I am having issue with mixin refmap generation !

[DarthVaderxq]

Previously i used Forge Gradle in which i was generating mixin refmaps in jar / root / mixin

but now I switched to NeoForge Legacy Mod Dev Gradle

so the issue is it wont let me generate in the path that i specify to it with rather than its generating in the root !

java mixin { add (sourceSets.main, "mixin/${mod_id}.mixins.refmap.json") config ("mixin/${mod_id}.mixins.json") config ("mixin/${mod_id}.mixins.forge.json") }

the forge:build --info says

groovy Contributing refmap (mixin\mymod.mixins.refmap.json) to mymod-forge-1.18.2-1.0.0.jar in project ':forge'

or should i just apply the sponge mixin plugin and use it ?

I am on 1.18.2, 1.19.2, 1.20.1 using NeoForge Legacy Mod Dev Gradle v 2.0.123

i was also having the same issue when i switched to Loom 1.14 from 1.7 so i fixed it useLegacyMixinAp = true

i would like to know the fix and whats stopping it from generating it there if the path is given and we can see it in log

Thank you for your time and help !

this is my minimal forge: build.gradle

plugins {
    id 'multiloader-loader'
    id 'net.neoforged.moddev.legacyforge'
}


legacyForge {

    version = "${minecraft_version}-${forge_loader_version}"


    mixin {
        add (sourceSets.main, "mixin/${mod_id}.mixins.refmap.json")
        config ("mixin/${mod_id}.mixins.json")
        config ("mixin/${mod_id}.mixins.forge.json")
    }


    runs {
        client {
            client()
        }
        datagen {
            data()
            programArguments.addAll '--mod', project.mod_id, '--all', '--output', file('src/generated/resources/').getAbsolutePath(), '--existing', file('src/main/resources/').getAbsolutePath()
        }
        server {
            server()
        }
    }

    mods {
        "${mod_id}" {
            sourceSet sourceSets.main
        }
    }

}


dependencies {
    annotationProcessor("org.spongepowered:mixin:0.8.5-SNAPSHOT:processor")
}


// Jar
tasks.named("jar", Jar).configure {
    finalizedBy('reobfJar')

    manifest.attributes([
            "MixinConfigs": "mixin/${mod_id}.mixins.json,${mod_id}.mixins.forge.json"
    ])
}```

While MDG generates the refmap in the folder, it uses Jar#from to include it which does not account for the folder. You'll have to rename the refmap to place it in the folder within the jar task (i.e. jar { rename ... })
