The creation of the map file works fine. What could be the reasons for the POI creation failure?

Try with Osmosis 0.47.

Testing the following command with Java 11, it works fine.

map-creator.sh europe/andorra ram en,de,fr,es 2

Same problem. Maybe the problem is caused by the latest snapshot map/poi-writer from https://oss.sonatype.org/content/repositories/snapshots/org/mapsforge/

I will try to find older releases of the plugins.

I tried different plugin versions (0.15, 0.16) but both fail with the same error. Is there maybe something else to change in the "map-creator.sh" script?

Removing the following from the "https://github.com/mapsforge/mapsforge/blob/master/mapsforge-poi-writer/src/main/config/poi-mapping.xml" fixes the problem:

xmlns="http://mapsforge.org/poi-mapping" xsi:schemaLocation="http://mapsforge.org/poi-mapping https://raw.githubusercontent.com/mapsforge/mapsforge/master/resources/poi-mapping.xsd"

The test was done with Osmosis 0.47 and Java 11 on linux and the latest map-writer / poi-writer and everything works fine.
(like we build them at the server all this time)

mapsforge-map-writer-master-20210527.154736-408-jar-with-dependencies.jar
mapsforge-poi-writer-master-20210527.154751-408-jar-with-dependencies.jar
(which are the current 0.16 releases)

You can run the POI command (see the documentation) outside mapsforge-creator.
There could be some issue in the local environment that needs to be fixed.

I use a complete fresh Ubuntu installation. But removing the namespace definition from the XML file fixes the problem for me.

On another system it works without problems. Seems to be a local environment issue indeed.

What Java distribution and version do they have, AdoptOpenJDK 11 LTS?

OpenJDK 14. On the other system where it works there is OpenJDK 11 installed (64 versions on both systems).
