Compiling java files in all subfolders?

Question

How to compile all java files in all subfolders on Unix, using javac?

Answer 1

On Windows...

Create a batch file:

for /r %%a in (.) do (javac %%a\*.java)

...then execute it in the top-level source folder.

On Linux...

javac $(find ./rootdir/* | grep .java)

But as others suggested, a build tool would probably prove helpful.
