How to include *.java source files in hxjava build?

I have a couple of macro generated Java source files, but I can't seem to find any doc on how to include them while building Haxe for Java. The only thing I can is how to add *.jar files as library.

No file or test names are provided. Start by reviewing hxjava's build scripts and support code, tracing how JAR libraries are currently included and where macro-generated Java sources enter the build; document the supported entry point and verify it with a Java build.
