Can't import dependencies for Kotlin multi platform common - kotlin

Question

I am trying out Kotlin multi-platform and trying to setup all my dependencies for it. Starting with commonMain
I am trying to add Koin and Ktor dependencies to the common portion but I cant seem to be able to use any of them.
This is my Gradle script
plugins {
id 'org.jetbrains.kotlin.multiplatform' version '1.3.61'
}
repositories {
google()
jcenter()
mavenCentral()
}
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android-extensions'
android {
compileSdkVersion 29
defaultConfig {
applicationId 'org.jetbrains.kotlin.mpp_app_android'
minSdkVersion 15
targetSdkVersion 29
versionCode 1
versionName '1.0'
testInstrumentationRunner 'android.support.test.runner.AndroidJUnitRunner'
}
buildTypes {
release {
minifyEnabled false
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'org.koin:koin-android:2.0.1'
implementation 'org.koin:koin-androidx-viewmodel:2.0.1'
implementation 'androidx.lifecycle:lifecycle-viewmodel:2.1.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.0-beta4'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
}
kotlin {
android("android")
// This is for iPhone emulator
// Switch here to iosArm64 (or iosArm32) to build library for iPhone device
iosX64("ios") {
binaries {
framework()
}
}
sourceSets {
commonMain {
dependencies {
implementation kotlin('stdlib-common')
implementation 'org.koin:koin-ktor:2.0.1'
implementation 'org.koin:koin-core:2.0.1'
// HTTP
implementation "io.ktor:ktor-client-core:1.2.6"
implementation "io.ktor:ktor-client-json:1.2.6"
implementation "io.ktor:ktor-client-serialization:1.2.6"
// Coroutines
implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core-common:1.2.1"
}
}
commonTest {
dependencies {
implementation kotlin('test-common')
implementation kotlin('test-annotations-common')
}
}
androidMain {
dependencies {
implementation kotlin('stdlib')
}
}
androidTest {
dependencies {
implementation kotlin('test')
implementation kotlin('test-junit')
}
}
iosMain {
}
iosTest {
}
}
}
// This task attaches native framework built from ios module to Xcode project
// (see iosApp directory). Don't run this task directly,
// Xcode runs this task itself during its build process.
// Before opening the project from iosApp directory in Xcode,
// make sure all Gradle infrastructure exists (gradle.wrapper, gradlew).
task copyFramework {
def buildType = project.findProperty('kotlin.build.type') ?: 'DEBUG'
def target = project.findProperty('kotlin.target') ?: 'ios'
dependsOn kotlin.targets."$target".binaries.getFramework(buildType).linkTask
doLast {
def srcFile = kotlin.targets."$target".binaries.getFramework(buildType).outputFile
def targetDir = getProperty('configuration.build.dir')
copy {
from srcFile.parent
into targetDir
include 'app.framework/**'
include 'app.framework.dSYM'
}
}
}
In the Sample.kt file that was generated when I created the project I tried to setup Koin in the main method
fun main() {
startKoin {
// declare modules
modules(myModule)
}
println(hello())
}
but startKoin cannot be resolved.
I cleaned/rebuilt the project, did a gradle sync and still cant import koin or any other dependency so what am I missing

Answer 1

Koin is not multiplatform capable. We have [multiplatform forks][1], but would need to chat about which to use and what version. We're still discussing multiplatform strategy.
Ktor's dependencies are more complex than that. See below. I removed your other dependencies for clarity, but you should leave them obviously :)
sourceSets {
commonMain {
dependencies {
implementation "io.ktor:ktor-client-core:1.2.6"
implementation "io.ktor:ktor-client-json:1.2.6"
implementation "io.ktor:ktor-client-serialization:1.2.6"
}
}
androidMain {
dependencies {
implementation "io.ktor:ktor-client-core-jvm:1.2.6"
implementation "io.ktor:ktor-client-json-jvm:1.2.6"
implementation "io.ktor:ktor-client-serialization-jvm:1.2.6"
}
}
iosMain {
dependencies {
implementation "io.ktor:ktor-client-ios:1.2.6"
implementation "io.ktor:ktor-client-core-native:1.2.6"
implementation "io.ktor:ktor-client-json-native:1.2.6"
implementation "io.ktor:ktor-client-serialization-native:1.2.6"
}
}
}
