Packaging WAR with Java and Scala sources - scala

Question

I would like to ask you simple question. Is it possible to package WAR file which will contain Scala and Java sources, each from separate source directory (src/main/java/... and src/main/scala/...)? Of course, I still like to contain other resources like images and static pages into resulting WAR.
I've been looking into WAR plugin capabilities, regarding additional sources, but I didn't find anything helpful in this area. Can anyone give me a hint, where should I look for solution, or perhaps any kind of help?
Thanks,
Matthew

Here is a cut down version of the pom I use for my multi-language projects.

After running mvn clean package inside that directory, with a scala source in src/main/scala and a java source file in src/main/java this is what I get. And as you can see the scala and java files have both been compiled into the war.
