Kotlin Multiplatform Cocoapods 集成问题

Question

所以我尝试使用 kotlin 多平台构建项目，我设法与数据库/ktor 等集成，但问题是当我需要一些来自 cocoapods 的依赖时。我已经看到从 kotlin 1.4 xcode 开始不需要构建这样的依赖项（但是即使它失败了，除非我在我的机器上安装了 xcode）。但重点是，每次我在build.gradle.kts 中的cocoapods 中添加pod 部分时，我的同步都会失败：

Exception in thread "main" java.lang.Error: /var/folders/6p/0kpnx2mj22589gthf1dddjwhtr2_tq/T/15810392041507337443.m:1:9: fatal error: module 'AFNetworking' not found

当我启动 podspec 时，它会正确生成，我的构建 gradle 文件： 第一：

buildscript {
    ext.kotlin_version = "1.4.31"
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.2.0-beta06"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath "org.jetbrains.kotlin:kotlin-serialization:1.4.31"
        classpath "com.squareup.sqldelight:gradle-plugin:1.4.4"
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
        jcenter() // Warning: this repository is going to shut down soon
        maven { url "https://kotlin.bintray.com/kotlinx" }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

还有那个有cocoapods的：

import org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget

plugins {
    kotlin("multiplatform")
    kotlin("plugin.serialization")
    kotlin("native.cocoapods")
    id("com.android.library")
    id("kotlin-android-extensions")
    id("com.squareup.sqldelight")
}

kotlin {
    android()

    val iOSTarget: (String, KotlinNativeTarget.() -> Unit) -> KotlinNativeTarget =
        if (System.getenv("SDK_NAME")?.startsWith("iphoneos") == true)
            ::iosArm64
        else
            ::iosX64

    iOSTarget("ios") {}
    version = "1.0.0"
    cocoapods {
        summary = "This is sample Summary"
        homepage = "Home URL"

        pod("AFNetworking")
        pod("FirebaseAnalytics")
    }

    val coroutinesVersion = "1.3.9-native-mt"
    val serializationVersion = "1.0.0-RC"
    val ktorVersion = "1.5.3"
    val sqlDelightVersion = "1.4.4"

    sourceSets {
        val commonMain by getting {
            dependencies {
                implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:$coroutinesVersion")
                implementation("org.jetbrains.kotlinx:kotlinx-serialization-core:$serializationVersion")
                implementation("io.ktor:ktor-client-core:$ktorVersion")
                implementation("io.ktor:ktor-client-serialization:$ktorVersion")
                implementation("com.squareup.sqldelight:runtime:$sqlDelightVersion")
            }
        }
        val androidMain by getting {
            dependencies {
                implementation("androidx.core:core-ktx:1.3.2")
                implementation("io.ktor:ktor-client-android:$ktorVersion")
                implementation("com.squareup.sqldelight:android-driver:$sqlDelightVersion")
                implementation("com.jakewharton.timber:timber:4.7.1")
            }
        }
        val iosMain by getting {
            dependencies {
                implementation("io.ktor:ktor-client-ios:$ktorVersion")
                implementation("com.squareup.sqldelight:native-driver:$sqlDelightVersion")
            }
        }
    }
}

android {
    compileSdkVersion(29)
    defaultConfig {
        minSdkVersion(24)
        targetSdkVersion(29)
    }
    sourceSets["main"].manifest.srcFile("src/androidMain/AndroidManifest.xml")
}

也许有人已经找到了解决方案？

Answer 1

你跑pod install了吗？

Gradle 需要源代码来生成 kotlin 头文件。

因此，在向 gradle 文件添加新的 pod 依赖项后，您需要运行第一次同步，这将失败，但它会更新您的 podspec 文件。然后你需要运行pod install获取源代码，然后再次运行同步。
