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.
