Question

在Kotlin / Native示例项目中，由于未解决的依赖关系，我收到了gradle构建错误。

无法解决：org.jetbrains.kotlinx：kotlinx-serialization-runtime-native：0.8.1-rc13

我的build.gradle（通用模块）看起来像

java.lang.NullPointerException

Build.gradle（平台-Android级）

apply plugin: 'kotlin-platform-common'
apply plugin: 'kotlinx-serialization'
repositories {
mavenCentral()
maven { url "https://kotlin.bintray.com/kotlinx" }
jcenter{ url "https://jitpack.io" }
jcenter()
maven { url "https://dl.bintray.com/jetbrains/kotlin-native-dependencies" }
maven { url "http://kotlin.bintray.com/kotlin-dev" }
maven { url "https://dl.bintray.com/kotlin/kotlin-eap" }
maven { url "https://dl.bintray.com/sandwwraith/libs-preview/"}
mavenLocal()

}

dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-common:$kotlin_version"
implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation "org.jetbrains.kotlinx:kotlinx-serialization-runtime-native:$serialization_version"

}

}

项目级别Build.gradle如下：

apply plugin: 'com.android.application'

我可以使用哪些正确的版本和存储库来进行序列化？

Answer 1

您附加的设置有点奇怪，因为您将Kotlin / Native的'konan'插件与'kotlin-platform-common'插件应用于同一模块。首先，不赞成使用“ konan”，而用“ kotlin-platform-native”代替。其次，这些插件应应用于不同的gradle模块，请参见kotlin multiplatform reference。

关于序列化，它现在有两种形式：一是因为Kotlin 1.2的版本号为0.6.x（1.2.70为0.6.2），并且不支持Kotlin / Native。只能提供单独的json parser。第二种口味，因为Kotlin 1.3处于开发阶段，编号为0.8.x-rc13（对于Kotlin / Native 0.9.2，最新数字为0.8.1-rc13），并且确实在单独的工件中包含K / N支持，坐标为“ kotlinx-serialization-runtime-native”。 Kotlin 1.3预览版的序列化文档揭示了更多信息：https://github.com/Kotlin/kotlinx.serialization/blob/master/docs/eap13.md。

还有一个专用的example of setup，其中包含带有序列化的多平台项目的即用型存根。分支native_preview使用上述的Kotlin 1.3-rc，K / N 0.9.2和序列化0.8.1。

无法解决以下项的依赖项：无法解决org.jetbrains.kotlinx：kotlinx-serialization-runtime-native：0.8.1-rc13
