Hi,
i've been updating from kotlin 1.9.21 to 2.1.0 - but faced https://kotlinlang.slack.com/archives/C3PQML5NU/p1734682764859439
so i tried using 2.0.21 -> migrated the compose compiler to the AGP.
now getting:

Unsupported plugin option: androidx.compose.compiler.plugins.kotlin:traceMarkersEnabled=true

i do not specify this option in any of my code. so seems a (transitive) dependency is using that - but how would i discover that?

[tapchicoma]

There is no straightforward way. Possible approach could be trying to disable one-by-one dependencies that may configure it.

[Christoph Wiesner]

thanks for your answer - that's gonna be a pain 😬

[tapchicoma]

though traceMarkersEnabled should be supported by compose plugin 🤔

[Christoph Wiesner]

could it be due to the fact that composeOptions {} are now at the root-level of the gradle file rather than nested in android { composeOptions {} } ?

[tapchicoma]

yeah, all compose options should be configured now in root composeOptions {} DSL

[Christoph Wiesner]

so all dependencies need to use the updated DSL, right?

[tapchicoma]

right

[Christoph Wiesner]

i've found the causing dependency/setup 🥳

for anyone facing that issue - check if you're using app.cash.molecule this needs a migration for kotlin 2.0.0
sadly it only surfaced through this error but fixed now
