Hello

   I was trying to convert .osm to .map file. I downloaded and build 0.40 version of osmosis. the below is the error message I am getting.

Hi,

It seems you're using wrong reading task at osmosis.
The --rb task is for reading binary files (e.g. .osm.pbf).
For xml osm files (like in your command) you need the --rx task.

osmosis --rx file=country.osm --s --mw file=country.map type=hd bbox=minLat,minLon,maxLat,maxLon tag-conf-file=tag-mapping.xml
is different from
osmosis --rb file=country.osm.pbf --s --mw file=country.map type=hd bbox=minLat,minLon,maxLat,maxLon tag-conf-file=tag-mapping.xml

Also you need to take care of tag mapping xml. If you don't provide any, then the default one is used.
If your osm has custom tags then you have to implement your own tag mapping xml, otherwise the produced map will be empty.

Regards.
