I’m trying to give Compose a try in my current project and I’m facing a problem. I’m trying to use 0.1.0-dev14 version, because in the project I’m using SQLDelight also which is not ready for Kotlin 1.4. Here is the log I’m getting when trying to compile:

e: java.lang.IllegalStateException: Backend Internal error: Exception during code generation

I don’t understand what require 1.4 version

[Brett Best]

Not sure those warnings about the 1.4 version is the cause of the backend internal error

I think you just need to add apiVersion = "1.3" to your kotlinOptions in your gradle config.

Unfortunately adding apiVersion="1.3" didn’t help. I’m posting complete exception log

Are you sure you’ve updated kotlin version?

I don’t remember which one was suggested for dev-14 (probably 1.4-M3), but for 15:

//ext.kotlin_version = "1.3.72"
ext.kotlin_version = "1.4.0-rc"

Thank you for suggestion. I’m quite sure 0.1.0-dev14 requires 1.3.72 and only dev15 requires 1.4 Kotlin’s version, that’s why I stayed on 14, because as I said, for example SQLDelight is not ready yet for 1.4
