Preliminaries:

Shopkeepers version: 2.22.1
Spigot version: 4267-Spigot-5bbef5a-403accd (MC: 1.21) (Implementing API version 1.21-R0.1-SNAPSHOT)

I have checked that my issue/question does not get answered by:
- The documentation.
- The FAQ.
- The Known Issues.
I have checked all open and closed issues, but none seems to fit my issue/question.

Reproduction on a fresh and up-to-date Spigot server:

I was able to reproduce my issue on a freshly set up and up-to-date Spigot server (currently 4267-Spigot-5bbef5a-403accd (MC: 1.21) (Implementing API version 1.21-R0.1-SNAPSHOT)) with the latest version of Shopkeepers (currently 2.22.1), with no other plugins and with no kinds of other server or client mods.

The issue:

Description of the issue.

When starting the server, as mentioned in the title, an error message along with several stack traces and races is output, and the plugin is not enabled.

Step-by-step instructions on how to reproduce the issue.

Create a new folder.
Place spigot-1.21.jar and eula.txt in the folder.
Create a plugins folder and place Shopkeepers-2.22.1.jar in it.
Run java -jar spigot-1.21.jar -nogui.

Observed behavior.

Refer to the server logs. The /plugins command outputs Plugins (0):.

Expected behavior.

The plugin should be enabled.

Server logs (from server startup until issue). Consider enabling debug mode in the config for additional console output.

Yes, the plugin is currently broken on the latest server versions of 1.21. There is currently no fix yet. I will post an update once this issue is fixed. No ETA.

Any news on this?

planethouki · Answer 4 · 2024-07-25T07:54:04.000Z

The author says in version 2.22.2 that ‘This version only works on Spigot versions from before 2024-07-06.

blablubbabc · Answer 5 · 2024-07-26T22:23:19.000Z

Will be fixed with the next update (v2.22.3), probably available within the next few days.
