SQLDelight: Kotlin多平台应用程序中未解决的引用AndroidSqliteDriver

Question

我尝试在我的Kotlin多平台应用程序中添加Kotlin，但是AndroidSqliteDriver未解决引用。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(公共)：

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")
    }
}

// iOS Main
sourceSets["iosMain"].dependencies {
    implementation("com.squareup.sqldelight:native-driver:1.4.0")
}
}

我使用: gradle: 6.1.1 gradle插件: 4.0.1 kotlin: 1.3.72 upd: Add代码

Answer 1

您只有一个jvm目标jvm("android")，而没有一个android目标。您需要一个android库或应用程序目标来使用android库。

编辑：添加一个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 { ... }
    ...
}

确保您至少使用了AndroidStudio4.1。您只需将SQLDelight插件包含在您的普通build.gradle中即可。

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}"
    }
}
