I am having Gradle problems. I can not add serialization in a sub-project, without getting the error:

Caused by: java.lang.IllegalStateException: The Kotlin Gradle plugin was loaded multiple times in different subprojects, which is not supported and may break the build.

. This is my `settings.gradle.kts`:

pluginManagement {
    plugins {
        kotlin("multiplatform") version "1.6.21" apply false
        kotlin("js") version "1.6.21" apply false
        kotlin("plugin.serialization") version "1.6.21" apply false
    }
}

rootProject.name = "scribbles"
include("dom")
include("vdom")
include("web-workers")

include("examples:dom-demo")
include("examples:vdom-demo")

And this is my

web-workers

gradle:

plugins {
    kotlin("multiplatform")
    kotlin("plugin.serialization") // <- when commenting out this line it works again
}

repositories {
    mavenCentral()
}

kotlin {
    /** targets **/
}

Here is the repository: https://github.com/avwie/scribbles/tree/e1629ff6d3e4a322c590d92ba00b740b8f1cf6e6 Am I doing something wrong?

Hey Guys, I am using sealed class to handle api response. I am trying some code but getting some error. Can somone suggest me? Please see in the thread.

Hello again, I’ve a project with androidApp, iosApp, desktopApp (compose) and shared. All can access to com.repo.domain classes and shared code, except desktopApp:

dependencies {
    implementation(project(":shared"))
    implementation(compose.desktop.currentOs)
}

it gives me an error: “Packages cannot be imported” when I try to import a class. 🤷 IDE suggestion:

Add dependency on module 'App.shared.commonMain'

Any idea?

I just updated all of my KMM libraries and suddenly I’m getting this error only when building from iOS/Kotlin Native:

> Task :shared:linkPodDebugFrameworkIosX64 FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':shared:linkPodDebugFrameworkIosX64'.
> No extensions handle the extension type: kotlinx.metadata.klib.KlibModuleFragmentExtensionVisitor

Any ideas?

I am working on my KMM backend server and I got this error:

The 'java' plugin has been applied, but it is not compatible with the Android plugins.

In my shared build.gradle I have this. If I just use jvm() instead no issues, except it goes to androidMain not jvmMain.

kotlin {
    android()
    jvm {
        withJava()
    }

I have a sinking feeling it won't be resolved any time soon based on this issue: https://youtrack.jetbrains.com/issue/KT-30878 Is the best bet to just have web and server have one KMM project and android/iOS and everything else have the other, or should servers just not be in the KMM project currently?

I just published uri-kmp a uri library for all kmp targets, ported from AOSP's

Uri

implementation. Check it out, I'd love to hear your feedback 😄

Is there any way to disable

explicitApi

for test source sets? (edit: looks like it's only an issue for

androidTest

)

Good morning, Where do I see the

shared

framework from a KMM project in Xcode? It's neither listed under the

Frameworks

folder neither nor

Embedded Frameworks

in Xcode.

hello! How do you share the iOS CocoaPods Pods? I use Artifactory for Android/Java (with maven-publish), so it would be convenient to upload them there as well. I am using cocoapods plugin saw about CocoaPods repositories and cocoapods-art but I cannot find if the setup would require to publish then separate or together for a multiplatform library.

Hi, I am trying to bundle

moment.js

into my jar and this is what I have tried. https://github.com/overfullstack/revoman-root/blob/master/src/jsMain/kotlin/Main.kt But the final bundle generated doesn’t have the moment functions as expected. Am I doing it right?

I started a KMM project in fall and now it would be time for another one. In my previous project I did not use the new MM, nor have to worry about M1 issues. However, going into the new project I would like to support M1 and perhaps also use the new MM. With those constraints in mind, are there currently any known pitfalls when it comes to M1 and KMM?

And would a Stop the world pause break the swift UI necessarily?

I saw that Jetbrains seems to have closed offices in Russia following the war, and I’m wondering if this might have put work on KMM on hold.

I simply moved my

data

layer classes along with the dependencies (sqldelight) from

:shared

to a new Multiplatform module

:data

. But since then, iOS doesn’t build with the following error :

Undefined symbols for architecture arm64:
  "_sqlite3_column_type", referenced from:
      _co_touchlab_sqliter_sqlite3_sqlite3_column_type_wrapper108 in result.o
  "_sqlite3_bind_parameter_index", referenced from:
      _co_touchlab_sqliter_sqlite3_sqlite3_bind_parameter_index_wrapper84 in result.o
...

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':shared:linkDebugFrameworkIosArm64'.
> Compilation finished with errors

shared/build.gradle.kts

looked like this before creating

:data

module.

val commonMain by getting {
            dependencies {
                implementation("com.squareup.sqldelight:runtime:$sqldelight")
                implementation("com.squareup.sqldelight:coroutines-extensions:$sqldelight")
            }
        }

        val androidMain by getting {
            dependencies {
                implementation("com.squareup.sqldelight:android-driver:$sqldelight")
            }
        }

        val iosMain by creating {
            dependencies {
                implementation("com.squareup.sqldelight:native-driver:$sqldelight")
            }
            dependsOn(commonMain)
            iosX64Main.dependsOn(this)
            ..
        }

After creating

:data

and moving these dependencies to

data/build.gradle.kts

, I just added this in

shared/build.gradle.kts

val commonMain by getting {
            dependencies {
                implementation(project(":data"))
            }
        }

I haven’t changed anything else. Am I missing out on anything here ? 🤔

I have a big JVM/Android/iOS multiplatform project with dozens of libs as modules. Let’s say I have a backend developer who wants to make changes to some modules and try these changes locally in their project. Is there an easy way to publish all artifacts for one platform in a multi-modules project or do I need to create custom tasks? Anyone made such tasks? I myself am using

publishToMavenLocal

a lot while working (for example) only on iOS and only in the simulator, so I would benefit from this kind of feature

Can I consume multiple dynamic Kotlin/Native frameworks in a single iOS application?

