What is MassiveCore?
MassiveCore is a Bukkit plugin that contains components the MassiveCraft developers use for developing other Bukkit plugins:
- ItemStack and Inventory serialization
- Commands
- Plugin Integration
- Data storage with JSON
- Disc IO
- … and much more …
Install
- Stop your server.
- Put MassiveCore.jar in your plugins folder.
- Start your server again.
Plugins Using MassiveCore
Internet Connections
MassiveCore sends anonymous usage statistics to bstats.org when your server starts and downloads the latest sponsor configuration file from massivecraft.com hourly. You can disable these internet connections by setting "metricsEnabled" and "sponsorEnabled" to false at the very bottom of the main configuration file.

Do you have a Mac? If you do, I think that's the problem. I also have an IMac and Java 7.

Posted Feb 15, 2014Yes, at last, Mcore, factions, vampires and the creative gates plugin are finally all compatible with perworldplugins, well for me that is, I just used the craftbukkit or spigot build that came out on December 31st and everything was working! (1.7.2 R02)

You can't just say "It does not work". That provides zero information. You must show the error messages and provide a document with loads of detailed information about your server, such as software versions.

Posted Feb 14, 2014Will the factions and vampire plugins have a 1.7.2 R0.3 Version? Because I cannot get them to run in 1.7.2 without using an old version.
The new MCore version didn't fix them, either.

Posted Feb 14, 2014MCore isn't compatible on my server, as it was the cause of stopping my server. Any chance you guys are updating this?
