Hi, I'm trying to use Citizens with Purpur 1.21 and I get this error when starting the server:

java.lang.NoClassDefFoundError: org/bukkit/craftbukkit/v1_21_R4/boss/CraftBossBar
...

I'm already using the latest snapshot (build 3800), but it still fails to load.
Is Citizens compatible with Minecraft 1.21 yet, am I missing something? Or is there a newer dev build I should try?

Thank you in advance for your help!

Info: logs

Please post your full latest log file.

Background Info: One of the most helpful tools to identifying the source of a problem is your server logs file! Logs contain all sorts of important information like server and plugin versions, any error messages, and a lot more important information (More Info).

How To: Your log can be found in the logs folder within your server folder. The most recent log is a text file labeled latest.log. To get help using these logs, please open that file in a text editor and copy all of the text, then open https://paste.denizenscript.com/New/Log and paste the text into the box on the page. Then click "Submit" and copy the URL and paste that back into this channel.

Please do not upload the file to Discord or to other pastebin services, use the log pastebin linked above.

Server Version

Purpur version 1.21-2273-ver/1.21@61b63b1 (2024-07-21T10:50:28Z)

Plugin Version(s)

Citizens v2.0.38-SNAPSHOT (build 3800) -- (Outdated build, behind by 6)

Checked For

@keen sierra

Online/Offline

Offline, but proxied.

Other Noteworthy Plugin(s)

WorldGuard v7.0.13+82fdc65, ProtocolLib v5.3.0

Possibly Relevant Plugin(s)

TAB v5.2.1 - This plugin adds Below_Name scoreboards to NPCs.
FastAsyncWorldEdit v2.12.3 - This plugin has been known to break the plugin load order on many servers, due to usage of the 'loadbefore' directive in its 'plugin.yml'.

Potentially Bad Line(s)

Starting Minecraft server on *:25565 - server is offline but has no address bind. This might mean you're using a system level firewall, but if not, it means your proxy is bypassable by hackers. Either enable a system level firewall, or bind your server to localhost in server.properties via server-ip=127.0.0.1.

1.21 isn't supported anymore, update to 1.21.5

#

!patchversion

# keen sierra !patchversion
Info: patchversion

We support only the latest patch-version of Minecraft for any recent main version (and Mojang, Spigot, Paper, etc. all generally also follow the same rule).

"Patch version" means the last number in a version label, for example in 1.20.6, the main version is 1.20, and the patch version is .6.
So if 1.20.6 is the latest patch version, then 1.20.3, and 1.20(.0) are all outdated patch versions, and therefore are unsupported.

Note that we do still support recent older main versions (such as 1.19 and 1.18) so long as you are on the latest patch-version of those main versions (like 1.19.4 and 1.18.2).
