# compose

I have a project that uses moshi and I'm trying to enable compose. So far I updated kotlin to 1.4, agp to 4.2.0-alpha10, gradle to 6.6.1,

When I do the above, my app runs fine, it's only when I add

buildFeatures {
    compose true
}
composeOptions {
    kotlinCompilerExtensionVersion MyVersions.compose_version //this id defined as val compose_version = "1.0.0-alpha02"
    kotlinCompilerVersion '1.4.0'
}

I get an error when my app runs due to moshi/kotlin reflection?

Has anyone come across this? I've looked in issuetracker to no avail.

I ran into some issues using Kotlin Serialization because of Compose. I put the Kotlin Serialization stuff in a separate module and that fixed it for me. So maybe a similar approach could work for you 🤔

[Colton Idle]

That does not sound fun. Did you run across any bug reports or anything I can star/thumbs up?

[Brett Best]

Well in my case the build would just keep going on forever, really frustrating lol

I ended up finding this: https://github.com/Kotlin/kotlinx.serialization/issues/968

[Brett Best]

I only had to put the data classes that used the @Serializable annotation in that module

Is this the latest moshi (1.10.0)?

[Colton Idle]

@efemoney yes, I upgraded to latest moshi as it looked like the root of the issue was from there.
