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
