How to exclude java source files in doc task?

Question

I'm using sbt 0.11.2 for a mixed Java/Scala project. I've realized that when I run the doc command from within sbt, it does not only create the scaladocs for the Scala source files in src/main/scala, but also for the Java source files in src/main/java (the sbt wiki claims to create them for src/main/scala only that seems not true).

However, this does not look very well. For instance, for a Java class named Foo with static methods there are two entries in the generated scaladoc: a Foo class and a Foo object. The class only lists the constructor and the object lists the static methods.

Is there any way I can tell sbt to exclude the src/main/java folder from the scaladoc generation? I want to create javadocs for those instead.

The usual way to handle that is to use inspect to see where the information is coming from, and then change it. Inspecting at doc shows compile:sources(for doc), which is a Seq[java.io.File], and can be changed like this:

sources in (Compile, doc) ~= (_ filter (_.getName endsWith ".scala"))

You can use show compile:sources(for doc) to see what it contains, and then set to change it and check again its value.
