I think the first problem is that your source dir and destination dir in the javac
task are different.
I'm not 100% sure about that.
In the case of the project for which I am using Ant, I copy all sources in a directory
that I call 'build/compile'
The equivalent would be:
cp -a MySourceDir/* build/compile/
I then have source dir and destinatin dir for the javac task set to the same thing:
build/compile
That way, if there is a .java file build/compile/com/foo/bar/Barbie.java
the compiled class will end up being at build/compile/com/foo/bar/Barbie.class
That is the only way that I was able to prevent javac/jikes from recompiling over 1300
of our .java files every time I use ant to compile things.
If there is a better way I'm all eyes!
