I published an update to an Intellij plugin of mine just a few months ago, but when I went back to work on the same projects again recently I simply couldn't get it to build anymore.

It seems that a lot of the stuff associated with the Gradle build needed to be updated, so I took care of that as best as I could, and now I can build once again. A test deployment of the plugin worked too, so the code is now basically in good working order.

But I had to leave out my old changeNotes to get to this point. This function (which used to work properly) is now declared undefined. The function provides a list of change notes which can be viewed from within the IDE and on the Market Place web page for the plugin.

I think this functionality might now reside in .jetbrains.intellij.platform, but I can't find a way to define intellijPlatform that which doesn't break my build in the attempt.

Here's my current build.gradle.kts

plugins {
  id("java")
  id(".jetbrains.kotlin.jvm") version "1.9.21"
  id(".jetbrains.intellij") version "1.16.1"
  // id(".jetbrains.intellij.platform") version "2.0.1"
}

group = "com.my-domain"
version = "1.0.6"

// Configure Gradle IntelliJ Plugin
// Read more: .html
intellij {
  version.set("2023.1.5")
  type.set("IC") // Target IDE Platform

  plugins.set(listOf(/* Plugin Dependencies */)) // Haven't figured out what dependencies, if any, should go here
}

repositories {
  mavenCentral()

//  intellijPlatform { // Flagged as undefined unless I comment it out
//    releases()
//    marketplace()
//  }
}

tasks {
  // Set the JVM compatibility versions
  withType<JavaCompile> {
    sourceCompatibility = "17"
    targetCompatibility = "17"
  }
  withType<.jetbrains.kotlin.gradle.tasks.KotlinCompile> {
    kotlinOptions.jvmTarget = "17"
  }

  patchPluginXml {
    sinceBuild.set("231")
    untilBuild.set("241.*")
  }

  signPlugin {
    certificateChain.set(System.getenv("CERTIFICATE_CHAIN"))
    privateKey.set(System.getenv("PRIVATE_KEY"))
    password.set(System.getenv("PRIVATE_KEY_PASSWORD"))
  }

  publishPlugin {
    token.set(System.getenv("PUBLISH_TOKEN"))
  }
}

tasks.getByName<.jetbrains.intellij.tasks.PatchPluginXmlTask>("patchPluginXml") {
    // Commented out because it doesn't work anymore as is.
//  changeNotes("""
//    <h2>1.0.5</h2>
//    <ul><li>Blah, blah, blah.</ul>
//    <h2>1.0.4</h2>
//    <ul><li>Blah, blah, blah.</ul>

//    <ul><li>Blah, blah, blah.</ul>
//    <h2>1.0.0</h2>
//    <ul><li>First release</li></ul>
//"""
//  )
}

When it comes to trying to include ".jetbrains.intellij.platform", I get errors about conflicting class definitions, or I'm told I need to use Gradle 8.5 (which I can't figure out how to do, and probably would be barking up the wrong tree anyway), or I get an error like this:

Any ideas how to fix the problems I'm having here? I'm using IDEA 2023.3.2 on macOS 15.3.

I found a way to put my change notes back. It doesn't actually answer my questions about where definitions for intellijPlatform and changeNotes can be found, but it does solve the basic problem that prompted those questions in the first place.

I can simply put my change notes into plugin.xml in very much the same way I had already had a <description> of the plugin in that file.
