Download of Erweiterungen/Plugins failed

[afisch | afisch@…]

What steps will reproduce the problem?

1. During Start up, see (the hopefully) attached snip_007.jpg)

2. OR by trying to load an Plugin (for instance PdfImport), see snip_006.jpg. The message 'Der Filter liefert keine Ergebnisse' appears after using the button 'Liste herunterladen'.

What is the expected result?

A list with all plugins/filtered plugins should appear, and plugin Measurement should be updated, or loaded, etc.

What happens instead?

See pictures, Doenload or actualisation of plugins not possible.

Please provide any additional information below. Attach a screenshot if possible.

I hope I will get the oppotunity to upload two screenshots; up to now I am only able to announce that 'Ich habe Dateien, die ich an dieses Ticket anhängen möchte'.

This seems odd. Have you restarted JOSM?

EDIT: java.lang.NoClassDefFoundError: org/openstreetmap/josm/data/SelectionChangedListener was deleted back in 2018 (see r14247). When was the last time that you updated JOSM prior to this?

FTR: Measurement was fixed in r34529/osm
