javac option to compile all java files under a given directory recursively

I am using the javac compiler to compile java files in my project. The files are distributed over several packages like this: com.vistas.util, com.vistas.converter, com.vistas.LineHelper, com.current.mdcontect.

Each of these packages has several java files. I am using javac like this:

javac com/vistas/util/*.java com/vistas/converter/*.java
      com.vistas.LineHelper/*.java com/current/mdcontect/*.java

(in one line)

Instead of giving so many paths, how can I ask the compiler to compile recursively all the java files from the parent com directory?

javac -cp "jar_path/*" $(find . -name '*.java')

(I prefer not to use xargs because it can split them up and run javac multiple times, each with a subset of java files, some of which may import other ones not specified on the same javac command line)

If you have an App.java entrypoint, freaker's way with -sourcepath is best. It compiles every other java file it needs, following the import-dependencies. eg:

javac -cp "jar_path/*" -sourcepath src/ src/com/companyname/modulename/App.java

You can also specify a target class-file dir: -d target/.
