Usual, easy method

You can easily install plugins from within JOSM as follows

  1. Start JOSM, open the preferences window (Edit→Preferences or use the toolbar icon) and select the plugins tab.
  2. Click on "Download List" to download the list of available plugins.
  3. Check the plugins you want installed.
  4. Click the update button. All new plugins should start downloading and installing.
  5. Restart JOSM. (Some Plugins work even without a restart. You will be notified, if a restart is required.)

Manually install JOSM plugins

Usually you don't need to install plugins manually! If you do need to install manually:

  • Save plugin jar files in the plugins directory in the JOSM settings directory: ~/.josm/plugins (e.g. /home/$USER/.josm/plugins/wmsplugin.jar) (example paths for Linux)
