Paper does not yet remap their internal Minecraft code from complete Mojmap to match Spigot's 1.17 handling (NMS), so this error is known and has to be fixed on Paper's end. Thank you anyway!

Camotoy commented 3 years ago

This should now be fixed on the latest commit of Paper 1.17. My explanation of why it was not working was incorrect - Paper did already remap to Spigot's form of NMS, but there was a bug in it handling a certain type of class.

I am getting the same error message for my 1.20.2 spigot server:

Error occurred while enabling floodgate v2.2.2-SNAPSHOT (b69-492be77) (Is it up to date?)

ha-rriz commented 11 months ago

Yeah same here

Tim203 commented 11 months ago

The issue you're describing is #448 which has been fixed in the latest build

I guess this just means waiting for a new floodgate snapshot?

Tim203 commented 4 months ago

Note that ExceptionInInitializerError is a generic Floodgate error when something specific cannot be found (usually means that either Floodgate is outdated or doesn't yet support that specific server version), so future readers please check if there is an issue for your specific server version (and otherwise create an issue) and comment on there.
