Seeing this compiler BackendException on AS when building a multi module KMM project which uses Jetpack compose

org.jetbrains.kotlin.backend.common.BackendException: Backend Internal error: Exception during IR lowering

and this as render problems when preview tries to load in between

java.lang.NoSuchMethodError: 'void androidx.compose.material.TextKt.Text...'

Found a few other people who had the same issue here, on the issuetracker and even on SOF but none of the solutions that worked for them, worked for me unfortunately.

More details in the 🧵 .

Using -

Android Studio Bumblebee | 2021.1.1 Beta 1
gradle plugin - 7.1.0-beta01 | wrapper - 7.2
kotlin - 1.5.31
compose - 1.1.0-alpha06

Project structure-

Proj
----buildSrc
----kmmApp
----------androidApp // includes compose
----------iosApp
----------shared
-------------androidMain
-------------iosMain
-------------commonMain
----kmmLib1
----------androidMain // includes compose
----------iosMain
----------commonMain
----kmmLib2
----------androidMain
----------iosMain
----------commonMain
----settings.gradle.kts // include(":kmmApp:shared", ":kmmApp:androidApp", "kmmLib1", "kmmLib2")

So far I’ve tried -
• Since I was using buildSrc, added the fix suggested here
• added this to all modules

buildFeatures.compose = true
composeOptions.kotlinCompilerExtensionVersion = "1.1.0-alpha06"

• Multiple rounds of clean, rebuild and Invalidate caches, even a system reboot to see if I’d get lucky.

I think there’s a decent chance this is just a compose issue and not a kmp thing. Maybe ask in #compose.

Will do. Thanks @russhwolf. 🙂
