If you want to test it:

gradle.properties:

org.gradle.configuration-cache=true
kotlin.stdlib.default.dependency=false

build.gradle.kts:

import org.jetbrains.kotlin.gradle.dsl.JvmTarget
import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

plugins {
  id("java")
  id("org.jetbrains.kotlin.jvm") version "2.3.0"
  id("org.jetbrains.intellij.platform") version "2.16.0"
}

java {
  toolchain {
    languageVersion.set(JavaLanguageVersion.of(25))
  }
}

group = "com.intellij.guice"
version = "261.0"

repositories {
  mavenCentral()
  intellijPlatform {
    defaultRepositories()
  }
}

    bundledPlugin("org.jetbrains.kotlin")
    testFramework(TestFrameworkType.Platform)
    testFramework(TestFrameworkType.Plugin.Java)
    testFramework(TestFrameworkType.JUnit5)
  }
   testImplementation("com.google.truth:truth:1.4.2")
}

java {
  sourceSets.getByName("main") {
    java {
      srcDir("gen")
      srcDir("src")
    }
    kotlin {
      srcDir("gen")
      srcDir("src")
    }
    resources {
      srcDir("resources")
    }

    java {
      srcDir("test")
    }
    kotlin {
      srcDir("test")
    }
  }

}

kotlin {
  jvmToolchain(25)
}

intellijPlatform {
  pluginConfiguration {
    ideaVersion {
      sinceBuild = "261"
    }

    changeNotes = ""
  }
}

tasks {
  // Set the JVM compatibility versions
  withType<JavaCompile> {
    options.release = 25
    sourceCompatibility = "25"

Indentation seems to be off, but I don't know which code style is used at JetBrains and how to apply it to all files at once. Sorry.

Yann Cébron (@YannCebron), FYI

Andrey Belyaev (@belyaev-andrey), do you want to take a look? :)
I'm sure there are some issues introduced in the inspections, but the model part was significantly improved in terms of supported features, performance and languages.

Works great with Kotlin: using java 21, gradle 8, kotlin 2.

Thanks!
