SQLDelight：Kotlin Multiplatform App中未解决的参考AndroidSqliteDriver

问题描述

我尝试将sqldelight添加到我的Kotlin Multiplatform App中，但未解析AndroidsqliteDriver参考。我不明白为什么。 我清除了缓存并重新生成了所有文件，但它也无法正常工作。

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（常见）：

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")
}
}

build.gradle（android）：

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'
apply plugin: 'kotlinx-serialization'

}

build.gradle（项目）：

buildscript {
ext {
    ext.kotlin_version = '1.3.72'
    sqldelight_version = "1.4.0"
}
repositories {
    google()
    jcenter()
    mavenCentral()

allprojects {

    google()
    jcenter()
    maven { url "https://kotlin.bintray.com/kotlinx" }
}
}

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

我使用： gradle：6.1.1 gradle插件：4.0.1 科特林：1.3.72 upd：添加代码

解决方法

您只有一个 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：添加一个安卓目标：

//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 { ... }
    ...
}

,

确保至少使用 Android Studio 4.1 。 您只需要在常见的build.gradle中包括SQLDelight插件即可。

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}"
    }
}
