building mod does not include mcmod.info (1.12.2) - minecraft

Question

posting here as 1.12.2 is no longer officially supported by forge,
trying to build my first mod and I'm having troubles getting it to be detected by gradle
build.gradle
buildscript {
repositories {
// These repositories are only for Gradle plugins, put any other repositories in the repository block further below
maven { url = 'https://maven.minecraftforge.net' }
mavenCentral()
}
dependencies {
classpath group: 'net.minecraftforge.gradle', name: 'ForgeGradle', version: '5.1.+', changing: true
}
}
apply plugin: 'net.minecraftforge.gradle'
group = 'AvalonMods'
version = '0.0.1-SNAPSHOT'
java {
archivesBaseName = 'RuneTech'
toolchain.languageVersion = JavaLanguageVersion.of(8)
}
minecraft {
// The mappings can be changed at any time and must be in the following format.

//
// You must be aware of the Mojang license when using the 'official' mappings.

// }
}
dependencies {
// Specify the version of Minecraft to use. If this is any group other than 'net.minecraft' it is assumed
// that the dep is a ForgeGradle 'patcher' dependency, and its patches will be applied.
// The userdev artifact is a special name and will get all sorts of transformations applied to it.

jar {

"Specification-Version" : "1", // We are version 1 of ourselves
"Implementation-Title" : project.name,
"Implementation-Version" : project.jar.archiveVersion,
"Implementation-Vendor" : "Kital_Stargazer",
"Implementation-Timestamp": new Date().format("yyyy-MM-dd'T'HH:mm:ssZ")
])
}
}
jar.finalizedBy('reobfJar')
mcmod.info
[
{
"modid": "runetech",
"name": "Rune Tech",
"description": "A technological approach to magic",
"version": "${version}",
"mcversion": "${mcversion}",
"url": "",
"updateUrl": "",
"authorList": [
"Kital_Stargazer"
],
"credits": "Inspired by: Thaumcraft (v4.2.3.5), Immersive Engineering, Embers, and more",
"logoFile": "",
"screenshots": [],
"dependencies": []
}
]
it otherwise works it's just the mcmod.info that is being stubborn.
mcmod.info is in src/main/resources, build.gradle is (to my knowledge) correctly formatted as well as mcmod.info
the mod is otherwise very bare bones at the moment so there is little that could be causing an issue

Answer 1

If you use IntelliJ IDEA, then add to the end of the file build.gradle
apply plugin: 'idea'
idea {
module {
inheritOutputDirs = true
}
}
subprojects {
apply plugin: 'idea'
}
task prepareAssets(type: Copy) {
group = 'build'
from project.file('src/main/resources')
into project.file('build/classes/java/main')
}
classes.dependsOn(prepareAssets)
This should help the collector find the resources of your mod.
