I got this error in the linked project... I am using the latest compose build that support k2 in build 2.0.0-Beta3... I tried updating AGP to the latest alpha, but the error is the same...

kotlin version: 2.0.0-Beta3

it seems this has been reported, but it is tagged as obsolete.. how to proceed ?

Make sure you use compatible builds, probably beta3 is the most suitable here

Compose doesn't track Kotlin dev versions yet, so you get binary incompatibilities when running the plugin.

[juliocbcotta]

I used the compose build released with support to beta3

[shikasd]

Ah, thanks for confirming
I'll take a look at this tomorrow

[shikasd]

I just tested beta3 with Compose compiler 1.5.9-dev-k2.0.0-Beta3-7c5ec6895a0 and it compiles for me
It does look like Kotlin compiler had a binary incompatible change in that area, but the Compose artifact is rebased correctly

[juliocbcotta]

So, am I misconfiguring anything? There is no bug to report then?

[shikasd]

I am not sure what your config is, but the version of Compose compiler seems to be misconfigured

[juliocbcotta]

OK, I will double check.

[juliocbcotta]

Ok, I think I found it. thanks for the help
