如何强制SBT使用Javadoc而不是Scaladoc？

我有一个基于Java的Play&Akka项目，它是用SBT构建的，在构建项目时，有没有办法告诉SBT运行Javadoc而不是Scaladoc？SBT文件中说

如果项目中只有Java源，sbt将运行javadoc。如果有任何Scala源，sbt将运行scaladoc

---

项目中没有Scala文件，但Scaladoc仍在运行。我假设这是因为Play插件正在编译之前将视图模板和

conf/routes

文件转换为Scala代码。

您可以尝试集成到sbt中，以便生成javadoc

ScalaDoc仍然可以使用正常的

doc

任务生成，
而JavaDoc可以使用genjavadoc:doc生成

---

tl；dr更改（Compile，doc）中的

源代码以排除
*.scala
文件，这样scaladoc就不会生效

正如您可以在（Compile，doc）中阅读到的
源文件
保存项目中的所有托管和非托管源文件：

> inspect compile:doc::sources
[info] Task: scala.collection.Seq[java.io.File]
[info] Description:
[info]  All sources, both managed and unmanaged.

使用一些
过滤器
ing，您可以非常轻松地实现目标-在
build.sbt
中使用以下内容：

sources in (Compile, doc) <<= sources in (Compile, doc) map { _.filterNot(_.getName endsWith ".scala") }

和允许的另一种方法是让
scaladoc
运行！它将处理javadoc注释

Scaladoc已经处理Java源代码并为它们生成Scaladoc。

它只是忽略了文档注释

出于各种原因，我们的许多Scala代码库中至少包含一些Java。

如果Scaladoc能够为这些混合代码库生成完整的文档，包括所有文档注释，那就太好了
