Does anyone have a list, or even better a target that normalizes, the environment variables that are common on Linux, Windows, and OSX that would enable cross-platform, consistent Apache Ant builds? For example: On OSX, you can specify env.HOME and perform file operations, like loading a property file, from the user's home directory, /Users/michaelprescott. On Windows, env.HOME isn't available. Instead, you have to specify env.HOMEDRIVE env.HOMEPATH .

A lot of that is built into Java. Definitely check out user.dir and similar from System.getProperties() which Ant will use.
Here's a list of some of the more interesting ones:
- file.encoding = MacRoman
- file.separator = /
- java.class.path = ./
- java.class.version = 50.0
- java.endorsed.dirs = /System/Library/Frameworks/JavaVM.fram...
- java.ext.dirs = /Library/Java/Extensions:/System/Library/Ja...
- java.home = /System/Library/Frameworks/JavaVM.framework/Ver...
- java.io.tmpdir = /var/folders/Kp/KpmOujsB2RWdqE+BYnAOX++++T...
- java.library.path = .:/Library/Java/Extensions:/System/Libr...
- java.specification.version = 1.6
- java.vendor = Apple Inc.
- java.version = 1.6.0_20
- line.separator =
- os.arch = x86_64
- os.name = Mac OS X
- os.version = 10.6.3
- path.separator = :
- user.country = US
- user.dir = /private/tmp/properties-test
- user.home = /Users/dblevins
- user.language = en
- user.name = dblevins
- user.timezone =

Thanks! Those are good enough for me and consistent across the platforms I tested. It is curious that the Apache Ant documented method of using environment properties is inconsistent, whilst these are consistent. This is the first time I've seen that java makes them available. So, I could write a little java app that prints the results of System.getProperties() and see all the properties made available through file., java., path., and user.?

You can always run:
$ ant -diagnostics
It will spew a lot of information, that you are looking for, to your console.
