How to run "gradlew runClient" in debug mode?

I am writing a mod for Minecraft.

I use neoforged/NeoGradle. I can run Minecraft client with my mod by

gradlew runClient

I know that the mod works, because I can see it in the game. I use IntellijIdea as IDE. And my break points in it don't work.

How to run "gradlew runClient" in debug mode?

You can run gradlew runClient in debug mode by following these steps:

Method 1: Using IntelliJ IDEA’s Built-in Gradle Debugging

  1. Open IntelliJ IDEA and load the mod project.
  2. Open the Gradle Tool Window
    • View → Tool Windows → Gradle (or press Alt + 9).
  3. Find runClient Task
    • Expand Tasks → forgegradle (or Tasks → neoforge depending on the setup).
    • Locate runClient.
  4. Run in Debug Mode
    • Right-click runClient and select Debug.

Method 2: Running from Terminal with Debug Flag

  1. Open a terminal inside IntelliJ (or any external terminal).

  2. Run the following command:

    gradlew runClient --debug-jvm

  3. IntelliJ will stop and wait for a debugger to attach.

  4. Go to Run → Attach Debugger to Process, and select the Minecraft process.

Now breakpoints should work properly.

If breakpoints still don't work, make sure:

  • The mod is compiled with debugging symbols (-g flag enabled in build.gradle).
  • The breakpoint is in code that is actually executed.
  • The mod is running in the same environment as the debugger.

Let me know if you need more help!
