Android 未找到Kotlin Multiplatrom移动库的匹配变体

我有一个Kotlin多平台手机，我发布到Maven Central。我还尝试在非KMM Android应用程序中使用此库。当我在android应用程序中声明依赖项时，我得到了这个错误

Execution failed for task ':app:checkDebugAarMetadata'.

我假设我的配置有问题，但我真的不知道这个错误告诉我什么，这是我第一次创建KMM库

signing {
    sign(publishing.publications)

以及添加备用方案

buildTypes {
    getByName("release") {
        isMinifyEnabled = false
    }
    val staging by creating{
        setMatchingFallbacks(listOf("release", "debug"))
    }
}

那没什么用

如果我创建了一个新的KMM项目，并且只尝试添加依赖项，我会发现一个不同的错误，就是

Failed building KotlinMPPGradleModel
org.gradle.internal.resolve.ArtifactNotFoundException: Could not find tweedle-android-0.3.1-samplessources.jar (io.github.tyczj:tweedle-android:0.3.1).

---

我猜你们把图书馆出版成aar。在这种情况下，您应该显式地将@aar添加到gradle依赖项中

implementation 'io.github.tyczj:tweedle-android:0.3.0@aar'

---

当您包含一个不是为正确平台构建的依赖项时，会出现引用“samplessources”的错误消息。在中进行了一些讨论，在本例中，围绕发出更好的错误消息也进行了讨论

---

在您的例子中，它可能是由常见依赖项中的

实现（“ch.qos.logback:logback classic:1.2.3”）

触发的。这是一个JVM库，但您有一个iOS目标，因此它无法在您的通用依赖项中工作。将它移到您的Android依赖项上。

我看到了一个非常类似的错误，我最初认为它与kapt有关，但我没有看到您在这里使用它。如果我在我的项目中使用kapt更改了一些配置，使用

configurations[“kapt”].dependencies.add（..）

而不是

kapt.annotationProcessor（..）

，我就避免了这个问题，但是项目没有在ide中构建，我认为我遇到了jdk11问题（包javax.annotationDNE），尽管在命令行上构建是成功的。我想我可以接受。希望这能给你一些想法。@tyxzj所以我试图在一个新项目中添加你的库，但没有添加。当我运行摇篮依赖关系图时，它显示+---com.tycz:tweedle android:0.3.2失败+---com.tycz:tweedle android调试：0.3.2失败仍然是相同的问题我将此依赖关系添加到我的项目中，并成功编译。这似乎是根本原因——冲突的来源。项目资源是否可用，以便我可以尝试测试自己？这一个适合我。1.注释行//实施项目（':tweedle'）2。添加以下dep。分别用于发布和调试debugImplementation'io.github.tyczj:tweedle android调试：0.3。2@aar“releaseImplementation”io.github.tyczj:tweedle android:0.3。2@aar'我猜您还需要添加库依赖项debugImplementation（'io.github.tyczj:tweedleandroid debug:0.3）。2@aar“）{传递（真）}releaseImplementation（'io.github.tyczj:tweedle android:0.3。2@aar“）{可传递（true）}很抱歉反应太晚。尝试执行以下操作。在Tweedle/app/build.gradle文件中，只保留一个依赖项实现（'io.github.tyczj:tweedleandroid:0.3）。2@aar“{transitive（true）}并将debug部分添加到buildType debug{matchingFallbacks=['release']}嗯，有趣的是，我只是在Ktor中调试请求时使用它，那么这是否意味着我将无法在iOS上记录请求？您可以在iOS上记录请求，但必须使用支持iOS的记录器才能这样做。有一个

Logger.DEFAULT

或

Logger.SIMPLE

内置，可以在iOS上转发到

println（）

，也可以创建自己的日志，转发到您选择的iOS日志API。您的意思是什么~“将其移动到您的Android依赖项。”

implementation 'io.github.tyczj:tweedle-android:0.3.0@aar'
