Supplemental information for JOSM -- the Java OpenStreetMap Editor
============================================================================= I. Install & Launch
Installation notes
To run JOSM, you need:
- The JOSM .jar file, e.g., josm-tested.jar or josm-latest.jar
- Java Runtime Environment (JRE) 8, or later.
How to get Java Runtime Environment
You need JRE Version 8, or later.
Microsoft Windows and Apple macOS users should visit one of:
- https://www.azul.com/downloads/?package=jdk#download-openjdk
- https://bell-sw.com/pages/downloads/#mn and download the latest Java executable for their system.
Linux users should visit http://www.oracle.com/technetwork/java/index.html There is a Linux binary installer, which you must execute from a console, or use the mechanism of your distribution's packaging system.
How to launch
Microsoft Windows users launch by double-clicking on the .jar file. If this does not work, open a command shell and type "java -jar josm-latest.jar" in the directory that holds the file. (Please replace josm-latest.jar with the name of your .jar file, if you aren't using the latest version.)
Under Linux, open a shell, go to the file directory and type "java -jar josm-latest.jar" to launch. If this does not work, try to set your JAVA_HOME variable to the java executable location (the root location, not the bin).
macOS users just click on the .jar file icon.
============================================================================= II. Development
How to get the source code
Download it directly from the subversion at https://josm.openstreetmap.de/svn/trunk. To use the command line subversion client, type
svn co https://josm.openstreetmap.de/svn/trunk josm
