Non-functional plugins

[map88]

I followed along with the plugin installation instructions on the website exactly and can see mapillary, building tools, and a few other plugin files in ~/.local/share/JOSM/plugins. I can see these plugins being initialized when JOSM starts up. However, they don't appear in the installed list nor do they seem to add in any of their expected functionality.

Also probably worth mentioning the program was installed from the arch repos.

Stupid question: do you gave a ~/.josm directory?
If so, try renaming that.

[map88]

I do not have a .josm directory.

I'm having the exact same issue but on Windows. The plugins are placed in the plugin folder, and they show up in the processing file list, yet they don't make any changes the plugins said they would do, nor do they show up in the installed plugins list. It may be important to note that plugins that were already installed a while before are visible and can still function after updating the plugins, but newer plugins don't show up as installed. I'm thinking it might have to do with the specific version of JOSM installed, so I'm thinking about using an earlier version of JOSM to see if that's the issue.

[ExecutableFiles]

Update, I tested it on older versions and it doesn't seem to work there. Don't know if its just because its an older version and JOSM doesn't want plugins installed on that version, or if something else is going on like if the issue was server side.

Do you mind uploading one of the nonworking plugin jar files?

PDFimport plugin

The PDF import plugin is the one I personally have been trying to get working, but the same issue occurs for many other plugins
