Facing this issue while adding clickable method in compose view
org.jetbrains.kotlin.backend.common.BackendException: Backend Internal error: Exception during IR lowering
kotlin version : '1.4.32'
compose version : '1.0.0-beta09'

Let me know if anyone has any clue how to resolve this.

Did you disable the warnings around which kotlin version you're using? 🙂

[Prashast Rastogi]

Actually I got no such warnings while using above combination of versions.

[Prashast Rastogi]

@Adam Powell If I use kotlin version 1.5.2 then I got a compilation error stating to use 1.4.32 so I downgraded my version.
Been stuck for hours, someone please help me out here.

[Adam Powell]

Use kotlin 1.5.10

[Prashast Rastogi]

@Adam Powell Then it doesn't compile and throws this compilation error

e: This version (1.0.0-beta07) of the Compose Compiler requires Kotlin version 1.4.32 but you appear to be using Kotlin version 1.5.10 which is not known to be compatible.

[Adam Powell]

Use Compose beta09 and Kotlin 1.5.10 together

[Prashast Rastogi]

Yeah I use 1.0.0-beta09 but during error it shows (1.0.0-beta07) , and the issue still persists

[Adam Powell]

Check that you've specified the right version of the compose compiler plugin as shown here https://developer.android.com/jetpack/androidx/releases/compose-compiler#declaring_dependencies

Can you share your gradle files

[Francesc]

I have the same problem after updating to beta09 and Java 11, it complains beta07 requires 1.4.32, when there is no reference t beta07 in the gradle files.

I have a sample project with a branch with the update to beta09 showing the error here

[Ian Lake]

@Francesc - looks like you're missing the kotlinCompilerExtensionVersion in your build.gradle.kts files, you do need that line as per the line Adam shared

[Francesc]

thanks, I'll look into that in a bit

[Francesc]

that fixed it for me, thanks again for pointing me in the right direction. I notice though that kotlinCompilerVersion is marked as deprecated

[Francesc]

that's what my gradle file was missing, I had only kotlinCompilerExtensionVersion in there

[Prashast Rastogi]

@Ian Lake @Adam Powell I have all the declarations in place, still this same issue occurs

e: This version (1.0.0-beta07) of the Compose Compiler requires Kotlin version 1.4.32 but you appear to be using Kotlin version 1.5.10 which is not known to be compatible.

[Prashast Rastogi]

If i rollback to version 1.4.32 then it works fine until I start adding clickable to compose widgets where it starts throwing org.jetbrains.kotlin.backend.common.BackendException: Backend Internal error: Exception during IR lowering

[Se7eN]

Just a guess but maybe you're using different compose versions for different compose dependencies?

[Ian Lake]

If you have any error message saying Compose Compiler beta07, then no, you haven't added those lines in the right place as if you did, you'd be using beta09 🙃 Do you have multiple modules and did you update them all?

[Prashast Rastogi]

It finally worked, thanks a lot guys 🙌
