Hey everyone, best wishes!

I’m currently migrating to version 6.0.1 with Kotlin 1.8.0 (mandatory I would assume from the build errors it gave me?). Gradle sync works fine, but when I try to build the project I’m presented with following error:

PROJECTPATH/build/generated/ksp/metadata/commonMain/kotlin/be/sigmadelta/PROJECTNAME/service/UserService.kt:15:9 Cannot inline bytecode built with JVM target 17 into bytecode that is being built with JVM target 1.8. Please specify proper '-jvm-target' option

So then I change the jvmTarget to `17`as prompted (see below):

jvm("backend") {
        compilations.all {
            java {
                targetCompatibility = JavaVersion.VERSION_1_8
            }
            kotlinOptions {
                jvmTarget = "17"
                freeCompilerArgs = listOf("-Xjsr305=strict")
            }
...

Afterward I try to build again, but then it encounters a build error in `Main.kt`:

e: PROJECTPATH/src/backendMain/kotlin/be/sigmadelta/PROJECTNAME/Main.kt:56:5 None of the following functions can be called with the arguments supplied: 
public fun Application.kvisionInit(vararg modules: Module): Injector defined in io.kvision.remote
public fun Application.kvisionInit(initStaticResources: Boolean, vararg modules: Module): Injector defined in io.kvision.remote
public fun Application.kvisionInit(initStaticResources: Boolean, json: Json, vararg modules: Module): Injector defined in io.kvision.remote
public fun Application.kvisionInit(json: Json, vararg modules: Module): Injector defined in io.kvision.remote

And this happens on an unchanged kvisionInit which worked fine on version `5.18.1`:

fun Application.main() { 

...

kvisionInit(
        Json {
            prettyPrint = true
            isLenient = true
            classDiscriminator = "class"
        },
        KoinModules.tableModule,
        KoinModules.repoModule,
        KoinModules.serviceModule,
        KoinModules.appModule(
            this@main,
            JwtProps(
                secret = environment.config.property("jwt.secret").getString(),
                issuer = environment.config.property("jwt.issuer").getString(),
                audience = environment.config.property("jwt.audience").getString(),
                realm = environment.config.property("jwt.realm").getString()
            )
        )
    )
...

Does anyone know how to resolve this issue? I assume something is just going wrong with the mandatory Kotlin upgrade to 1.8.0

[Robert Jaros]

Have you changed JavaVersion.VERSION_1_8 to JavaVersion.VERSION_17 as well?

[Robert Jaros]

Do you run your build with JDK17?

[sigmadelta]

I just changed over the JavaVersion.VERSION_1_8 to JavaVersion.VERSION_17 , and the javaVersion mentioned in gradle.properties to 17 as well; but it makes no difference currently.

My project is also configured to use the Zulu JDK 17, tried switching over to the Jetbrains JDK 17 but that also doesn’t make a difference currently

[Robert Jaros]

have you tried running gradlew from command line?

[sigmadelta]

Yes, ./gradlew clean assemble results in the same build errors as in the IDE so I assume it’s not IntelliJ related

[Robert Jaros]

Can you share your project?

[sigmadelta]

Sure, I can invite you through Github

[Robert Jaros]

You need to upgrade Koin to 3.3.0

[Robert Jaros]

It resolves the problem with kvisionInit

[Robert Jaros]

There are some other compilation issues after that

[Robert Jaros]

but in the frontend module and they are expected

[sigmadelta]

Seems to fix the backend part already indeed, thanks! 👍

[Robert Jaros]

one is the routing and the other is probably onClick return value

[Robert Jaros]

both are described in the migration guide

[sigmadelta]

As for the front end, I’ve removed the bootstrap modules mentioned but I’ll have to look into deprecation of the add( methods and such

[sigmadelta]

Thanks for the help!

[Robert Jaros]

the add method is not deprecated

[Robert Jaros]

you just need to add a button and not button.onClick() {} result value

[Robert Jaros]

(which is not a button anymore)

[sigmadelta]

Super, all resolved now and project works again. Thanks!

[Robert Jaros]

Glad I could help :)

[sigmadelta]

So for reference to anyone encountering the same/similar issues:
General:
• Upgrade to Kotlin 1.8.0
• Upgrade Koin to 3.3.0
Frontend:
• Run ./gradlew kotlinUpgradeYarnLock if required by IntelliJ
• Follow migrationguide details
