I've tried to code a new forge mod with the example on minecraftforge.net
After importing with Gradle and generating run configurations, I tried to start the client with the example.
I used java liberica-1.8 and the latest forge mdk - 14.23.5.2860 for Minecraft 1.12.2.
Unfortunately, the client crashed immediately, with the following log output:
[22:18:59] [Client thread/DEBUG] [FML]: Examining file idea_rt.jar for potential mods
