Osmosis not working with mapfilewriter plugin
openstreetmap
Solution
After much trial and error, I finally made it work by downloading Osmosis version 0.40.1 here.
In addition, I've added 4 jar files in the /lib/default folder:
- mapsforge-map-writer-0.3.0-jar-with-dependencies.jar
- mapsforge-map-0.3.0-jar-with-dependencies.jar
- trove-3.0.3.zip
- jts-1.8.jar
After which, i created a new conf file named "osmosis-plugins.conf" and added a line " org.mapsforge.map.writer.osmosis.MapFileWriterPluginLoader" in it.
After doing these steps, Osmosis finally works (though I'm not sure if this is the most correct way of doing it).
However, I still don't really understand why the latest version of Osmosis does not work.
Hope this can help those who faced a similar problem as me!
Problem
I've recently downloaded Osmosis to convert .osm.pbf files to .map files. I'm using Windows 7 for this application. I've downloaded the latest zip file from their system and placed the mapfilewriter jar files into the /lib/default/ folder. However, I keep receiving this error when I run this statement in the .bat file: ``` osmosis --read-pbf file=taiwanlatest.osm.pbf --mapfile-writer file=helloworld.map Mar 19, 2013 7:34:49 PM org.openstreetmap.osmosis.core.Osmosis run INFO: Osmosis Version 0.42 Mar 19, 2013 7:34:49 PM org.openstreetmap.osmosis.core.Osmosis run INFO: Preparing pipeline.

I've tried to use Osmosis version 0.40 and I've gotten this error when I run the .bat file: ``` Error: Could not find or load main class org.codehaus.classworlds.Launcher ``` Where exactly did I go wrong?
