Here's my updated build-user.xml file that lets me build a Reprap.jar file. Once I have developer access on SourceForge I'll update it there.
With this file, you can do
ant jar
to create the Reprap.jar file, and
ant run
to run the Reprap software from that .jar file. The full list of targets is:
build
clean
help
init
jar
properties
run
A tweak to Eclipse lets you use Ant as a builder instead of the default builder, so you can then regenerate the .jar from inside Eclipse, if you are a Java developer. OK, now here's build-user.xml -- comments and suggested improvements welcome, I'm not really a Java programmer!
