Run ant with -debug and you should see why javac is compiling everything
again.

It has to do with this attribute
 srcdir="${cms.java.dir}/com/comp/cms/cmscontroller"

This should point to the root of your package hierarchy.
 srcdir="${cms.java.dir}"

Use include elements to select particular packages.
