Eclipse + Proguard + Ant

Question

Ok... I'm overwhelmed. I'm putting my game in a jar for webstard, and obfuscating it with Proguard. I use Eclipse, and I know it has Ant integrated, and I'm pretty sure it can help me here. Right now I save (Eclipse auto-compiles), I run Proguard to obfuscate my code, then I manually create a Jar file by renaming a .zip file I make with WinRAR, and move in the particular folders of obfuscated code I want. That's really tedious and time consuming to have to do that every time I make some changes to my code.
Now... in looking up information on Ant, I feel like I'm looking at a whole new language. Even beginner's tutorials seem to make no sense. Maybe I'm just looking too hard to find a specific solution, but I don't want to just jump out into the ocean of Google with no sense of direction. Could anyone help me out with what I need to do, or give me some good resources/direction to head for so I'm not completely clueless as I learn how to work with this? Thanks!

Ant is fairly simple. I'm sure they have a sample app build script somewhere, and I recomend you spend some time looking over the tutorials, and asking sperifc questions (either here, or might be better at [url http://forum.java.sun.com/forum.jsp?forum=54]n2j or even the [url http://ant.apache.org/mail.html]Ant User Mailing List.
But a basic Ant file looks like:
file system:
|
+- src (containing the source code)
+- misc (Containg the mainifest)
+- res (Containg the resouce files)
You might have to change the above, to match however Eclipse works
<project name="PLACE YOUR NAME HERE" default="dist">
