Add Kotlin Buildscripts + Add Kotlin Buildscript Support to Testing + Update Gradle Plugins, Gradle and MinecraftForge by Codetoil · Pull Request #6 · MinecraftForge/MDKExamples

Codetoil · 2026-02-26T22:58:53Z

Lex mentioned that the Kotlin Buildscript needed to be added to the testing framework. I went ahead and did that.
While I was there, I bumped the Gradle Plugins, Gradle and MinecraftForge, since they should probably be up to date.

Update Gradle Plugins and MinecraftForge

This doesnt actually seem to add any kotlin examples
Nore does it seem to of actually run the _internal updates.
What is the goal of this PR?

Codetoil · 2026-03-01T05:51:10Z

It adds the existing kotlin buildscript into the _internal testing framework. Plus I made some modifications to it to extend its capabilities.

Codetoil · 2026-03-01T05:51:44Z

If you want me to add the kotlin examples in the same PR, I could, but that'll take me some time to make.

LexManos · 2026-03-01T06:00:03Z

Worth doing yes, and like I said, the updateBuilds task doesnt seem to of been run because the current projects output a range, which is not what the code does.
Jonathan changed things to a range after I wrote that task and never updated it.

Codetoil · 2026-03-01T06:20:30Z

I did actually run it though. I modified the task to output a range since that what I thought you wanted.

LexManos · 2026-03-01T06:21:19Z

Oh my bad, forgot it was hardcoded, thought I had it pick from that subproject's version. Im an idiot.
I'll try and remember to look at this tomarrow. But yes, having a kotlin version of each example is the overall goal.

_internal/settings.gradle

+        [version: '[7.0.10,8.0)', id: 'net.minecraftforge.gradle'],
+        [version: '5.0.3', id: 'net.minecraftforge.accesstransformers'],
+        [version: '0.2.3', id: 'net.minecraftforge.jarjar'],
+        [version: '1.0.2', id: 'net.minecraftforge.renamer'],


Why did you delete the paths that completely breaks the include build functionality...

It doesn't. Paths aren't used at all in the code.

Actually nevermind they are my bad

obfuscation/fg7-kotlin/build.gradle.kts

+
+    publications.register<MavenPublication>("mavenJava") {
+        from(components.named("java").get()) // Publish the normal jar
+        artifact(tasks.named("renameJar").get()) // Publish the renamed jar in addition


The .get() shouldn't be needed. As it forces the task to be resolved at evaluation time. Breaking lazy configuration.

Doesn't compile in Kotlin otherwise.

What do we need to do to make kotlin happy with gradle's lazy tasks?

LexManos · 2026-03-02T22:36:43Z

Why did you move the internal project up a level? this removes the ability to add a fg6 version

LexManos · 2026-03-02T22:44:51Z

As for actually running the tests, they are broken
I am not sure how the existing tasks got broken but it did.
Also may be worth adding a gradle cache redirect to make each sub-project have its own separate cache (and this no inter-project overlaps)
I think the traditional's are broken because you bumped the minecraft/forge version without updating the code. No idea why you bumped the forge version its not needed. This project isn't about chasing MC/Forge. Its about testing the toolchains and giving examples of the basics. If we want to add more Minecraft specific examples we'd make projects like game-content/blocks/furnace/1.12.2 and game-content/blocks/furnace/1.20.1

You run into the same issue in the original codebase if you use the gradle build task for the mdkexamples gradle project. (Unless it's from the port from FG 7.0.0-rc.5 to [7.0.2,8.0))

Codetoil · 2026-03-03T06:15:34Z

Running the build tasks per-gradle project does work

LexManos · 2026-03-03T19:49:37Z

There are still issues with lazy configuration and the published artifacts but im getting tired of arguing about this.
