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).

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,)"

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
