Updating from 1.18.2 to 1.19.2

Before you do anything, please make a backup so you can roll back if something goes wrong. Be careful to follow these steps in order!

If you have a 1.16 mod that you want to update to 1.19, you must also apply the code changes between 1.16 and 1.18. Consult the updating from 1.16 to 1.17 tutorial and the updating from 1.17 to 1.18 tutorial.

Update build.gradle​

Change to the 1.19 mappings

mappings channel: 'official', version: '1.19'

Change to minecraft 1.18 and the newer version of forge in the dependencies block 

minecraft 'net.minecraftforge:forge:1.19-41.0.1'

You will have to run the gradle command to generate your IDE run configurations again (genIntellijRuns or genEclipseRuns).

Update mods.toml​

open your src/main/resources/META-INF/mods.toml file.

change the forge loader version to 

loaderVersion="[41,)"

change the required version for the minecraft dependency to 

versionRange="[1.19,1.20)"

and the required version for the forge dependency to 

versionRange="[41,)"

Code Fixes​

There are a few changes to make in your code. For example,

  • the Component class hierarchy has is changed. new TextComponent("string") -> Component.literal("string"). new TranslatableComponent("thing.name") -> Component.translatable("thing.name")
  • registry events have changed. If you're automatically registering block items, as i do, revisit the relevant section of the blocks tutorial
  • Some methods that previously took a Random instance, now want a RandomSource (it just became an interface). Block#randomTick(BlockState, ServerLevel, BlockPos, Random) becomes Block#randomTick(BlockState, ServerLevel, BlockPos, RandomSource)
  • if you're using an apple silicon computer, you need to add a new mixin, read apple silicon tutorial or you will get an UnsatisfiedLinkError

Later versions​

The rest of the tutorials on this site are for 1.19.2, NOT 1.19.3 or 1.19.4. Mojang changed how they deal with breaking changes in minor versions so some stuff will be different. I'll probably update it at some point but for now see these resources for an overview of changes.
