[SOLVED] [1.15.2] Unable to launch example mod in eclipse


Recommended Posts

Posted (edited)

Hello,

 

I am learning how to create mods using the MDK. I was able to configure the mod folder and import the project into Eclipse. If I run the program even without editing anything it crashes with the following message :

[Render thread/ERROR] [ne.mi.ev.EventBus/EVENTBUS]: Failed to resolve handler for "net.minecraftforge.fml.network.simple.SimpleChannel$$Lambda$2232/0x000000080139e840@471d6571"

 

I am coding on Ubuntu. I have multiple jdk, with openjdk-8 as the default on.

The crash report  :

// But it works on my machine.

It's using Java 13 instead of the Java 8 installation you want it to. I don't use Eclipse, but this should tell you what to do to change it to Java 8.

I'm eager to learn and am prone to mistakes. Don't hesitate to tell me how I can improve.

    • So me and a couple of friends are playing with a shitpost mod pack and one of the mods in the pack is corail tombstone and for some reason there is a problem with it, where on death to fire the player will get kicked out of the server and the tombstone will not spawn basically deleting an entire inventory, it doesn't matter what type of fire it is, whether it's from vanilla fire/lava, or from modded fire like ice&fire/lycanites and it's common enough to where everyone on the server has experienced at least once or twice and it doesn't give any crash log. a solution to this would be much appreciated thank you!
    • It is 1.12.2 - I have no idea if there is a 1.12 pack
    • Okay, but does the modpack works with 1.12 or just with 1.12.2, because I need the Forge client specifically for Minecraft 1.12, not 1.12.2
    • Version 1.19 - Forge 41.0.63 I want to create a wolf entity that I can ride, so far it seems to be working, but the problem is that when I get on the wolf, I can’t control it. I then discovered that the issue is that the server doesn’t detect that I’m riding the wolf, so I’m struggling with synchronization. However, it seems to not be working properly. As I understand it, the server receives the packet but doesn’t register it correctly. I’m a bit new to Java, and I’ll try to provide all the relevant code and prints *The comments and prints are translated by chatgpt since they were originally in Spanish* Thank you very much in advance No player is mounted, or the passenger is not a player.
