A new version has been released for Nucleus, it is available for download here.
Nucleus 1.2 Pre-release 4
This build is for Minecraft 1.12.2+ (Sponge API 7) ONLY
Nucleus 1.1.8 LTS is available for 1.10.2 and 1.11.2
This is a preview release. Not all the testing that you would come to expect has been performed on this build for a very specific reason - this is a build for Sponge bleeding, and changes are possible that will break this build. A full 1.2 release will be made when Sponge API 7 is declared stable.

Important Changes & Notices
Are you upgrading from Nucleus 0.x? Upgrade to 1.0.1 first.
Nucleus 1.1 removes a lot of old migration code that has been in the codebase since the very early days. 1.0.1 is the last version that contains this migration code, anyone updating directly from 0.x to 1.1 may not get a smooth migration.
[PR2] Backup your data! Codebase cleanup!
Nucleus 1.2 has undergone a lot of changes to remove a lot of redundant code. While this should make the plugin more stable, there may be minor issues that have arisen. Nothing should break, but please keep a backup of your data before installing 1.2 PR3.
[PR2] Removal of config key
If this config key was set to
false, you should now grant the players in question the
[PR4] Add gamerules alias & suggest command click actions
Thanks to Mohron, you can now run
/gamerules as an alias to
/world gamerule. Clicking on a gamerule will suggest a command to alter it.
[PR4] Add force flag for /spawn
Now, you can run
/spawn -f to force yourself to the set spawn, even if it’s not safe.
[PR4] Added invulnerability module
Previous, invulnerability was in the
misc module. It is now in its own separate module as the featureset got large enough for it to be in its own module.
Those who are invulnerable through Nucleus’ mechanisms should not be targeted by mobs any longer.
[PR4] Added way to track potential world UUID changes.
On each startup, Nucleus determines the mapping of world name -> UUID. If a world doesn’t match the UUID on subsequent startups, Nucleus whitelists the server and offers the
/repairuuid command, which will correct it and shutdown the server if it can find the right methods.
This does not fix world UUIDs changing, but it alerts you and offers to fix the problem if it ever is detected.
[PR4] Added vanish on login permission
Players with the permission
nucleus.vanish.onlogin will now log in and vanish immediately.
Now, a new way to dispose of your items! Brings up an inventory window, put your items in, close the inventory, and they are digital history!
[PR3] Added warning messages on startup in some scenarioes
Nucleus works best with a permission plugin and an economy plugin - it doesn’t provide these functions itself. If you don’t have these, Nucleus will warn you on startup.
Also, if Nucleus can’t take a command name, it will now warn you on startup too.
[PR3] More world commands
You can now copy and rename worlds using
/world clone and
[PR2] Changes due to the Sponge Cause Refactor
Nucleus now supports the Sponge CauseStackManager and will fail to run on older builds. This should not affect the general player, but there are developer centric things to keep in mind. These will be documented in the Developers section of these notes.
/enchanttable (with caveats)
You can now, thanks to advances in the Sponge API, call a virtual workbench and anvil. You can also call an enchantment table, but there is no way to set its power right now - it will be a very low power table! We hope to be able to add this to Sponge and bring this in a future update.
[PR2] Added blacklist for command spy
Now, you can specify either commands to be able to spy on, or commands NOT to spy on, bring this up to parity with the command logger.
[PR2] Updated World pre-gen code
We’ve made a few quality of life changes to the world gen system:
- Remove a lot of the spam caused by world generation by default, replacing with a more friendly notification, timed with the general player notification frequency
- Add option to re-add spam (if you’re really into that sort of thing)
- Decoupled save interval and player notification interval
-f flag to control the tick interval for pre-gen (how often the pre-gen code runs, number of ticks between generations - defaults to Sponge default)
There has also been some cleanup of the code.
New aliases for
/time set and
Not really much more to say than that, but now you won’t have to worry about getting that command wrong all the time!
As a related note, if a small change like this will help you with using the plugin, please tell us. This plugin is for the community!
New commands for kits:
/kit info and
Server admins can now view at a glance info about kits by running
/kit info [kit]. Servers can also give the
/kit view command to players, which will allow them to look at a kit without redeeming it.
Prevent players from accessing no-go worlds with world access permissions!
@Mohron has added per-world access permissions. By setting
true, server owners can prevent players from warping to certain worlds by denying the permission
Added a way to prevent homes being used/modified if too many are set.
There was an exploit where if a player’s home count was reduced, the player could still overwrite homes and keep the higher number. By default, in this scenario now, Nucleus will not allow players with too many homes from modifying and warping to homes until some are deleted, but for the scenario that servers might want to keep this behaviour, there is a new option in
homes.prevent-home-count-overhang - set this to
false to retain the existing behaviour.
Developers - API updates
Dependency (1.12.2): ‘io.github.nucleuspowered:nucleus-api:1.2.0-PR2-S7.0’
[PR2] Updates for the Sponge Cause Stack Manager (CSM)
There are a few things to be aware of:
- We’ve kept the
Cause parameter on API methods where the API method can be called async. The Sponge CSM only works on the main thread. Read the Sponge Javadocs for API 7 for how to create causes off the main thread (look at
- If a player’s chat is caused by
sudo, note that the root cause will NOT be the
sudo'd player, but the player who caused the chat (who ran the sudo command). Check for the
EventContexts.PLAYER_SIMULATED key for the
GameProfile of the simulated player. Nucleus will look for this context too.
- Nucleus will add the (Nucleus)
EventContexts.SHOULD_FORMAT_CHANNEL context when Nucleus will not format chat. Your plugins can also add this context when you send a chat message that you don’t want Nucleus to format the chat - if you want to use the ID, it’s
Developers can now inspect and change a player’s invulnerability status (often referred to as “god mode”)
Large update to the Kit service
Kits now contain the name of the kit, and back end changes now affect how kits should be saved. Existing integrations will still work, but note that there are a fair few deprecations. Such methods will be removed in Nucleus 2.0, when that comes to be.
