Steps

 require 'javaclass/dsl/mixin'

1) create the classpath of the given workspace

 cp = workspace(location)
 puts "#{cp.count} classes found on classpath"

define a filter to limit all operations to the classes we are interested in

 filter = Proc.new { |classname| classname.same_or_subpackage_of?(package) }

2a) collect all transitive dependencies of a single class into an AdderTree

 dependencies = cp.transitive_dependency_tree(start_class.to_javaname, &filter)
 puts "#{dependencies.size} classes in transitive dependency graph of class #{start_class}"
 dependencies.debug_print

2b) or collect all transitive dependencies of a whole package

 dependencies = cp.transitive_dependencies_package(start_class.to_javaname.package, &filter)
 puts "#{dependencies.size} classes in transitive dependency graph of package #{start_class.to_javaname.package}"
 dependencies.debug_print
