Exclude code from jar without using exclude

So I have a project, in the project I have my main project with the package structure com.something.stuff. Under that I have several components com.something.stuff.special. The classes under special I am building into their own specific jars using an ant build. When I build the project I do not want the stuff for com.something.stuff.special to be included in the jar. I tried using the exclusion but this makes several of the features of code inspection not work. Is there a way to prevent classes from being added to a jar without using the exclusion feature?
