Does an example repo exists with all three of compose desktop (configured to build for every OS), android and web with common sources without having to use subprojects?

Official repo examples:
https://github.com/JetBrains/compose-jb/tree/master/experimental/examples
Notice they are under experimental.
You can search on GitHub, there are a couple of other good setups too. I am working on one setup right now, planning to add iOS soon.

Anyone welcome to participate. The idea is getting familiar with the technology by doing an App at the same time.

Now, the subproject part, I think you won't find anything like that out there. The multi platform nature of the project requires that. Notice any project of this magnitude relies a lot on abstractions and dependency provition rather than actual implementation and direct call of a platform specific API. Pretty much you got to abstract platforms away

I've been working on adapting chat-mpp, but I'm getting the following error, and google doesn't yield any results:

Could not create an instance of type org.jetbrains.kotlin.gradle.plugin.mpp.KotlinAndroidTarget.
> Could not generate a decorated class for type KotlinAndroidTarget.
   > com/android/build/gradle/api/BaseVariant

Humm, I see. I will go through the pain soon. Are you using Android Studio or Intellij

[Pablichjenkov]

I’ve noticed that Android Studio picks up Android modules better

Just ran into the "Could not create an instance..." error message myself, and a Google search trying to find the answer led me to this thread.

(Note: I'm using IntelliJ Community Edition, not Android Studio)

However, I then fixed it, so I thought I'd paste my solution here, for any future devs who also hit it:

1. Add the Android Library (or Application) Plugin to your plugins block. (I just used the latest version available, from here: https://developer.android.com/studio/releases/gradle-plugin)
2. Add google() to your pluginManagement block, in your settings.gradle file (next to where gradlePluginPortal is declared)

At this point, I got passed the original error but there are more.

I'm not 100% sure what I'm doing, but I'll include my steps here as I do my best to figure things out. If an Android dev sees I'm doing something wrong / missing something, please don't hesitate to call that out.

1. Add a top-level android { ... } block with a compileSdk and namespace set.
2. Add the following line to my gradle.properties file: kotlin.mpp.androidSourceSetLayoutVersion=2 (I got a warning message suggesting it)
3. Configure the android target in the kotlin block to publish a release artifact (since in my project, I'm building a multiplatform library that can be consumed by Android):

kotlin {
  android {
    publishLibraryVariants("release")
  }
}

4. Add an AndroidManifest.xml file under src/androidMain

Edit: Here's the final diff of the change I made, in case anyone wanted to reference it.
