Plugin Help Bukkit and Spigot

I wrote this bukkit plugin for my client and he uses a spigot server and it doesn't work. Does bukkit plugins work on spigot servers? I have everything up to date.

 

@Rockinredross867 Bukkit plugin certainly should work on Spigot servers. Please put the latest.log (found in the logs folder) in a pastebin.

 

This is all he gave me

@Rockinredross867 You are compiling with a higher version of Java than the server is running.

 

Thank YOU

 

@Rockinredross867 No problem! Always glad to help!
