Exception in thread "main" java.lang.IllegalStateException: Failed to find system mod: minecraft

[Naamah]

I've tried different jdks, reinstalling minecraft, reinstalling IntelliJ, and restarting the project from scratch and I cant figure out why this error is happening.

Full error:

If the forge bootstrap can't find minecraft this will be an issue with your launcher.

If you are using the vanilla launcher post a link to the launcher_log.txt

otherwise speak to whoever produces your launcher.

I see that my minecraft launcher is installing it's installations to the curseforge client install location, but after running the runClient, it gives the error but neither the log for the vanilla launcher, nor the curseforge launcher change.

You need to explain better what you are doing.

runclient is a gradle task used in development, it will not use anything from a production environment like curseforge

 

If it can't find minecraft in the development environment, then you have likely broken your build.gradle in some way.

Or you have not run the relevant gradle task to setup the run configurations for your IDE if you are starting it that way.

This may sound like the weirded shit ever, but I refollowed the Getting Started section and it was all going well until I edited the mods.toml file. The only thing I changed in there was the name and author. If I don't touch the file, no error occurs and I can start the client like normal (gives an error, but the game actually starts).

So after a bunch of searching the error only happens when I change the modId="examplemod" to my own modid in the mods.toml file. I used a different modid and it worked, but it could just be that I am dumb as hell and cant solve a simple problem

I found out what's wrong. The modId has some reqirements, i had the same problem i changed it and it worked. You can find them here:https://forge.gemwire.uk/wiki/Mods.toml
