kotlin - 将 kotlin 多平台库发布到 Maven Central(InvalidMavenPublicationException 多个具有相同...的工件)

Question

由于 Jcenter 即将关闭，我正在尝试将我的库迁移到 Maven Central。我已经搜索了很多找到任何工作脚本，但没有运气。有official docs ，但这就像一个笑话，那里只是告诉放maven-publish gradle 脚本的插件，瞧，就是这样。
目前我收到错误:

Caused by: org.gradle.api.publish.maven.InvalidMavenPublicationException: Invalid publication 'js': multiple artifacts with the identical extension and classifier ('jar', 'sources').

我的脚本如下所示:

plugins {
    id("kotlin-multiplatform")
    id("org.jetbrains.dokka") version "1.4.0-rc"
    `maven-publish`
    signing
}

        linuxArm64()

我也发现这个 reddit topic没有解决办法，这个 article那行不通，还有很多其他人。如何发布到 bintray 的 Material 有很多，但现在都无关紧要了

似乎问题出在这一行 artifact(tasks["sourcesJar"])因为这个任务已经包括在内。
在这里，我想放置用于将 kotlin 多平台库上传到 Maven Central 的工作脚本。
首先，我们需要注册 Sonatype 帐户，验证我们的域等，这里是 fresh article with detailed steps .
然后你的项目脚本 build.gradle.kts可能看起来像这样:

import java.io.FileInputStream
import java.util.Properties
import org.gradle.api.publish.PublishingExtension

plugins {
    id("kotlin-multiplatform")
    id("org.jetbrains.dokka") version "1.4.0-rc"
    id("io.codearte.nexus-staging") version "0.22.0"
    `maven-publish`
    signing
}

enum class OS {
    LINUX, WINDOWS, MAC
}

fun getHostOsName(): OS =
    System.getProperty("os.name").let { osName ->
        when {
            osName == "Linux" -> OS.LINUX
            osName.startsWith("Windows") -> OS.WINDOWS
            osName.startsWith("Mac") -> OS.MAC
            else -> throw GradleException("Unknown OS: $osName")
        }
    }

kotlin {
    sourceSets {
        jvm()
        js() {
            browser()
            nodejs()
        }
        when (getHostOsName()) {
            OS.LINUX -> {
                linuxX64()
                linuxArm64()
            }
            OS.WINDOWS -> {
                mingwX64()
            }
            OS.MAC -> {
                macosX64()
                iosArm64()
                iosX64()
            }
        }

                }
            }
            OS.WINDOWS -> {

在 gradle.properties 中提供所需的库详细信息:

libraryVersion = 0.1.1
libraryName = Your library name
libraryDescription = Your library description
publishedGroupId = com.yourdomain
artifactName = your-cool-librayr
siteUrl = https://gitlab.com/yourlibrayr
gitUrl = https://gitlab.com/yourlibrayr.git
developerId = ...
developerOrg = ...
developerName = Your Name
developerEmail = yourmail@mail.com
licenseName = The Apache Software License, Version 2.0
licenseUrl = http://www.apache.org/licenses/LICENSE-2.0.txt
allLicenses = ["Apache-2.0"]
kotlin.mpp.enableGranularSourceSetsMetadata = true
gnsp.disableApplyOnlyOnRootProjectEnforcement = true

这里 gnsp.disableApplyOnlyOnRootProjectEnforcement = true声明所需的属性 nexusStaging in subprojects .
最后把你的积分放到 local.properties :

oss.user=your_user_name
oss.password=your_pass
signing.keyId=last_8_numbers_of_key
signing.password=your_pass
signing.secretKeyRingFile=/path/to/keystorage.gpg

现在在项目目录中发布开放终端:

./gradlew build
./gradlew publish
./gradlew closeAndReleaseRepository

您可以跳过最后一个命令，并从 Nexus repository manager 关闭和释放暂存包。 .那个nexus-staging插件只需要从命令行执行。

我试图将脚本的发布部分移动到单独的文件中，并将其包含在 apply(from = "publish.gradle.kts") 中。 ，但它没有用，因为它在单独的文件

中丢失了上下文

我使用旧版本的 dokka 库 (1.4.0-rc)，因为新版本无法为所有平台生成 javadoc。存储库需要此 javadoc 才能发布。如 authors mentioned我们可以为此生成空的 javadoc.jar 文件。
