Hopefully tossing out a line here for some insight…
I am making a java-gradle-plugin and I need it to have reference to some of the classes inside of the multiplatform plugin.
I have the plugin working 100% if I use the kotlin("jvm") plugin, but as soon as I switch to multiplatform I get class implementation not found in the plugin, and unzipping the output jar in the gradle cache, has none of the java components, just meta data.

Is anyone aware of how I can override the publishing of the multiplatform targets (atleast one is required) so that it can use the plugin output rather than the multiplatform output? I Only need access to the classes from the multiplatform plugin, no outputs from it itself (or publishing for that matter)

I think you plugin should add compileOnly dependency for kotlin gradle plugin:

compileOnly(kotlin("gradle-plugin", <plugin_version>))

I currently have my implementation(kotlin("gradle-plugin", version)) in a buildSrc, so I would need to re-add to classpath anyways?

[Benjamin Charais]

I guess I’m unsure what the compileOnly would fix ehre.

[tapchicoma]

let me clarify - you are writing Gradle plugin and want to use some classes from kotlin Gradle plugin?

[Benjamin Charais]

Specifically I would like to use classes such as:

org.jetbrains.kotlin.gradle.dsl.KotlinMultiplatformExtension

org.jetbrains.kotlin.gradle.dsl.plugin.mpp.Framework

org.jetbrains.kotlin.gradle.tasks.FatFrameworkTask

[Benjamin Charais]

Classes implemented by the plugin, but don’t actually need the plugin.

[tapchicoma]

then add compileOnly dependency into plugin module dependencies { .. } block and wrap code that calls KMMGP classes with project.plugins.withId("org.jetbrains.kotlin.multiplatform") { // your code here }.

Why compileOnly ? Then you plugin will not bring as a dependency specific version of Kotlin Gradle Plugin, but still will react if user will explicitly add it to the buildscript.

I definitely understand your point now. Thank you. I knew that there was a way to have proper reference. Thank you
