Install osm2map manually

since there have been many instances of people, not being able to install osmosis and the mapsforgs map writer plug-in over the dedicated script, I've just de constructed the script here so it can just be copy pasted into the terminal.

(this script was originally made by Tom Morelly in 2019 and updated in 2020)

Please remember to run in sudo

1. installing and setting up osmosis
   cd /opt
wget https://bretth.dev.openstreetmap.org/osmosis-build/osmosis-0.47.tgz
mkdir -p osmosis
mv osmosis-0.47.tgz osmosis
cd osmosis
tar xvfz osmosis-0.47.tgz
rm osmosis-0.47.tgz
chmod a+x bin/osmosis\

2. installing mapwriter plugin
   cd /opt/osmosis/lib/default
curl -L -O https://search.maven.org/remotecontent?filepath=org/mapsforge/mapsforge-map-writer/0.9.1/mapsforge-map-writer-0.9.1-jar-with-dependencies.jar\

to use the mapwriter plugin: /opt/osmosis/bin/osmosis --rx file=path-to-osm-file.osm --mw file=destination-path-map-file.map