Hey guys, Do you have any good example of Kotlin: Sealed Classes for better handling of API Response in multiplatform?

Hi guys, how can I use

String.format

function in web application? I saw that String in webapplication comes from kotlin-stdlib-js package, and it doesn’t have format function?

Hey guys what is the difference between of runblocking and suspend function in KMM ?

Hello, I'm trying to do mocking in a multiplatform project (jvm, native, common), what is a framework that works well for you guys and if possible works well with kotest. I'm trying out

org.kodein.mock.mockmp

, tests and mocking works but building the project fails

The provided plugin com.google.devtools.ksp.KotlinSymbolProcessingComponentRegistrar is not compatible with this version of compiler

so I'm not sure if it's the best framework for now. Any thoughts?

I am looking for an example sample repo which is just the KMM template with just web added. Does not need to be a complicated example just can do the same thing as the KMM template but has web. I have found tons of examples out there where the gradle files look very different so its hard to translate. I would like to stay as close to KMM as possible gradle structure.

does anyone know how to make this https://discuss.kotlinlang.org/t/feature-request-typealias-for-expected-types/20054 work? any other ideas?

[SQLDelight, iOS] Hi, my SQLDElight database persists even when I delete and reinstall the app... Does anyone know how to fix this?

Hi everyone, I migrate to Kotlin 1.6.10 and after when compile iOS project by Xcode get error. But! An error occurs only in release build for iOS, if build into device or simulator - no problem * Compiler version info: Konan: 1.6.10 / Kotlin: 1.6.10 * Output kind: FRAMEWORK e: java.lang.NullPointerException at org.jetbrains.kotlin.backend.konan.optimizations.DataFlowIR$SymbolTable.mapClassReferenceType(DataFlowIR.kt:520) at org.jetbrains.kotlin.backend.konan.optimizations.DataFlowIR$SymbolTable.mapType(DataFlowIR.kt:554) at My gradle configure:

com.android.tools.build:gradle:7.1.2
org.jetbrains.kotlin:kotlin-serialization:1.6.10
org.jetbrains.kotlinx:kotlinx-datetime:0.3.2
org.jetbrains.kotlinx:kotlinx-serialization-core:1.3.2

What could be the reason?

Imagine someone (me) wants to create an opensource kotlin multiplatform crypto library with support for JVM, JS(nodejs and browser), Darwin and all other native targets What will you need from it: 1. Hashing - base64, sha*, md5, other 2. encryption: AES, DES, RSA, DH, Salsa20, other 3. TLS 4. key management system (like jvm key managers) 5. certificates - pem, asn.1(der), pkcs12, other 6. PBKDF2WithHmacSHA512 , HmacSHA256 and other unreadablewords 7. something else? For what, do you need to use it and how? Using plain

ByteArray

s or `String`s or via some lower level IO streams (like jvm InputStream/OutputStream or multiplatform ones like okio)? What else should I know to make you happy? 🙂

Hi everyone! Ii have a KMP project and I’m trying to get it to assemble an XCFramework for ios. I thought I had everything setup right, but when I run the

assembleXCFramework

task, I get an error:

the path does not point to a valid framework: /Users/my.user/dev/wager-utils/build/fat-framework/debug/wager_utils/iosSimulator/wager_utils.framework

And in looking in the build folder, indeed that path is not correct. Specifically there is no

wager_utils

folder. Instead the folder is

wager-utils

(dash instead of underscore … see screenshot below). Any idea how that path gets generated, or how I can control it to fix this issue?

Heyo! I've got a KMP project an am using value classes, but cannot for the life of me figure out how to require their use in Java from an interface method.

sealed interface Key {
    fun descriptor(address: Address): String
}

@JvmInline
value class Address(@JvmField val value: String)

Calling From Java:

public class SomeClass {
    public void someFunction(Key key) {
        // Key.descriptor accepts a String, not an Address
        String descriptor = key.descriptor("");

        Address address = new Address("someaddress");

        // key.descriptor does not accept an Address and IDE shows error
        String descriptor2 = key.descriptor(address);
    }
}

Any Ideas?

Hi friends! Does anyone know of a MPP library for process execution (similar in behavior to

ProcessBuilder

or

Runtime.exec

in the Java ecosystem)? Any suggestion is welcome! Thanks! Have a great weekend!

Hi, guys. Have one question about plans for multiplatform. Are there any plans to make kmm more full featured like flutter/react native. Searched through roadmaps and comments, but haven’t found anything meaningful. So that three or more years ago it was said that there are no plans for common ui, buy now we have compose multiplatform, so question comes back) thanks
