For what? Its on the newest version.
When I use server start to fire up my minecraft server. I mean it works to create all the files, but not to play. I did find away around this though. You save a file called RUN.bat with the following contents:
@ECHO OFF
SET BINDIR=%~dp0
CD /D "%BINDIR%"
"%ProgramFiles(x86)%\Java\jre6\bin\java.exe" -Xincgc -Xmx1G -jar craftbukkit-0.0.1-SNAPSHOT.jar
PAUSE
-and if you get an error with that, take away the "(x86)"
Then that will execute the bukkit snapshot and create all the folders+when you run it again, it will act as your server.
