You might run into problem with that approach. In Java the path
name of the file defined what package it should be inside of.
The best thing to do is something like this.
cd TREE_ROOT
jikes pkg1/*.java pkg2/*.java pkg3/subpkg3/*.java -d COMPILED_ROOT
Where TREE_ROOT is the root of your source tree (the place where
the com directory in a com.something package lives) and the
COMPILED_ROOT is the location where the resulting .class files
will go.
I hope that helps.
