I'm not sure why I can't process this right now, but I have four packages in one source folder:
./src/common
./src/server
./src/client
./src/unittest
Common uses no files from any of the others, but server and client use files from the common package. In each of the files in those packages I have import common.*. But when I run the compiler with javac ./src/server/*.java it can't find the common package.
The only info I can seem to find is for tree structured package hierarchies, but how do I reference something at the same folder height as me? Do I need to nest common inside both server and client? That seems likely to generate a lot of redundant code.
I'm sure this is probably a question someone has asked before, so I apologize, but I cannot find it anywhere.
