无法导入 Kotlin 多平台通用的依赖项

Posted 2023-04-15

【中文标题】无法导入 Kotlin 多平台通用的依赖项

【英文标题】：Can't import dependencies for Kotlin multi platform common

【发布时间】：2020-04-30 18:20:02

【问题描述】：

我正在尝试 Kotlin 多平台并尝试为其设置所有依赖项。以commonMain开头

我正在尝试将 Koin 和 Ktor 依赖项添加到公共部分，但我似乎无法使用它们中的任何一个。

这是我的 Gradle 脚本

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'
        
    

在我创建项目时生成的Sample.kt 文件中，我尝试在main 方法中设置Koin

fun main() 
    startKoin 
        // declare modules
        modules(myModule)
    
    println(hello())

但startKoin 无法解析。

我清理/重建了项目，进行了 gradle 同步，但仍然无法导入 koin 或任何其他依赖项，所以我错过了什么

【参考方案1】：

Koin 不支持多平台。我们有 [multiplatform forks][1]，但需要讨论使用哪个以及哪个版本。我们仍在讨论多平台战略。

Ktor 的依赖比这更复杂。见下文。为了清楚起见，我删除了你的其他依赖项，但你应该清楚地离开它们:)

【讨论】：

我要关闭这个存储库，它列出了与多平台 github.com/AAkira/Kotlin-Multiplatform-Libraries 一起使用的库。所以只关心Android和iOS，为了能够做共同的事情，我应该寻找具有平台原生标签的库？

我快速浏览了一下，只是我发布的库完全被错误分类。我不会去那个列表。

官方 alpha 为 3.0。添加 repo dl.bintray.com/ekito/koin 和依赖项“org.koin:koin-core:3.0.0-alpha-1”。我们将在接下来的几天内将其添加到 KaMP Kit：github.com/touchlab/KaMPKit
