Having used SVN to install the whole of the build directory into ~/josm, the developer's Wiki says:-
The easiest way to compile JOSM ... is to go to the josm directory and type:
Hah! This is what happened to me:
~$ cd josm ~/josm$ ant Unable to locate tools.jar. Expected to find it in /usr/lib/jvm/java-8-openjdk-amd64/lib/tools.jar Buildfile: build.xml does not exist! Build failed
The reason for the error is that I've only got the JAVA-7 JDK installed (the default JRE is JAVA-8, but that is the runtime environment, and it is the development kit that is needed here):
~/josm$ locate /tools.jar /usr/lib/jvm/java-7-openjdk-amd64/lib/tools.jar
The fix is to install the missing openjdk-8-jdk, which I do via Synaptic. The result is still disappointing:
~/josm$ ant Buildfile: build.xml does not exist! Build failed
This is getting boring.
build.xml is the buildfile (configuration-file) for the compiler. It's default location is within the root of the directory from which the compiler is launched (./). Naturally, there isn't a buildfile in the base directory, though there is within
core/ & other directories. Which one to use? Who knows?
I try to use an intelligent pin:

That is a horrible, large number of warnings, but it works now!
