what’s the correct way to point

JavaExec

task’s

classpath

to the JVM variant of a multiplatform library? here’s an example:

configurations {
  cli
}
dependencies {
  cli "com.example:a-multiplatform-library:1.0"
}
tasks.register("myTask", JavaExec) {
  classpath = configurations.cli
  main = "com.example.Main"
}

right now running

myTask

fails with the following output:

What is IntelliJ trying to tell me? 😄 Why is it trying to build iOS code anyway - IntelliJ doesn't support that and Gradle delegation is disabled 🤔

Anybody have a link to an MPP project that includes Android/JVM unit tests such that there are no deprecation warnings (‘AndroidJUnit4’ is deprecated. Deprecated in Java) AND can handle calling suspend/coroutine methods (Module with the Main dispatcher had failed to initialize. For tests Dispatchers.setMain from kotlinx-coroutines-test module can be used)?

Hi All… I am new to Kotlin Multiplatform/Android(I am a iOS dev). Apologise for asking basic questions: I am following steps provided provided in https://kotlinlang.org/docs/tutorials/native/mpp-ios-android.html#creating-ios-application tried creating as a project and also tried by adding as a module.

I’m able to compile the project, but now when I try to run it I get this error on the browser console log:

Uncaught Error: Error loading module ‘app’. Its dependency ‘ktor-client-core’ was not found. Please, check whether ‘ktor-client-core’ is loaded prior to ‘app’.

is there any way to still get a class name without reflection? Just using it for logging purposes in order to get more context

before 1.3.40

this::class.simpleName.toString()

worked and now it crashes because it requires 'kotlin-reflect.jar'

and AFAIK reflection isn't multiplatform

Pretty sure

simpleName

ought to be there on both jvm and js. Not sure about native: http://tiny.cc/nr4j8y

I'm trying to add new compilation for android like this:

android {
        // android block filled with defaultConfig, buildTypes and sourceSets settings
}

targets {
        fromPreset(presets.android, 'android')
}

targets['android'].compilations.create('sm_name')

But I keep getting an error:

Cause: lateinit property androidVariant has not been initialized

Any ideas on what might be causing it?

So if I have a mpp targeting ios, android and js, and a lot of stuff are the same except for the fact that on js there's no persistance (with sqldelight for example)... How should I setup the project? I was thinking about

libCommon

which has all the models and business logic for the 3 platforms,

libMobile

which adds the persistance only for android/ios and then the

app

module with the code specific for every platform. The js app will have

project(':libCommon')

, while the android/ios apps will have

project(':libMobile')

, and libMobile will have

project(':libCommon')

. Is there any better approach? Thanks everyone 🙏 (ps: I'm not even sure this will work, that's just what I'm thinking about before beginning a simple project)

Can anyone debug inline functions in common code? I filed a bug around it, but I'm wondering if it's just my specific situation, or if it's across the board: https://youtrack.jetbrains.com/issue/KT-32160

does anybody know how to add scala into a kotlin multilib project (resembling the intellij default multilib webapp)? If there have to be linear dependencies, I'd want scalaMain to be able to call functions in commonMain, and jvmMain to be able to call functions in scalaMain

I tried including it with

implementation project(path: ":multiplatform-project", configuration: "jvmDefault")

, but it appears that dependency resolution breaks when I try to add both projects into same gradle project

Does anyone have a workaround for the `java`/`android` plugin clash in K/MP?

Is there a succinct way to create targets from all native presets and add a dependency (native coroutines core)?

I really don’t like all the boilerplate required to setup the js test runner.

Is it possible to have expect declarations in a multiplatform library and provide the actual implementations in the project importing that library?

no. that's usually called an interface.

Oh, sarcastic. 😁 Thanks Jake. Just wondered if I was missing something… So, if an interface is the only way around that, what’s the best way to provide an implementation that the library can access when it needs it, without having to pass it through as a parameter.

Ideally I’d provide some kind of service locator or DI construct, but I’m not quite sure how to do that.

Some new interesting multiplatform (iOS+Android) stuff https://suparngp.github.io/kotlin-multiplatform-projects/, is suparngp here in slack?

Hello everyone. I'm now trying to compile the multiplatform library I created to a single jar to later be added to android projects. The problem I have is the original build has only the classes I created so depencies of ktor for example are not included. To solve this I used shadow jar but that compiled kotlins runtime with it so I had a lot of errors of duplicate classes. Any ideas on what to do? My task that is creating the uber jar: Problem I keep having in the android project

I guess the issue here is the lack of code in

commonMain

, hence there’s no

main/wire-tests.klib

artifact, is there any way to configure the MPP to ignore this?

Hello 🙂 I am trying to understand multiplatform projects and setting up one of them. The project is composed of a backend using Spring and a front using react. I with to use the common to for serialisation and sharing few resources. From what I got, it’s the purpose of multiplatform projects, right? Or is it intended for projects that would share more code together and my project would better be split in two independant parts?
