List of common environment variables for cross-platform, Apache Ant, builds

Does anyone have a list of 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 from the user's home directory, /Users/michaelprescott. O开发者_开发知识库n Windows, env.HOME isn't available. Instead, you have to specify env.HOMEDRIVE or 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 =

You can always run:

$ ant -diagnostics

It will spew a lot of information, that you are looking for, to your console.
