Kotlin MultiPlatform - 发布 Android 库失败

8

我正在尝试使用新的Kotlin MultiPlatform设置发布Android库(debug/release)。我可以成功地发布iOS框架，但无法发布Android库。以下是我遇到的错误：

配置项目“：shared”时发生问题。

无法通知项目评估侦听器。 Kotlin目标“android”尝试为不是库变体或不存在的Android构建变体设置发布： * release * debug 请检查“publishLibraryVariants”属性，它应指向现有的Android库变体。不支持应用程序和测试变体的发布。

但是，在我的Android Studio中，我可以清楚地看到这些变体。我也能够在Android Studio中使用库依赖项作为项目依赖项运行Android / IOS应用程序

implementation(project(":shared"))

仅在尝试发布时遇到问题。

这是我的 build.gradle.kts 文件:


plugins {
    kotlin("multiplatform")
    kotlin("plugin.serialization")
    id("com.android.library")
    id("kotlin-android-extensions")
    id("com.squareup.sqldelight")
    id("dev.icerock.mobile.multiplatform-resources")
    `maven-publish`
}

group = "com.sekhar.testkmp"
version = "0.1"
val coroutinesVersion = "1.3.9-native-mt"
val serializationVersion = "1.0.0-RC"
val ktorVersion = "1.4.0"
val sqlDelightVersion: String by project

应对此问题的最常见解决方法是在应用 kotlin 多平台插件之前先应用 android 插件：id("com.android.library")：kotlin("multiplatform")。

plugins {
    id("com.android.library")
    kotlin("multiplatform")
    kotlin("plugin.serialization")
    id("kotlin-android-extensions")
    id("com.squareup.sqldelight")
    id("dev.icerock.mobile.multiplatform-resources")
    `maven-publish`
}
