Osmosis doesn't find the plugin

[Rob Black]

Hello everybody,

I am trying to get the mapsforge mapwriter plugin to work with Osmosis 0.42-6.
I am working on a Windows 8 machine and the installation paths are as follows:

Plugin dir:
C:\Users\Rob\.openstreetmap\osmosis\lib\plugins\mapsforge.jar

Install path osmosis:
D:\Downloads\osmosis\

Now my rendering command and the errors I get:
D:\Downloads\osmosis>bin\osmosis --rb file=data\germany-latest.osm.pbf --mapfile-writer file=tmp\germany-latest.map type=hd

I think, the problem is that the plugin is not found. I also copied it into the install dir of osmosis as mentioned above, but that doesn't worked for me either. Then I tried the "-p" command as mentioned in another post, but the only thing I get is unable to load class. I've installed the newest version of trove into the osmosis default libs, but that doesn't help a thing.

Please give me some advice.
Best Regards
Rob

IMO only older osmosis versions will work: " tested with Osmosis 0.36 - 0.40.1"

Hi Peter,
thanks for the advice. I downloaded Osmosis 0.40.1 now, but it seems like nothing has changed. I get the same errors, it doesn't matter which form of plugin implementation I use.
Greetings,
Rob

I think you have two different errors:

1. For the first you give the stacktrace, there it does not seem to find your plug-in, so something in the path is wrong. I do not use Windows, so I cannot help with this.
2. You say, that if you use the -p option, it gives you a different error, unable to load class. I think this might be resolved if you use osmosis < 0.41. What is the exact error message you get there?

Hi Ludwig,
the exact error when I try it with Osmosis 0.40.1:

I have copied the mapsforge.jar to the \bin\ dir, but that doesn't work either. Any ideas?
Greetings,

[Ludwig]

I think you need the mapfile writer jar.

http://ci.mapsforge.org/job/mapsforge/lastSuccessfulBuild/artifact/mapsforge-map-writer/target/mapsforge-map-writer-0.3.1-SNAPSHOT-jar-with-dependencies.jar

[Robert Schwarz]

The mapsforge.jar is the maps writer jar. I just renamed it to not to write too much in the cmd. Could this be the cause?

No, that would not be the cause.

A simple way to make osmosis work with mapsforge is:

- Copy mapsforge-map-writer-0.3.1-SNAPSHOT-jar-with-dependencies.jar (from Ludwig's link) at "osmosis/lib/default" folder
- Create a text file "osmosis-plugins.conf" at "osmosis/config" folder (if it isn't already exist)
- Add this line to the text file:
org.mapsforge.map.writer.osmosis.MapFileWriterPluginLoader

[Martin Vennekamp]

Thanks this finalyworked for me! (win7)

@Emux

when I do what you have suggested, I get this error:

 org.openstreetmap.osmosis.core.OsmosisRuntimeException: Task type "mapfile-writer" already exists.

WHat shall I do ?

[Emux]

In newer versions we include the proper plugin info for Osmosis inside the Mapsforge plugin.

So all you have to do now is putting the latest map writer plugin jar inside latest Osmosis lib/default folder.
(Make sure you have only one map writer in Osmosis class path)

You probably have two writer jars on your path...

Hi Emux & Ludwig,

I installed osmosis via brew on mac book pro macOS Sierra (10.12.3).
I placed the "mapsforge-map-writer-0.7.0-jar-with-dependencies.jar" in the folder "/usr/local/Cellar/osmosis/0.45/libexec/lib/default/".
I get the following error message

Please can you suggest how to trouble shoot the issue.

Thank you

[Emux]

As seen in map-writer plugin installation section you can have a look at Osmosis documentation for more convenient ways to install plugins.

Regarding the exception it probably needs to provide a bounding box (see also map-writer docs).
