Hi!

Trying to add Compose to an existing project as described here: https://developer.android.com/jetpack/compose/setup#add-compose

Adding the Kotlin Android plugin as described on the documentation above:

plugins {
  id 'org.jetbrains.kotlin.android' version '1.4.30'
}

gives me the following error:

[Albert Chang]

If you are specifying Kotlin version in the project-level Gradle build script, you can't specify the version here (meaning you should remove version '1.4.30').

The error message refers to 1.5. There must be another entry somewhere with that version. I would try first creating a sample project with compose and then copy the parts of gradle into your old project

[Albert Chang]

Also if you using Kotlin 1.5.0, it's not yet compatible with compose. The latest compose 1.0.0-beta06 is only compatible with Kotlin 1.4.32.

[Albert Chang]

There is #compose channel. And please put long stack trace in the thread.

Thank you for your response, and sorry for the stacktrace overload. Will post the stracktrace here for future reference. The plugin excerpt above was from the documentation, I have it set up with 1.5.0 in my build.gradle. I had no other specification of the plugin version in my project, but I got it resolved by adding pluginManagement to settings.gradle. Guess it will work for now. I continue experiencing issues, but that is likely due to the compatibility with Compose. Was not aware of that.
