== Release ==
The latest release is JOSM 1.5. Get it at: http://josm.openstreetmap.de/download/josm-1.5.jar. The hotlink to the always latest release is http://josm.openstreetmap.de/download/josm.jar

== Nightly Builds ==
You can always grab the latest nightly build - version from http://josm.openstreetmap.de/download/josm-latest.jar. It is usually pretty stable too.

== Getting the Source ==
JOSM is available under GPL, and so of course you can get the sources and compile, modify or redistribute it by yourself. You can grab the sources via [http://subversion.tigris.org subversion]

 svn co http://josm.openstreetmap.de/svn josm

''Hint: If you don't like those funny ''`.svn`'' directories, use ''`svn export`'' instead of `svn co`''

Or you can inspect single files over the web frontend at http://josm.openstreetmap.de/svn.

== Compiling ==
To build the source the easiest way, use eclipse and the provided `.project` and `.classpath` file. Just add a new Java Project using the JOSM source folder as existing path.

You can also build it without eclipse. To do so, change into the `src/` folder and call `javac` on the file `org/openstreetmap/josm/Main` with all libs from `../lib/*.jar` in your classpath (you have to specify all subsequent). If running linux, be sure to have your `JAVA_HOME` set. 

As example, this could look like:
{{{
 $ cd ~/src
 $ svn co http://josm.openstreetmap.de/svn josm
 ''tons of output here''
 $ export JAVA_HOME=/usr/local/jdk1.5.0
 $ cd josm/src
 $ javac -cp .:../lib/MinML2.jar:../lib/metadata-extractor-2.3.1.jar:../lib/gettext-common-0.9.jar org/openstreetmap/josm/gui/MainApplication.java
}}}

=== Compiling with ant ===
Much more comfortable is it to use "ant".[[BR]]
First of all you have to set your JAVA_HOME. Than change into the src folder and just type "ant".[[BR]]
This will compile JOSM automatically and a "Josm_custom.jar" can be found under "/dist"


== Running ==
=== Microsoft Windows ===
Double clicking on the jar file. 

If this does not help, you probably need to install [http://java.sun.com Java]

If you want to be able to handle more points in JOSM you can create a shortcut like the following example:
{{{
C:\WINNT\system32\java.exe -jar -Xmx512M "C:\PATH-TO-JOSM\josm-latest.jar"
}}}

=== Linux / *BSD ===

 '''using the shell'''::
  Go to the directory where the josm-latest.jar is and type
{{{
#!sh
java -jar josm-latest.jar
}}}
  to launch. Replace `''josm-latest.jar''` with the name of the jar file you loaded, e.G. `josm.jar` for releases.

  If this don't help, try to set you JAVA_HOME variable to the java location (the root location, not the bin. As example:
{{{
#!sh
 export JAVA_HOME=/usr/lib/sun-j2se5.0-jdk
 java -jar ''josm.jar''
}}}

 '''KDE'''::
  There is a [http://josm.openstreetmap.de/download/tutorials/setting_up_kde.avi tutorial] on how to setup your environment to start jar-files by clicking on them.

 '''GNOME'''::
  Right click on the JAR file, and select __O__pen with "Sun Java 5.0 Runtime", or whatever java version you have.

 '''XGL/Compiz'''::
  Type this into a shell:
{{{
#!sh
export AWT_TOOLKIT=MToolkit && java -jar josm-test.jar
}}}
  as described here: http://kubasik.net/blog/index.php/2006/06/19/java-sun-150-and-xglcompiz-on-ubuntu/

=== MacOS ===
Just click on the jar-file.
