Having trouble importing some classes

I'm using the instructions at http://wiki.bukkit.org/Programming_A_Plugin. I think I've been doing everything right, but I have a problem with using the line import org.bukkit.Player;. All of the other import lines involving bukkit are working, except this one. Also, this is the same problem in the PlayerListener, and it has a problem importing org.bukkit.Block and org.bukkit.BlockFace. I'm fairly certain I'm using the latest version of Bukkit.jar - has something changed in it that has not changed in these instructions? Thanks for any help!

Oops, just read that some things were changed and not changed in the template that I have. Now I don't get any errors Sorry for the stupid thread.
