@Onur_Korkmaz As our friend above already said… bukkit/spigot plugins won’t work on Sponge.
However some (very very few) plugins are universal and they may work on both platforms. I actually did find some.
There is also a thing called Pore which I tried myself too. It helps using plugins which are made for Bukkit/Spigot on Sponge. Many plugins may not work but you can still try it!
