[1.12.2] Problem with SpongeForge / mixin as library from a cloned repo

Recommended Posts

So I am trying to run (in Eclipse) some code I cloned for a SpongeForge hybrid mod. It is a private repository so I can't post much of it here, but I have a general question. The gradle/maven from the build.gradle seems to properly download SpongeForge and related things like "mixin" and I can see it in my referenced library just fine.

 

The build.gradle looks like:

buildscript {
    repositories {
        jcenter()
        maven {
            name = "forge"
            url = "https://files.minecraftforge.net/maven"
        }
        maven {
            url = "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath "net.minecraftforge.gradle:ForgeGradle:2.3-SNAPSHOT"
        classpath "gradle.plugin.org.spongepowered:spongegradle:0.8.1"
        classpath "com.github.jengelman.gradle.plugins:shadow:2.0.2"
    }
}

apply plugin: "net.minecraftforge.gradle.forge"
apply plugin: "org.spongepowered.plugin"
apply plugin: "com.github.johnrengelman.shadow"

version = modVersion
group = modGroup
archivesBaseName = modBaseName

minecraft {
    version = project.forgeVersion
    runDir = "run"

    // the mappings can be changed at any time, and must be in the following format.
    // snapshot_YYYYMMDD   snapshot are built nightly.
    // stable_#            stables are built at the discretion of the MCP team.
    // Use non-default mappings at your own risk. they may not always work.
    // simply re-run your setup task after changing the mappings to update your workspace.
    mappings = project.mcpVersion
    // makeObfSourceJar = false // an Srg named sources jar is made by default. uncomment this to disable.
}

repositories {
    mavenCentral()
}

tasks.withType(JavaCompile) {
    options.encoding = 'UTF-8'
}

dependencies {
    compileOnly 'org.spongepowered:spongeforge:1.12.2-2611-7.1.0-BETA-2931'
    compile 'org.mongodb:mongodb-driver:3.4.3'
}

processResources {
    // this will ensure that this task is redone when the versions change.
    inputs.property "version", project.version
    inputs.property "mcversion", project.minecraft.version

    // replace stuff in mcmod.info, nothing else
    from(sourceSets.main.resources.srcDirs) {
        include "mcmod.info"

        // replace version and mcversion
        expand "version": project.version, "mcversion": project.minecraft.version
    }

    // copy everything else, thats not the mcmod.info
    from(sourceSets.main.resources.srcDirs) {
        exclude "mcmod.info"
    }
}

build.dependsOn(shadowJar)

 

However, when I run the client run configuration I get the following error:

The key error seems to be that it is saying there is "func_70932_a_ does not exist in target interface net.minecraft.entity.IMerchant"

 

However, if I check MCPBot that function does exist and is related to merchant interface.

 

Other people who clone the repository and run it in IntelliJ say it works. However, they also say I need to separately download the SpongeForge JAR and put it in my "mods" folder. However, I feel that is not correct because I already see it in my referenced libraries (Maven has already downloaded it) and also I would need a deobfuscated version of the JAR which I can't find -- I think they mean I need to download it if I actually build the mod and try to run it normally. I'm trying to run inside Eclipse using the Run Configuration.

 

So a couple questions:

- There is also the earlier warning "Unable to instantiate org.fusesource.jansi.WindowsAnsiOutputStream". Is that a problem, and if so how to fix?

- If I already have the JAR downloaded and referenced automatically with gradle/maven, do I really also need to download the JAR separately as well in order to run in Eclipse?

- Why would mixin be having trouble finding a function which should exist?

- Any other tips for using SpongeForge library?

I'd like to know if this is a generic thing with using libraries, or specific to mixin -- If the build.gradle has downloaded the library and it shows up properly in my referenced libraries, is there any need to separately "install" the library JAR or manually do anything in the build path?

    • I made a block entity in forge 1.20.1, I want to prevent hopper from taking input slot item, i tried to override the extractItem method, it prevented hopper from taking input slot item, but the player also unable to take/change the item in input slot unless the slot is empty. public class FluidSeparatorBlockEntity extends BlockEntity implements MenuProvider { private static final int INPUT_SLOT = 0;

    • No dice. Unfortunately this fix didn't work, thank you though.
    • Maybe you need a rayon mod. https://www.curseforge.com/minecraft/mc-mods/rayon
    • Not sure what's going on the logs are making even less sense than usual to me. Any help would be much appreciated.   https://paste.ee/p/KBHyP#s=0
