fr.neatmonster.ncpplugin has dependencies on many different versions of CraftBukkit. Maven tried to pull all of them in for a build and failed when it couldn't find them all. I've excluded it since it's not actually necessary to build.
When I was adding the exclusion, I noticed that you depend on both spigot-api and bukkit. This is redundant so I removed spigot-api. The plugin still builds but now has far fewer dependencies.
