NoClassDefFoundError when detecting Brigadier support on Java 17 using Paper 1.8.8 forks

MindsMaster opened this issue ยท 0 comments

Description

When running LuckPerms v5.5.9 on a Paper 1.8.8 fork (e.g., ImanitySpigot) with Java 17+, the plugin fails to load due to a NoClassDefFoundError when calling Class.forName(...) to detect Brigadier support.

This issue does not occur under Java 8.

Reproduction Steps

  1. Use ImanitySpigot or another Paper 1.8.8-based fork
  2. Run server with Java 17+
  3. Install LuckPerms latest
  4. Start the server

Expected Behaviour

The plugin should detect that Brigadier is not present and continue loading normally, just like under Java 8.
