Ant/MinimalJarSample

You can get the <pack> task here: http://sadun-util.sourceforge.net/pack.html

You can get yguard, a free obfuscator, here: http://www.yworks.com/en/products_yguard_about.htm

Using both will shrink your Jar file by quite a bit. Even if you're including source code with your bot, obfuscating your robot will make your .class files much smaller. The only downside is that if your robot throws an exception, the stack traces are giberish, like NullPointerException in class davidalves/A/B/A.class (unknown source)
