[gildor]

build with --stacktrace

[gildor]

it looks that you have some compiler plugin which doesn’t work with Kotlin 1.4 (compiler plugins are not stable and changed in 1.4

I know but what should i do?

[gildor]

what --stacktrace is showing?

[gildor]

what kind plugin is failing?

[gildor]

which version of compose you use?

[Mehmet Peker]

Compose version :

1.0.0-alpha01

Kotlin version 1.4.0.I got this error 1.3.60.I searching this error at web answer is what find at google is error related with annotation processor(Room or dagger)

[gildor]

Room works fine with compose in this sample app by Romain

[gildor]

Probably some code in your app uses old version of Kotlin compiler or old version of compose

or there is another issue, what is in your stacktrace?
