I've started to lay down some build scripts within each module for people who use the command line (as opposed to Eclipse) for development.
These 'module builds' assume that you have a working Harmony JRE in the deploy/jre directory, and the associated VM overlaid. Steps for this 'bootstrapping' build should be familiar, and are described on the website[1]. Once you have the initial Harmony JRE built you can work in a single module and compile (using the Harmony JRE & Eclipse compiler) and test changes to just that module. So, for example, if I want to work in NIO, I can 'cd' into modules/nio and hack on the source code and tests in there, compile the NIO code by typing 'ant' in modules/nio/make, and test by typing 'ant test' in that same dir. NB: The compile step replaces the nio.jar in the deploy/jre/lib/boot directory (so if you really screw up you'll have to revert and run the global build again!)
