Hi friends, while using certain Compose Multiplatform libraries, I'm seeing this error in my IDE and I'm not sure how to fix this. Please help:

Here's the error message:

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

Also shown in the first image below

And over the internet, people have given suggestions to set androidTarget.compilations.all.kotlinOptions.jvmTarget = "11" and set android.compileOptions.sourceCompatibility and targetCompatibility to JavaVersion.VERSION_11

But I can see that's already done in my project (also shown in the second image below)

I have also tried invalidating the cache and restarting Android Studio.

Btw, I am using Android Studio Iguana | 2023.2.1 Canary 16, could that have anything to do with the issue? Or is there anything else I'm missing here?

[Pablichjenkov]

compileOptions {
        sourceCompatibility = JavaVersion.VERSION_17
        targetCompatibility = JavaVersion.VERSION_17
    }

Try like above. Could you identify the specific Library that when included triggers the issue?
If so try to update that library. Oh wait, I see the first screenshot, nvm.

Glad that you saw the library. Just to be clearer, I'm seeing this with 2 libraries:

1. io.github.qdsfdhvh:image-loader
2. moe.tlaster:precompose
Attaching error from 2nd library below:

I see in the library there are 2 functions named ImageRequest, one is an inline function and seems to be causing the problem. Can you try adapting your code to use the non inline version.
Also, I would open an issue in the compose-image-loader repo. Maybe someone dealt with it before.

Understood, many thanks!

Actually this is an IDE error but it seems to be fixed in the latest IntelliJ EA release.

Solution:

https://youtrack.jetbrains.com/issue/KTIJ-20816/Bogus-error-Cannot-inline-bytecode-built-with-JVM-target-11-into-bytecode-that-is-being-built-with-JVM-target-1.8

add @file:Suppress(“INLINE_FROM_HIGHER_PLATFORM”) to every affected file, and now your IDE is usable again!

This works well ✅ Thank you Michael
Btw, is there a way to use this globally for the whole project?

[Michael Paus]

Not that I know of.

Is there a reason the default target is a dinosaur version of JVM?

[Vishnu Shrikar]

also where do i put the @file thing, it just gives me a an error saying "expecting top level declaration"

[Shubham Singh]

@Vishnu Shrikar Put it on the top of your file
Before the package and imports declaration

[Vishnu Shrikar]

ok thank you that worked, turns out that Michaels slack message had the good looking but bad quotes on it 😛 I should have looked closer, for anyone who needs it.

@file:Suppress("INLINE_FROM_HIGHER_PLATFORM")

and thanks michael and shubham for the help
