为什么 Maven 阴影会跳过 MCCoroutine 库中的文件

Question

运行我的 Spigot 插件（使用 Kotlin 和 Maven 构建）时，我收到有关缺少类的错误。

我的 .jar 中缺少文件“com.github.shynixn.mccoroutine.bukkit.impl.MCCoroutineImpl”。正如在 jar 结构中运行命令

ls -R

时所看到的那样。但文件夹“impl”确实包含一个名称奇怪的文件，这可能与此有关。

./com/github/shynixn/mccoroutine/bukkit/impl: 'CoroutineSessionImpl$init$inlined$Runnable$1.class'

如何解决这个问题？

我联系了图书馆所有者这个问题。

实施细节：

• 科特林 v1.9.0
• Kotlin 插件 232-1.9.20-release-507-IJ10072.27
• Maven 阴影插件 v3.5.1（也出现在 v3.5.0 上）
• Maven编译器插件v3.11.0
• 我正在使用

  minimizeJar

构建我的 Spigot 插件（使用 Kotlin 和 Maven 构建）时 - Maven 不会记录任何错误。这是输出：

[INFO] Including com.github.shynixn.mccoroutine:mccoroutine-bukkit-api:jar:2.13.0 in the shaded jar. [INFO] Including com.github.shynixn.mccoroutine:mccoroutine-bukkit-core:jar:2.13.0 in the shaded jar.

当我运行插件时，我收到以下错误：

此问题的解决方案（不是最干净的）是将这个包中的所有文件包含到阴影 .jar 中。
