How to make compatible with CommandPack plugin?

Hi there!

I’m developing my plugin (here’s the link: GitHub - TonisfelTr/LoreWriter at master). When I start the server separately from CommandPack (Semenkovsky_Ivan / CommandPack), both plugins work fine individually. But if I run the server with both plugins installed simultaneously, it crashes immediately with the following error:

[Server thread/FATAL]: Mixin apply failed commandpack.mixins.forge.json:game.MixinPortalShapeImpl → net.minecraft.world.level.portal.PortalShape: org.spongepowered.asm.mixin.transformer.throwables.InvalidMixinException @Shadow method createPortalBlocks in commandpack.mixins.forge.json:game.MixinPortalShapeImpl was not located in the target class net.minecraft.world.level.portal.PortalShape. No refMap loaded.

Full error excerpt:

Versions used:

  • Minecraft: 1.21.4
  • Forge: 54.1.0
  • SpongeForge: 1.21.4-54.0.12-14.0.0-RC2168

What could cause this conflict? Am I doing something incorrectly with my plugin or is there an incompatibility between the two plugins?

May want to report it to the commandpack github as im not seeing anything that should block command packs mixins from applying in your code

Wow AI response is really clear there. Stating there maybe a compatiblely issue between a sponge plugin and sponge itself.

Its always a good laugh
