Not finding the main class in craftbukkit

I just got the newest release (as of about 1:20 PST, I can't find where to find the exact build # of it) of craftbukkit and tried to run it, but I get this error:

C:\Users\<myusername>\AppData\Roaming\.minecraft\Bukkit 2>java -Xms2048M -Xmx2048M -j
ar craftbukkit-0.0.1-SNAPSHOT.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/bukkit/craftbukki

Could not find the main class: org.bukkit.craftbukkit.Main. Program will exit.

It works fine when I try to use the older build I had (again, dont know the number, but I think I downloaded it some time yesterday). Any ideas?

 

I'm seeing the same thing with build 112.

EDIT: build 114 seems to be working fine.

 

Yup, the new ones working for me too, now. How do I find out what build I have?
