today I migrated my KMM project to use compose-viewmodel and started to use koinViewModel<AccountsVM>() but getting below error at every usages

Cannot inline bytecode built with JVM target 11 into bytecode that is being built with JVM target 1.8. Please specify proper '-jvm-target' option.

It seems that koinViewModel is built using Java 11 while I am targeting my android setup to 1.8 as below

kotlin {
    androidTarget {
        @OptIn(ExperimentalKotlinGradlePluginApi::class)
        compilerOptions {
            jvmTarget.set(JvmTarget.JVM_1_8)
        }
    }
}

android {
    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }
}

Is there something that I am missing? Or is koin-compose-viewmodel is not meant to use with jvm 1.8?

what version do you use?

[Atul Gupta]

koin-bom = "4.0.0-RC2"

[arnaud.giuliani]

compose needs java 11 I think

[Atul Gupta]

But android is for java 1.8 right?
So everywhere it gets mentioned to use below config

compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }

[arnaud.giuliani]

it depends.

[Atul Gupta]

compose needs java 11 I think is there any doc for this? I think I am getting it wrong

[arnaud.giuliani]

I'm still checking

[Atul Gupta]

You JDK to build the project can run on any java version(> 13) but your bytecode that actually runs on device should target VERSION_1_8 o/w common code which is compiled with later version of Java will not be able to run on Android

[arnaud.giuliani]

yeah, there is glitch in the gradle config. Just checking if this is a constraint or an issue

[arnaud.giuliani]

ok, got some VERSION_11 traces around. Removed it 👍

[arnaud.giuliani]

thanks for the feedback

[Atul Gupta]

Actually it should be explicit VERSION_1_8 o/w I think it fallbacks to you installed jdk version which is running the Gradle(or do you have some other way to set it?)

[arnaud.giuliani]

I need to specify it everywhere

[arnaud.giuliani]

on the library side, ensuring we keep everything java8

[Atul Gupta]

I think yes..

[arnaud.giuliani]

it' has been updated 👍

[Atul Gupta]

Also update means new release has been published or PR has been merged?

[arnaud.giuliani]

yes
