Hello, hopefully this is one of the last things I need currently and you guys have been very helpful so thank you very much.

I can't quite get variable tag values to map correctly. In the Tag mapping schema it says that you can use "%f" for numeric values and "%s" for string values, but in my case none of the tags with values set to "%f" are being mapped.

For example, if I have the following tag mapping in my Custom Tag Mapping XML:
<osm-tag key="towerId" value="%f" zoom-appear="1" />
This tag doesn't get mapped by MapWriter (its not generated in .map file).
If I use some of the actual towerId values like such:
<osm-tag key="towerId" value="551" zoom-appear="1" />
<osm-tag key="towerId" value="552" zoom-appear="1" />
It works fine.

What could be the problem here?

Have you used the tag-values parameter as described in map-writer documentation?

You can check the default tag-mapping and see how the variable tag values are used.

I forgot to add the tag-values parameter. Should this parameter be added only as "tag-values" like such:
osmosis --rx file=input-data.xml --mw file=output-data.map tag-conf-file=customTagMapping.xml bbox=20,20,21,21 tag-values
I tried this and it still doesn't generate tags with variable values.

Have you looked in map-writer documentation?

It is a boolean option: tag-values=true

Yes, tried using it like that also, but I get an error saying "Argument tag-values for task 2-mw was not recognized."

You should debug your code and commands.

And make sure using the latest map-writer jar.

Using latest Osmosis and latest map-writer jar gives me "java.lang.NoClassDefFoundError: gnu/trove/procedure/TShortIntProcedure" error. Is there a trove jar to download and put into plugins folder?

Do you follow map-writer documentation?

(download the jar-with-dependencies)
