Updating 1.18.2 to 1.19.2, errors when loading gradle changes, possibly caused by mappings

[Myxtro]

I'm updating my project to 1.19.2 from 1.18.2. For this I changed my build.gradle. I changed the following things:

I set my dependencies to:

dependencies {
    minecraft 'net.minecraftforge:forge:1.19.2-43.1.25'

    implementation fg.deobf('software.bernie.geckolib:geckolib-forge-1.19:3.1.20')
}

And my mappings to:

mappings channel: 'parchment', version: '2022.09.04-1.19.2'

(I also tried version: 1.1.8.2-2022.05.02-1.19 but that had the same result)

 

I get the following errors when I try to load the gradle changes:
 

- java.lang.IllegalStateException: ProjectScopeServices has been closed
- Start.java:
  - package net.minecraft.client.main does not exist
  - cannot find symbol variable Main
  - package net.minecraft.client.main does not exist
  - cannot find symbol variable Main
- java.lang.IllegalStateException: ProjectScopeServices has been closed
- Could not resolve net.minecraftforge:forge:1.19.2-43.1.25_mapped_parchment_2022.09.04-19.2

I have a feeling this is caused by the mappings but I'm not certain about this.

Any idea what I could do?

Please show your entire buildscript. Forge has changed in 1.19 now using the plugin DSL, hence there is a new method of adding the necessary libraries: https://github.com/ParchmentMC/Librarian/blob/dev/docs/FORGEGRADLE.md.
