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

Have you changed

JavaVersion.VERSION_1_8

to

JavaVersion.VERSION_17

as well?

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

have you tried running gradlew from command line?

Yes,

./gradlew clean assemble

results in the same build errors as in the IDE so I assume it’s not IntelliJ related

Can you share your project?

Sure, I can invite you through Github

You need to upgrade Koin to 3.3.0

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

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

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

the add method is not deprecated

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

Glad I could help :)

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
