NetBeans generates Javadoc for all packages in the project. Adding the "-exclude" Javadoc option in the documentation form of the project properties under "Additional Javadoc Options" does not seem to work. How do I tell netBeans to exclude a specific package from the Javadoc?
I would try edit -javadoc-build target in the ant build script. On the Files tab browse your project and find nbproject/build-impl.xml, in this file find -javadoc-build target and replace ${excludes} variable in the fileset attribute called excludes with your desired package.
