Javadoc找不到用scala编写的类

我正在从事一个混合了java和scala代码的项目。我使用maven进行依赖关系管理，使用IntelliJ IDEA进行开发。 我已经添加了用于生成java文档的maven javadoc插件。但是，它无法找到所有scala类。它不断抛出如下错误：

我的目录结构如下：

我能够编译项目并运行它。我只是想知道如何摆脱这些警告？如何让javadoc能够找到scala类？

提前谢谢。

我不认为JavaDoc应该能够为Scala生成文档——这就是ScalaDoc的用途。也就是说（没有个人经验支持这一点），我会告诉你，在搜索更多信息后，我发现了两个stach溢出问题。链接是和
