kotlin - 创建 jvm 和 Kotlin 多平台的 Github 库组合

Question

我正在尝试构建一个 Android 库，我有以下内容:

图书馆的 Github Repo

库 1:可编译为 Android 和 iOS 的 Kotlin 原生/多平台代码

库 2:Kotlin/JVM 代码依赖于库 1

示例应用程序:使用库 2 和库 1 的应用程序

个人安卓项目

依赖上面的Github库

在我的个人项目中，我只有:

implementation 'com.github.username:myrepo:0.5'

问题

私有(private) Android 项目正在加载 android 库(库 2)，但无法访问多平台 kotlin 模型和函数(库 1)。

请注意，该库的示例应用程序运行良好。我怀疑 jitpack.io 没有正确发布工件。关于如何解决这个问题的任何想法？应该对 gradle 文件做些什么来解决问题？

我想单独发布多平台库。我试图从多平台 Kotlin 模块访问它，但我得到“无法解决依赖关系”。这就是我正在尝试的:
implementation 'com.github.username.myrepo:library1_moduleName:0.1'

Gradle for Library 1 多平台:

plugins {
    kotlin("multiplatform")
}

kotlin {
    //select iOS target platform depending on the Xcode environment variables
    val iOSTarget: (String, KotlinNativeTarget.() -> Unit) -> KotlinNativeTarget =
        if (System.getenv("SDK_NAME")?.startsWith("iphoneos") == true)
            ::iosArm64
        else
            ::iosX64

    iOSTarget("ios") {
        binaries {
            framework {
                baseName = "library1"
                freeCompilerArgs.add("-Xobjc-generics")

            }
        }
    }

    jvm("android")

    sourceSets["commonMain"].dependencies {
        implementation("org.jetbrains.kotlin:kotlin-stdlib-common")
    }

    sourceSets["androidMain"].dependencies {
        implementation("org.jetbrains.kotlin:kotlin-stdlib")
    }
}

val packForXcode by tasks.creating(Sync::class) {
    val targetDir = File(buildDir, "xcode-frameworks")

    /// selecting the right configuration for the iOS
    /// framework depending on the environment
    /// variables set by Xcode build
    val mode = System.getenv("CONFIGURATION") ?: "DEBUG"
    val framework = kotlin.targets
        .getByName<KotlinNativeTarget>("ios")
        .binaries.getFramework(mode)
    inputs.property("mode", mode)
    dependsOn(framework.linkTask)

    from({ framework.outputDirectory })
    into(targetDir)

    /// generate a helpful ./gradlew wrapper with embedded Java path
    doLast {
        val gradlew = File(targetDir, "gradlew")
        gradlew.writeText(
            "#!/bin/bash\n"
                    + "export 'JAVA_HOME=${System.getProperty("java.home")}'\n"
                    + "cd '${rootProject.rootDir}'\n"
                    + "./gradlew \$@\n"
        )
        gradlew.setExecutable(true)
    }
}

tasks.getByName("build").dependsOn(packForXcode)

库 2 的 Gradle

apply plugin: 'com.android.library'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {

    repositories {
        google()
        jcenter()
        maven { url 'https://jitpack.io' }
    }

    compileSdkVersion 29
    buildToolsVersion "29.0.0"


    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 29

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        consumerProguardFiles 'consumer-rules.pro'
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    api project(":library1")
}

我建议你改变你的build.gradle针对 android/的配置将其更改为

plugins {
    kotlin("multiplatform")
    id("com.android.library")
    id("maven-publish")
}

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.0"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 29
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

kotlin {
    //select iOS target platform depending on the Xcode environment variables
    val iOSTarget: (String, KotlinNativeTarget.() -> Unit) -> KotlinNativeTarget =
        if (System.getenv("SDK_NAME")?.startsWith("iphoneos") == true)
            ::iosArm64
        else
            ::iosX64

    iOSTarget("ios") {
        binaries {
            framework {
                baseName = "library1"
                freeCompilerArgs.add("-Xobjc-generics")

            }
        }
    }

    // jvm("android")
    android {
        publishLibraryVariants("release")
    }

    sourceSets["commonMain"].dependencies {
        implementation("org.jetbrains.kotlin:kotlin-stdlib-common")
    }

    sourceSets["androidMain"].dependencies {
        implementation("org.jetbrains.kotlin:kotlin-stdlib")
    }
}

val packForXcode by tasks.creating(Sync::class) {
    val targetDir = File(buildDir, "xcode-frameworks")

    /// selecting the right configuration for the iOS
    /// framework depending on the environment
    /// variables set by Xcode build
    val mode = System.getenv("CONFIGURATION") ?: "DEBUG"
    val framework = kotlin.targets
        .getByName<KotlinNativeTarget>("ios")
        .binaries.getFramework(mode)
    inputs.property("mode", mode)
    dependsOn(framework.linkTask)

    from({ framework.outputDirectory })
    into(targetDir)

    /// generate a helpful ./gradlew wrapper with embedded Java path
    doLast {
        val gradlew = File(targetDir, "gradlew")
        gradlew.writeText(
            "#!/bin/bash\n"
                    + "export 'JAVA_HOME=${System.getProperty("java.home")}'\n"
                    + "cd '${rootProject.rootDir}'\n"
                    + "./gradlew \$@\n"
        )
        gradlew.setExecutable(true)
    }
}

tasks.getByName("build").dependsOn(packForXcode)

创建 AndroidManifest.xml src/main/AndroidManifest.xml 下 library1 的文件

<manifest package="library1"/>

你现在可以将你的项目推送到 github，创建一个标签并等待 jitpack 发挥它的魔力

当你想在 library2 中使用它时，在 dependencies 下部分，只需添加

implementation 'com.github.username.myrepo:library1-android:0.1' //for android
