-metatypeannotations instruction tells bnd which bundle classes, if any, to search for Metatype Service annotations. bnd will then process those classes into Metatype XML resources.
The value of this instruction is a comma delimited list of fully qualified class names.
The default value of this instruction is
*, which means that by default bnd will process all bundle classes looking for Metatype annotations.
The behavior of Metatype annotation processing can be further configured using the -metatypeannotations-options instruction.
