-21` is actually NOT Java 21 => verify the Java installation it points to
  2. you have some non printable character in your input => clean the “Run“ and “VM options“ input fields and fill them again manually, character by character

I can run my Gatling test, but the debugger does not stop at my breakpoints at all

Make sure you use up-to-date Gatling and gatling-maven-plugin versions.
