/reload command in Minecraft

/reload rereads all enabled data packs: functions, recipes, loot tables, advancements, tags, predicates and other data files. It is the command you run after every edit while building a data pack, so you can test changes without leaving the world.

Syntax

/reload

Examples

Reload after editing a pack

/reload

Rereads every enabled data pack and runs the minecraft:load functions again.

Java 26.3

Check what is loaded

/datapack list enabled

Lists the enabled packs, handy to confirm that a new pack was picked up.

Java 26.3
Build your command

Fill in the fields, then copy the command.

 Command generator

What /reload does

The game answers "Reloading!" and loads the packs again. Functions in the #minecraft:load tag run once more afterwards, so a pack can set up its objectives again. If loading fails, you get "Reload failed; keeping old data" and the previous data stays active. Errors in single files go to the game log, not to chat. A new pack placed in the datapacks folder is picked up as well, unless it was disabled before.

Limits

  • World generation data such as biomes, dimensions or structures, and registry content such as enchantments, only change after the world is reopened or the server restarts.
  • Resource packs are not part of /reload: they reload on the client with F3 + T.
  • It reloads every pack for the whole server at once; with large packs, expect a short lag spike, so avoid it during busy sessions.
  • To turn packs on or off, use /datapack, then test your work with /function.

/reload: FAQ

Does /reload reload resource packs?

Why are my new biomes missing after /reload?

World generation data is only read when the world loads. Save and quit, then reopen the world or restart the server.
