Is there a good sample to look at for JS and multiplatform? I have KotlinJS in multiplatform library code but have no idea how to actually run tests. Library seems to build fine and publish, but no tests ever run for the JS portion.

Anyone working on a multiplatform compile-time DI compiler plugin ? i.e. Dagger but multiplatform

Not as far as I know, but compiler plugin is something I wouldn’t invest in right now. Just because we will break API.

that specific use-case is on my radar and might be my pet project over the holidays. was thinking of using Android Lint's UAST infrastructure to do it at the source layer with source generation and a Gradle plugin to start with. It could be moved to a compiler plugin later.

This is not “compile-time” and many would argue about statement that “Koin is DI”

Hello guys! Here you can find another mpp project🙂 https://github.com/sergiocasero/votlin-app We use ktor for backend, react, android and ios for clients. It's more or less like kotlinconf app (the app is for voting talks for other event, here in Spain 🙂 ), but we use MVP (sharing presenters) and we're also sharing the Remote Data Source (currently serializing with serializationx because ktor-client-json feature is not available for all platforms yet). Thanks to @marcinmoskala and @wiyarmir repos, they are really really helpfull! The project is still WIP, suggestions, PRs and (why not) ragging are welcome!

Is it possible to use kapt on a mpp?

hey, has anyone able to get junit 5 to work with a multiplatform project? I am using JUnit5 on the JVM to run the tests, and i have

use gradle runner

selected in my IDEA preferences. Whenever I try to run the tests though, I get the [included] error. [stacktrace mode enabled] When i try running

gradle jvmTest

though, it succeeds without any problems.

Is it normal that I can't use cocoapods on iOS in a mpp? I tried some pods just for testing purpose but I always get

ld: framework not found _podname_

(I'm using the xcworkspace)

I've tried the config used for ios but I get errors about not finding actuals. However, they should be available. I don't have ndk hooked up anywhere, so maybe thinking the cause isn't what the error is saying.

How can I compile Kotlin-JavaScript to JavaScript files in a multiplatform project? There is only one gradle file

will there soon be an dokka update to support mpp?

Does Kotlin Multiplatform support native generic type parameters? Or are they stripped?

Hey friends, I'm trying out New MPP with 1.3.0 stable, and running into some weird issues when trying to run a test in the IDE. Whenever I try running a specific test (from my

commonTest

sources) using the Play button in the gutter, I get

Error:(1, 18) Kotlin: [my-module_jvmMain] Declaration annotated with '@OptionalExpectation' can only be used in common module sources

. Tests run perfectly fine with

./gradlew :my-module:jvmTest

though! I have a couple methods annotated with

JsName

and

JvmStatic

, but they very clearly are in the common module sources. I'm using a standard

fromPreset(presets.jvm, 'jvm')

target. Do I need to explicitly call

useExperimentalAnnotation

or

enableLanguageFeature

to use annotations marked as

@OptionalExpectation

? Or is this an IDE issue? If it's an IDE issue, is there a ticket I should be following?

Another multiplatform related bug/question: I've defined a file

utils/TimeUtils.kt

in my

commonMain

source set, with a top-level

expect fun getCurrentTime(): Long

declaration. I've also defined a file

TimeUtils.kt

in my

jvmMain

source set, in the same

utils

package, with an

actual fun getCurrentTime(): Long = System.currentTimeMillis()

. Attempting to build this project is giving me an error:

Duplicate JVM class name 'utils/TimeUtilsKt' generated from: package-fragment utils, package-fragment utils

Is this supposed to be allowed? Using

@file:JvmMultifileClass

doesn't fix the issue either... Do the files just have to be named differently altogether?

Are there any sample libraries publishing with the new plugin dsl and an Android aar? I have jvm and native publishing with gradle 4.7, and am able to publish with the older "platform" plugin, but not clear on how it would work with the newer dsl.

I guess the anwser is "Not yet". But just to be sure: Is there any way to do parametrized multiplatform tests ?

Does this mean the multiplatform project is closer to building out an Android and iOS app? Or are we still a ways to go?

Hi guys! Is there any tutorial/article explaining how to develop mpp libs?

Hi guys, just an architecture question, why is better to have only 1 module with all the targets?? In my opinion, is better to have 1 module per platform, no?

Hi all, I created a brand new MPP project in IDEA. My

jvmMain

modules uses logback for logging, which works fine. However, IDEA is not copying

src/jvmMain/resources/logback.xml

to the build folder, and so my config is not picked up at runtime. When I manually copy

logback.xml

to

build/classes/kotlin/jvm/main

before running my main method, the config is picked up by logback. Anyone have any idea where I should look for a solution? I haven't used Gradle before, so I have no idea if I need to configure something on that side?

src/jvmMain/resources/

is part of the classpath, so it seems more like an IDEA issue?

It seems that

sort

isn't necessarily always stable. Despite anecdotally being stable in JVM, its unstable in certain JS environments and the docs don't make any guarantees about stability. Does anyone know of a multiplatform-friendly way to do stable sorts? https://youtrack.jetbrains.com/issue/KT-12473

Hello. I just started a multiplatform project through IntelliJ's Kotlin(Mobile Android/iOS) project. I got it to compile and build on Android. However, I'm unable to access iOS specific domain information (such as UiDevice) in a kotlin file under the iosMain folder. Does anyone know what I have to do?

Hello, I am building a multiplatform library using Kotlin. The library should be usable by Kotlin user on the JVM (obviously), but also by Java developers. Because of this requirement, I need to setup a java unit test suite to be able to test how the library syntax will look like from Java. I am having troubling setting up a simple java test folder with a Junit dependency. My gradle file looks like this at the moment. Can someone point me towards the right direction ?

Hello! I'm trying to set up a multiplatform (Android and iOS) project. I'm able to write Kotlin multiplatform code for JVM and for iOS. Now I'm trying to get iOS utilize the Common project. According to the documentation I should link the xcode-frameworks with Xcode, however I cannot find it under my Common/build folder. Does someone know what do to?

@russhwolf the main problem of the new kotlin MPP is its lack of documentation. https://youtrack.jetbrains.com/issue/KT-27967

Any examples of publishing

aar

with mew mpp? Is it even possible?

Hey! I'm trying to access types and methods of the stdlib (specifically:

Sequence

) from Swift. It seems, that the generated framework headers only include definitions for my code but misses a lot from the stdlib. So there actually is the compiled

KotlinSequence

accessible but all the factory and extension functions are not -- which renders it pretty useless. Is there a way, to make some or all types and methods available in a compiled native xcode framework? Any hints are much appreciated!
