【中文标题】SQLDelight：Kotlin Multiplatform App 中未解决的参考 AndroidSqliteDriver

【英文标题】：SQLDelight: Unresolved reference AndroidSqliteDriver in Kotlin Multiplatform App

【问题描述】：

我尝试将 sqldelight 添加到我的 Kotlin 多平台应用程序，但 androidSqliteDriver 未解析引用。我不明白为什么。 我清除缓存并重新生成所有内容，但它也不起作用。

AndroidSqliteDriver：

package com.rompos.deactivator

import com.squareup.sqldelight.android.AndroidSqliteDriver
import android.content.Context

lateinit var appContext: Context

actual fun createDB() : Server 
val driver = AndroidSqliteDriver(Server.Schema, appContext, "Server.db")
return Server(driver)

build.gradle(common):

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

plugins 
kotlin("multiplatform")
id("com.squareup.sqldelight")


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 = "SharedCode"
        
    


jvm("android")

// Common Main
sourceSets["commonMain"].dependencies 
    implementation("org.jetbrains.kotlin:kotlin-stdlib-common")
    implementation("io.ktor:ktor-client-core:1.3.2")
    implementation("com.squareup.sqldelight:runtime:1.4.0")


// Android Main
sourceSets["androidMain"].dependencies 
    implementation("org.jetbrains.kotlin:kotlin-stdlib")
    implementation("com.squareup.sqldelight:android-driver:1.4.0") 
        exclude(group = "com.squareup.sqldelight", module = "runtime-jdk")

我使用： 等级：6.1.1 毕业插件：4.0.1 科特林：1.3.72 更新：添加代码

【问题讨论】：

请添加代码图像不起作用！

我添加代码，img 不起作用。

【参考方案1】：

你只有一个 jvm 目标 jvm("android") 而不是一个 android 目标。您需要一个 android 库或应用程序目标才能使用 android 库。

编辑：添加 android 目标：

//build.gradle(common)
plugins 
    ...
    // assuming your building a library. use application otherwise
    id("com.android.library") 
    id("kotlin-android")

...
android 
     // fill in your library or app info here


kotlin 
    android  // creates androidMain/Test source sets
        // ex: publishLibraryVariants("release", "debug")
    

    ios()  ...  

    val commonMain by getting  ... 
    val androidMain by getting  ... 
    ...

【讨论】：

我真的很愚蠢，因为我看不到我在哪里指定 jvm(android) 并且我不知道在哪里或如何指定 Android 目标。有人可以发布一个例子。我有一份 kmm-networking-and-data-storage-final 示例的副本，由于同样的原因，该示例不再编译。

【参考方案2】：

确保您至少使用 Android Studio 4.1。 你应该只需要在你的公共 build.gradle 中包含 SQLDelight 插件。

build.gradle

...
apply plugin: "com.squareup.sqldelight" in the common build.gradle
...

sourceSets 
    commonMain.dependencies 
        ...
        // SQL Delight
        implementation "com.squareup.sqldelight:runtime:$Versions.sqlDelight"
        implementation "com.squareup.sqldelight:coroutines-extensions:$Versions.sqlDelight"
    

    androidMain.dependencies 
        ...
        // SQL Delight
        implementation "com.squareup.sqldelight:android-driver:$Versions.sqlDelight"
        implementation "com.squareup.sqldelight:coroutines-extensions-jvm:$Versions.sqlDelight"
    

    iOSMain.dependencies 
        ...
        // SQL Delight
        implementation "com.squareup.sqldelight:ios-driver:$Versions.sqlDelight"
