Problem Description
Issue
I’m trying to setup a ATM10 To the Sky Minecraft server, but the Minecraft instance fails to start immediately with the following error:
Error: Could not find or load main class @libraries.net.neoforged.neoforge.21.1.215.win_args.txt
Looking at the support tab, the Las Args states the following:
-Xmx8196M -Xms256M @libraries/net/neoforged/neoforge/21.1.215/win_args.txt
Reproduction Steps
- Created a new Minecraft Jave instance
- In Configuration → Minecraft → Server Settings: Change Server Type to NeoForge and version to 21.1.215. Left Server JAR at [Autoselect]
- Clicked Download/Update under Server type to allow instance to install NeoForge.
- Waited for Installation process to complete
- Returned to Status page and clicked Start
- Accepted EULA
