uSkyBlock
This DevBukkit page is being updated again with current releases and links to the maintained uSkyBlock project. We had lost access to the DevBukkit project page for some time, but have now regained it and are bringing it back up to date.
uSkyBlock is an open-source Skyblock plugin for Paper and Spigot.
Start on a small floating island, build it into something thriving, complete challenges, and team up with other players to push your island further.

Why uSkyBlock
uSkyBlock gives you a complete Skyblock foundation with island progression, deep customization, and a maintained open-source codebase you can build on long term.
Complete Skyblock gameplay. Build your server around islands, progression, challenges, and party play.
Deep customization. Shape the experience with focused configuration including challenge design, biome options, custom islands, and more.
Integrates with your server. Extend uSkyBlock through its public API and placeholder support so it fits cleanly into your server.
Open source with proven lineage. uSkyBlock is fully open source under GPLv3, free to run, and backed by more than a decade of project history.

Posted Feb 1, 2015Hi, it's me again :D
After some testing, WolrdGuard 6.0 (beta 5) prevent non-members to hit mobs !
But now, it doesn't require any flags to have a protection, just the region is enought to protect breaking blocs, chests, doors, etc..

The Spigot hack is basicly a 1.7.9/10 server so use the version for that.
@FabioZumbi12
If you wnat to use the WG5.9 your best bet is to use the 1.7.9/10 version.

Sorry to bother you so much, but Vault 1.5.x (which is required by uSkylock 1.8) isn't compatible with 1.7.10 server..
But, I didn't understand one thing, why don't you update uSkyblock 1.7 to WG 6.0 ?

Reg. WG 6 vs WG 5.9 - the WG default flag handling has changed quite a bit between the two - so, the two versions (1.7.9/WG5) and (1.8/WG6) has different code, even though WG 6 can run on a 1.7.9.
If you have WG6, and are running 1.7.9 - odds are, you will be able to use the 1.8 version of uSkyBlock - though - test the region-stuff, and keep an eye on your server-log.
