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.
Maintained for modern servers. Continues to evolve for current Paper and Spigot versions, with new features, docs, support, and maintenance.
International by default. Support international player communities with bundled translations into 53 languages.

Posted May 20, 2017Is there something in the config somewhere allowing the island level to calculating items placed within containers on the island? Rather than just blocked placed within that area?
If not would be great allowing that since a player wouldn't need to make massive towers of materials

Posted Apr 4, 2017I have decided to leave the Bukkit/Spigot community and therefore I will no longer give support for any plugin.
It was fun for the last 6 years.

Posted Mar 25, 2017Just to let you know, I got this message again:
Island 640,640 has unknown member-section 5d0e047e-37aa-4185-b0d7-93ac8505cdce
And I told you it was because of VoidSpawn. Well it's not
I stopped the server for a second because I downloaded a map I wanted to see. I then removed my old world and placed a new world in there. I started the server and the message appeared. I then deleted the new world and placed back the old world and everything was good again!
So if anyone asks how come that message appears, you might know now.

Posted Feb 23, 2017And again, I got the "invalid-member section" and I fixed it, caused by a plugin called VoidSpawn. Removed the plugin, started the server and the message didn't appear anymore. Thank god, but it's still very strange it is having issues now because I have used it for a few months.

Posted Feb 24, 2017I never used VoidSpawn as that is were the bedrock block is for to prevent falling in the void.
Also VoidSpawn doesn't list uSkyblock for support if you look into his discription page.

Posted Feb 19, 2017When restarted did you remove the whole folder? Looks like the "lastIslandConfig.yml" was still present.
If this was not the case you might want to check in the config if:
playerdb: # valid values are: yml, memory storage: memorySet it to YML and restart the server. This hopefully clears the memory form the last setting (not 100% sure).

Posted Feb 19, 2017I think this person is bugged (Jarvic)
Because I used 4 other alts that created an island, all good cords (Like 0 320, 0 -320, 320 320)
And I then do /usb island delete jarvic and re-create an island, keep having -2560
maybe this can help Link Removed: http://www.mediafire.com/file/6suhwl24a35plak/usb.rar

Posted Feb 19, 2017clear the "orphan.yml" and delete the island location (-2560,1600) file and you should be good again.
Because Jarvic's file is still present in the island folder it will keep creating his island on that location.
Still many weird things seems to happen on your with USB which I cant explain.
