Actions to reproduce

Use adventure-platform-bungee in one plugin (shaded ofc), do something with adventure components in another plugin depending on the first one.

Tested with a basic default setup, a Lobby server (Purpur 1.19.3 for CN4, Paper 1.19.2 for CN3), and static waterfall-latest.

CN3

CN4

The mini plugin I reproduced this with can be found here:
https://github.com/itsTyrion/crashtest - I uploaded the compiled release incl the plugin with all the kotlin libs in releases.
For builds gradle buildArtifacts builds and collects the artifacts in a dist folder but gradle jar in both modules works too.

Kotlin isn't shaded with the current config tho - and it works in all plugins.
made a 2nd branch that shades kotlin and uploaded that as as release, too

I also have this problem

Solvable by using an older version of MiniMessage (4.12.0) and adventure-platform-bungeecord (4.2.0)

e: nevermind it's not :(

an temporary fix for this is maybe just using velocity instead :) but I will take a look at this

well actually this looks like a classloader bug which has nothing in common with cloudnet

[itsTyrion]

Solution: downgrade adventure-platform-bungeecord to a version that matches cloudnet and shade it but exclude adventure-api. Yes, even if the version matches CloudNet's version.

[derklaro]

This is very likely a BungeeCord issue. This error does not occur on other platforms. But if exclusion works go with it I guess. The shaded version of adventure was bumped to latest in the nightly builds :)
