I'm having an issue getting gradle to build a KMM ...

# multiplatform

[Brandon Chapman]

I'm having an issue getting gradle to build a KMM app. Targeting Android, Desktop, Server. Whenever I add sqldelight plugin to the composeApp build.gradle.kts it spits out this error:

Using 'compilerOptions(KotlinCommonCompilerOptions.() -> Unit): Unit' is an error. Kotlin target level compiler options DSL is not available in this release!

[Arsildo Murati]

what kotlin version are you running?

[Arsildo Murati]

kotlin("plugin.serialization") version "1.9.10" why is this separate ?

[Arsildo Murati]

of the kotlin version

[Arsildo Murati]

Afaik this block here compilerOptions {
jvmTarget.set(JvmTarget.JVM_11)
}

[Brandon Chapman]

I have no idea what I'm doing. New to everything with developing on this platform

[Arsildo Murati]

is after kotlin 2.0

[Arsildo Murati]

I think this is where your error comes from

[Brandon Chapman]

I have experience with Android development back in 2018. Java and xml and it'll all look ancient compared to 2024 dev with these toolings. Any help would be appreciated

[Arsildo Murati]

you need to upgrade to k2.0 to bypass this issue

[Arsildo Murati]

or revert the compiler option block

[Brandon Chapman]

Okay. I'll look into upgrading Kotlin. Thanks

[Arsildo Murati]

kotlin("plugin.serialization") version "1.9.10" move this to alias() block from your libs file

[Arsildo Murati]

link the kotlin version from the libs file

[Brandon Chapman]

I don't see an alias() block

[Arsildo Murati]

alias(libs.plugins.kotlinMultiplatform)
alias(libs.plugins.androidApplication)
alias(libs.plugins.jetbrainsCompose)
alias(libs.plugins.compose.compiler)
kotlin("plugin.serialization") version "1.9.10"
id("app.cash.sqldelight") version "2.0.2"

[Brandon Chapman]

That's the same block

[Arsildo Murati]

just have one source of truth for you kotlin version

[Arsildo Murati]

inside your libs file

[Arsildo Murati]

where the versions are located

[Brandon Chapman]

kotlin = "2.0.0" It seems I'm already on 2.0 so it sounds like I should try to use that version for serialization

[Brandon Chapman]

Will try now

[Brandon Chapman]

Resolved. Build succeeds. Thank you 👍
