I can't open my server (1.12.2)

Posted March 7, 20232 yr

I've recently been trying to make a localhost minecraft server to test things. When I start it I get several errors:

java -Xmx4G -Xms1024M -jar forge-1.12.2-14.23.5.2860.jar nogui

A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException

Can someone help me to solve it?

Failed loading villager cartographer registered at cartographer - frozen tick

Allocated 10 Gb of ram. Could try again with more but I read using too much can slow things down as well. Going to try another big modpack and see if i can replicate the problem. It seems like this cartographer problem is kind of popular and doesn't have a solid solution yet, but i suspect its some generation mod since it's a crash that happens when specific chunks are being loaded. so i'll still try to lookout for what mod it could be as i add. i'll report back after testing as you suggested for a bit

I have no idea - is enough RAM allocated?
Do other pre-configured modpacks work? Maybe use such a modpack as working base and add new mods one by one

Minecraft Mod Gradle Build not working

The settings.gradle file has been fixed. But, the build.gradle has an error now.
Error:
* Where:
Build file 'C:\Users\csonn\OneDrive\Desktop\fusionlucky\build.gradle' line: 3
* What went wrong:
Plugin [id: 'net.minecraftforge.gradle', version: '6.1.+'] was not found in any of the following sources:
- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Included Builds (No included builds contain this plugin)
- Plugin Repositories (could not resolve plugin artifact 'net.minecraftforge.gradle:net.minecraftforge.gradle.gradle.plugin:6.1.+')
Searched in the following repositories:
Gradle Central Plugin Repository
MinecraftForge
Forge Maven
Forge Maven
Maven Repository for Minecraft Forge. <br/>You should be on:)
* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
