Got a huge crash and wont load

to get rid of the error below -noverify
%java.exe" -Xmx1024M -Xms1024M -noverify -jar server.jar

It's not working. Got Java 8 on my server.
Still it says 0 plugins.

[Server] INFO org.bukkit.plugin.InvalidPluginException: java.lang.ClassFormatError: Duplicate method name&signature in class file com/Tuong/OverCraftCore/Core
