如何使用我的 Kotlin 多平台项目发布 javadoc.jar 文件？

Question

我正在尝试发布 my Kotlin multiplatform library to Maven Central via Sonatype. This repository requires me to include a javadoc.jar file with my artifacts. Unfortunately, the IntelliJ IDEA project wizard and the Kotlin multiplatform docs 不要帮我做。当运行 Gradle 任务 dokkaJavadoc（对于官方 Kotlin 文档工具 Dokka）时，我收到错误消息“Dokka Javadoc 插件当前不支持为多平台项目生成文档。”

我实际上不需要真正的 JavaDocs 来发布 - 一个空的 javadoc.jar 或一个由 Dokka 生成的其他文档就足够了。由于我是 Maven 的长期用户，而这些是我使用 Gradle 的第一步，我不知道该怎么做。

也发布了 at Kotlin Discussions。

Answer 1

这个答案是 Kotlin Discussions. Credit goes to Lamba92_v2 of the JetBrains Team, who linked his solution in his project kotlingram 的交叉 post。

我注意到我还有另一个与发布相关的问题：签名和 POM 信息未应用于所有模块。但鉴于 Lamba92_v2 的代码，我可以解决所有与发布相关的问题：

如何使用我的 Kotlin 多平台项目发布 javadoc.jar 文件？

How can I publish a javadoc.jar file with my Kotlin multiplatform project?

gradle
