Circular Plugin Loading Dependency with Multiverse-Core__

[imSpartann]

Hi MrMarL,

I noticed the following warning during server startup and wanted to report it.

[06:19:41] [Server thread/ERROR]: [LoadOrderTree] =================================
[06:19:41] [Server thread/ERROR]: [LoadOrderTree] Circular plugin loading detected:

I also noticed the following entries in OneBlock's plugin.yml:

loadbefore: ['Multiverse-Core']
softdepend: ['PlaceholderAPI', 'WorldGuard', 'ItemsAdder', 'Oraxen', 'Nexo', 'CraftEngine']

Environment:

• Paper 1.21.11 build 132
• OneBlock 1.6.2
• Nexo 1.19.1
• MythicMobs 5.12.0-SNAPSHOT
• Multiverse-Core 5.7.0-pre.1

The server continues to start and OneBlock appears to load successfully, but Paper consistently reports the circular plugin loading warning above.

Could you please investigate this and, if appropriate, resolve the circular dependency in a future update?

Thanks.

I removed the loadbefore entry from OneBlock and compiled it locally. After testing, the circular dependency warning with Multiverse-Core is gone on my server.

I also created a new OneBlock world using VoidGen as the generator and the world loads and functions normally.

Thanks for testing that, but removing loadbefore: [Multiverse-Core] actually breaks VoidGen on server reloads on my end — the world generator falls back to the default one. That dependency exists for a reason, so simply deleting it isn't a viable fix.

You can safely remove that line if you're not using the void world generator from my plugin. No need to recompile — just open the jar as an archive, delete the loadbefore line from plugin.yml, and you're good to go.
