Could not find net.minecraftforge:forge:1.15.2-31.1.1_mapped_stable_60-1.15.

Minecraft Development plugin version: 2019.3-1.3.2 IntelliJ Ultimate version: 2019.3.2 Replicated on 2 windows machines and an arch linux machine

When I create a new project, the project is unable to build and is covered in red errors saying various symbols cannot be resolved. When I go to project structure There is a problem that comes up which says

Library Gradle: net.minecraftforge:forge:1.15.2-31.1.1_mapped_stable_60-1.15 has broken classes path:   C:\Users\josh-laptop\AppData\Local\JetBrains\Toolbox\apps\IDEA-U\ch-0\193.6015.39\jbr\bin\Could not find net.minecraftforge:forge:1.15.2-31.1.1_mapped_stable_60-1.15. [Fix]

I have navigated to the folder and sure enough net.monecraftforge:forge:1.15.2-31.1.1_mapped_stable_60-1.15. is not in it. I don't know if there's a way to manually download this file.

Things I have tried: Make a mod for 1.15.2 and 1.14.4 Invalidate caches / restart Uninstall/reinstall plugin Uninstall/reinstall IntelliJ Uninstall/reinstall JDK Used the following JDKs:

• oracle JDK 8 (windows + linux)
• oracle JDK 11 (windows)
• open JDK 8 (linux) IntelliJ has all the network permissions it would need. I have replicated this issue three times, on two windows machines and my linux machine as I have said.

Here is my build.gradle:

buildscript {
    repositories {
        maven { url = 'https://files.minecraftforge.net/maven' }
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath group: 'net.minecraftforge.gradle', name: 'ForgeGradle', version: '3.+', changing: true
    }
}

apply plugin: 'net.minecraftforge.gradle'

version = modVersion
group = modGroup
archivesBaseName = modBaseName

sourceCompatibility = targetCompatibility = compileJava.sourceCompatibility = compileJava.targetCompatibility = '1.8'

I know there was an IntelliJ update recently. From what I've seen online I thought that the plugin and everything should be updated and fine.

I am very familiar with Python & C++, not as much with Java. I have made a simple mod before, but I would not call myself an expert.

I'll need to double check that the MCP+Forge version logic is still correct.

[oh-noey]

I'm also having this issue, is there a simple way to correct this on the project side manually? I've never attempted to make something in the forge ecosystem before and was hoping to use this to accelerate setting up a dev environment.

I haven’t played around with it super extensively, but it seems like the gradle tasks are all still functional if you manually run them in the correct order, but going through the project structure settings pretty thoroughly I couldn’t get rid of all the errors in the editor. My guess is that you could somehow fix it by tweaking a gradle file, but I haven’t figured out how or why this happens. In the past I’ve had this extension just work perfectly but now I get this issue on every single computer I’ve tried installing it on.

Probably happens because FG3 projects are generated with the wrong Gradle version, downgrading to 4.10.3 fixed it from the few tests I made.

Cuando descargas el MDK, tiene un nombre. En mi caso: forge-1.20.1-47.2.0-mdk Vos tienes que cambiar tienes que utilizar la versión de minecraft(en mi caso es la 1.20.1) y la versión de forge(en mi caso la 47.2.0) que dicen en el rar que descargaste.
