JOSM Plugins extend or modify the feature set of the JOSM editor.

Installation

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. This will download the latest version of each plugin.
  5. Click the "Ok" button. This will install the plugins.
  6. 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: %APPDATA%\JOSM\plugins on Windows, or /home/$USER/.local/share/JOSM/plugins (or in case of older installations /home/$USER/.josm/plugins) on Linux, or Users/<YourName>/Library/JOSM/plugins on MacOS.
