Hey folks, after upgrading my multiplatform project to kotlin 1.3.20 and ktor 1.1.2 I am running into this exception when running my tests under common/androidTest. The problem just occurs when running the tests.

I am running into a

java.lang.NoClassDefFoundError: kotlinx/serialization/json/Json

when executing tests in a multiplatform project. Any help would be much appreciated 🙏

what is the point / use of the

metadata

artifact? I was trying to add

com.soywiz:klock

to my multiplatform project, and I was struggling because I couldn't find a recent version for which all artifacts are present in the maven repository. I cloned its source and installed it to my local maven repository. The

klock

artifact is not present, but I tried adding

klock-metadata

as a dependency. It worked in one subproject, although I didn't try compiling, but not in another. @Deactivated User

Could we hope for annotation processing one day in non-jvm projects? Is that too far fetched?

Hi, guys cant build project for ios after plugin update from 1.3.0 to 1.3.21 error: Compiler version info: Konan: 1.1.2 / Kotlin: 1.3.21 tried to put konan as dependency into gradle, does not worked for me

Hi, I have one Java file that can't be converted to Kotlin due to Kotlin limitation (hiding a java field in a subclass by using the same name), and I'd like to migrate the library having this class to the Kotlin multiplatform plugin (even though I would just publish for Android for that module). Is there a way to add java compilation for this file so it's included in the final aar?

Hi folks, can’t seem to find any documentation on publishing a “common” artifact via the kotlin-multiplatform plugin. Are there any example projects doing so?

Is there a uniform jvm/js/native Date library in the works as part of libstd?

Are there any mpp mocking libraries out there yet?

Is there an example how to access android sdk from androidMain sources in MPP? I have applied

com.android.library

plugin, but during compilation I still get

Unresolved reference: android

when trying to access classes from android sdk. Do I miss something here? https://github.com/MattSkala/kotlin-examples/commit/22477f5b24badb23d158f1dd3760ee2780d01a9a

Hey guys, Just updated the 'kotlin-multiplatform' plugin from 1.3.10 and 1.3.21.. Also updated the compilations.main.outputkinds to new binaries block.. And noticed the generated iOS target framework size has increased.. Previously it was Debug Framework = 4.3MB Release Framework = 2.8MB After update Debug Framework = 4.8MB Release Framework = 7.1MB Debug version contains (Arm32, Arm64, x64) Release version contains (Arm32, Arm64) Also now release framework size is greater than the Debug version. Why is this happening. Am I doing something wrong..

Hey folks I am totally new to this stuff and am banging my head against an issue. in my

jvmMain

project I keep getting a unresolved reference to ktor's

HttpClient

class that exists in

commonMain

.

How do you create an iOS Framework with multiple architectures?

I’m trying to publish my mpp lib to my local maven repo and I get

> Task :generateMetadataFileForAndroidReleasePublication FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':generateMetadataFileForAndroidReleasePublication'.

Wow. Getting tests to run for a JS target in a multiplatform project is difficult: it’s not documented, and there are no examples in the kotlin-examples repo, and Gradle is opaque even with a Kotlin build script. Anyone got a small example of a multiplatform project that runs the tests for both the JVM and JS platforms?

Getting this error when I simply add a mingwX64 target without any configuration to my multiplatform project on version 1.3.21, gradle 4.7:

kotlin.UninitializedPropertyAccessException: lateinit property compilation has not been initialized

fun cinterops(action: NamedDomainObjectContainer<DefaultCInteropSettings>.() -> Unit) = cinterops.action()
fun cinterops(action: Action<NamedDomainObjectContainer<DefaultCInteropSettings>>) = action.execute(cinterops)

These functions of

KotlinNativeCompilation

are identical and I can’t call any of them because both match anything I write, any idea?

Is there a built in way to convert a

Throwable

into a

NSError

or

NSException

?

How do I change the sourceSet of a target without losing IDE support?

Will we be able to use

actual inline class

to define

expect class

in the future? This to me seems like a prime use case of inline classes, as type aliases are not an option if there are tiny differences between the expected and actual type. I previously assumed that this is already possible, but it isn't, and I don't see a reason why it shouldn't be other than a bit of implementation complexity.

Any ideas? ☝️

This does not seem to work.

private val httpClient: HttpClient = HttpClient {
        install(JsonFeature) {
            serializer = KotlinxSerializer().apply {
                setMapper(GloUserDTO::class, GloUserDTO.serializer())
            }
        }
    }

It produces:

Error:(15, 57) Kotlin: [net.publicmethod.multi_glo_sdk.jvmMain] Unresolved reference: serializer

Are native Kotlin platforms supported in IntelliJ? When I try to debug failing tests on the native platform, IntelliJ runs them via Gradle and then debugs Gradle itself, not the native code it’s running. Do I need to install CLion to work on Kotlin Native at the moment?

What is the limit of what you can do with reflection in kotlin MPP? Can you do something simple like

this::class.simpleName

? Is there a list of things part of

stdlib

?

Hi, I tried to add languageSettings to android sourceSets for an experimental annotation, unccessfully, following the example there: https://kotlinlang.org/docs/reference/building-mpp-with-gradle.html#language-settings I tried the following:

kotlin {
    sourceSets {
        filter { it.name.startsWith("android") }.forEach {
            it.languageSettings.apply {
                useExperimentalAnnotation("kotlin.Experimental")
            }
        }
    }
}

but I'm getting an error because the test sourceSets defined by the Android Gradle plugin (version 3.3.1) don't have the experimental annotation. How can I solve that issue to enable this experimental annotation in my android source sets defined my Kotlin multiplatform gradle plugin? The exact error message is the following:

Inconsistent settings for Kotlin source sets: 'androidDebugAndroidTest' depends on 'androidAndroidTest'
'androidDebugAndroidTest': set of experimental annotations in use is []
'androidAndroidTest': set of experimental annotations in use is [kotlin.Experimental]
The dependent source set must use all experimental annotations that its dependency uses.

Is there a multiplatform function to get the time?

And also an

interval

function that isn’t as terrible as this one I just wrote:

Does anyone have an example of working bintray deploy gradle configuration for an mpp project?

@h0tk3y Hey, do you by any chance know if there is a way to do a

includeBuild

dependency substition on a preset of an mpp project? In a non-mpp android module I have a dependency

mpp-module-android

, and trying to substitute it with

mpp-module

, but it fails with

Unable to find module with Gradle path

Is there document that outlines which language features are supported on different platforms? E.g. I’ve got a multiplatform project, and the tests are failing on native platforms for code that uses reified generics. Are they implemented on native? Will they be?
