Short description:

Upon adding Integrated REST to my modpack, Minecraft crashes as startup with the following exception:

Exception in thread "main" java.lang.module.ResolutionException: Modules integratedrest and io.netty.resolver export package io.netty.resolver to module mekanism

The modules range from Mekanism to Caelus API to Dismount Entity (those I've observed so far, seems random each time I load). Integrated REST appears to be the common cause.

Steps to reproduce the problem:

1. Add Caelus API, Dismount Entity or Mekanism mods along with Integrated REST (and it's requirements).
2. Observe exception on startup.

Expected behaviour:

Minecraft should load without crashing.

Versions:

• This mod: 1.1.6
• Minecraft: 1.19.2
• Forge: 43.1.3
• Mekanism: 10.3.3.470
• Dismount Entity: 1.8
• Caelus API: 3.0.0.6

At first glance, it looks like the jar shadowing is failing somehow.

Thanks for reporting!

Hi, I am playing in a modpack and after I installed this mod the same problem happens, the only difference is that I can load the world for a few minutes before it crashes, but the modules is random each time as well, so I figure is the same problem as this one since it has been fixed for version 1.19.
I was wondering, could you fix this issue for minecraft 1.12? Would that be easy to implement for this version?
I didn't want to open another issue because it would be duplicate of this one.
Thanks in advance.

I'm sorry, but MC 1.12 is not supported anymore.
