This is a reference for setting up a new Ant-based Java project. It contains most of the little Ant tricks I've learned over the years. When I start a new Java project I clone this repository, remove sections of build.xml that I don't care about for that particular project, set the project properties, clear out the sample sources, and get to work.
Building this project requires that Ivy be available to Ant. All you
need is ivy.jar in Ant's classpath (in your $CLASSPATH,
$ANT_HOME/lib, or ~/.ant/lib).
You will need to have Astyle installed and in your path for the "format" target to work. If it's missing, that's fine. It won't affect any other targets.
There is a "hotswap" target for replacing live code while an application is running. You'll need the hotswap Ant extension installed to use it. This target is to be used alongside the "run-hotswap" target, which enables hotswapping in the JVM. You can demo this for yourself by running "run-hotswap" in a terminal, editing the printed string in the code, and running "hotswap" in another terminal. The printed message in the running program should change to the new string.
Take note of the sample pom.xml file. This is not actually for Maven
builds -- this is an Ant project afterall -- but for publishing builds
for a Maven repository. It's packed up by the "bundle" target, which
creates a bundle.jar containing your project's signed artifacts. To
use the "bundle" target you need to have GnuPG set up in your path, a
generated key pair, and a running gpg-agent, unless you like typing
your passphrase a bunch of times in a row.
I hate coding absolute paths in my build script and I hate including built files as part of the base project. My philosophy is that the environment should be set up so that the tool can easily find the external resources they need (JUnit, etc.) from the system or dependency manager. It's the system or dependency manager that provides the libraries. Anyone who has the proper development environment set up -- one that works across many projects -- should be able to clone the repository and do a build simply by running the build program with no special arguments. There should be no need to edit or install anything into the project space for the initial build.
