科特林多平台。无法访问 class SqlDriver.Schema。检查您的模块 classpath 是否缺少或冲突的依赖项

Question

我正在尝试构建针对 iOS、Android、JS（浏览器）、Mac、Windows 和 Linux 的 KMP 库。现在我只使用 Ktor 和 SQLDelight 作为依赖。但是在为 SQLDelight

创建驱动程序时，在 nativeMain 的实际实现中出现以下问题

虽然相同的代码不会给 iOS main 带来任何问题，它也使用相同的 NativeSqliteDriver（我需要单独使用它们，因为 iOS 和桌面平台的 Ktor 客户端是分开的）。以下是我的 build.gradle.kts

plugins {
    kotlin("multiplatform") version "1.5.31"
    id("maven-publish")
    id("com.android.library")
    kotlin("plugin.serialization") version "1.5.31"

val xcFrameworkName = "AddressLib"

repositories {
    google()
    mavenCentral()

kotlin {
    jvm {
        compilations.all {
            kotlinOptions.jvmTarget = "1.8"
        }
        testRuns["test"].executionTask.configure {
            useJUnit()
        }
    }
    js(LEGACY) {
        browser {
            commonWebpackConfig {
                cssSupport.enabled = true
            }
        }
    }

    val xcFramework = XCFramework(xcFrameworkName)

    val hostOs = System.getProperty("os.name")
    val isMingwX64 = hostOs.startsWith("Windows")
    when {
        hostOs == "Mac OS X" -> macosX64("native") {
            binaries.framework(xcFrameworkName) {
                xcFramework.add(this)
            }
        }
        hostOs == "Linux" -> linuxX64("native")
        isMingwX64 -> mingwX64("native")
        else -> throw GradleException("Host OS is not supported in Kotlin/Native.")
    }

    android()

Answer 1

所以问题似乎是由于相同的依赖项被添加到构建 gradle 两次，并且相应的代码也被添加了两次。为了解决这个问题，我必须制作一个单独的源集，如下所示

val sqlDriverNativeMain by creating {
    dependsOn(commonMain)
    dependencies {
        implementation("com.squareup.sqldelight:native-driver:$sqlDelightVersion")
    }
}
val iosMain by getting {
    dependsOn(sqlDriverNativeMain)
    dependencies {
        implementation("io.ktor:ktor-client-ios:$ktorVersion")
    }
}
val nativeMain by getting {
   dependsOn(sqlDriverNativeMain)
   dependencies {
       implementation("io.ktor:ktor-client-curl:$ktorVersion")
    }
}

然后将驱动程序创建代码移动到名为 sqlDriverNativeMain 的 sourceSet 目录中。这解决了问题。
