Using Hudson environment variables to identify your builds | Java.net

So your CI server now automatically deploys your application to an integration server. You've even configured it so that you can manually deploy to the QA server using the same process. Great! But wouldn't it be nice to know exactly what build you are looking at at any point in time? Well, Hudson lets you do just that.
When Hudson runs a build, it passes in a few useful environment variables, that you can use in your build script. This is a great way to inject information about the build into your deployable application. For example, Hudson build has a unique number, which you can reference in your build scripts using something like "${BUILD_NUMBER}". This is the list of variables (taken from an obscure corner of the Hudson documentation :-)
