Hi Artur, Beware that packaging gpsmaster won't be trivial, some of its dependencies are not packaged in Debian yet, and it requires and older version of metadata-extractor which will require patches to work with the newer version in Debian. You may be better off just using the upstream jar which bundles the dependencies.
