It is currently well known that bukkit has been given a dmca request by Wesley Wolfie, but now that that has happened, we now need to rebuild!
So here is whats happening, the folks over from bukkit are now working on a new modding api, called sponge! currently ‘Sponge will start with Minecraft 1.8, with Vanilla Client Support on Forge.’
Old plugins that were written on bukkit will most likely have to be removed, unless someone finds a way to make them compatible with sponge.
Here is a large extract of what they plan to do.
Our ultimate goal is to create a modding API that is easy to use for owners of small servers for friends and family, owners of large servers, and everyone in between. In addition, we also plan to permit client modding.
- Sponge mods should work across several different Minecraft versions without needing an update from the developer, which means that you don’t have to worry about all your mods breaking between each new major release of Minecraft (1.6, 1.7, 1.8, etc.).
- Sponge will support official interoperability with Forge so you can use both Sponge mods and Forge mods together. We are working directly with the Forge team.
- While Sponge will not be directly supporting Bukkit, community projects have been started that aim to provide complete support for existing Bukkit plugins on top of Sponge

Good Luck to you all
