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.

Posted Jul 13, 2014I was trying to get Factions for my Craftbukkit 1.7.2 server, so I downloaded mcore. But Factions isn't working. I snooped around a bit and found that mcore wasn't doing anything. the .jar file just sat in my plugins folder, not creating any config files or anything when i do /plugins inside the server, the server doesn't list mcore or Factions as running plugins. A reply would be greatly appreciated.

Go get a copy of Spigot from around July 4th and you will be fine. Nothing newer nothing older.

Posted Jul 11, 2014This is Spigots take on the matter, Do you need a error log from startup?
How are we ever supposed to achieve anything useful if plugins insist on hooking into obscure, versioned code. (commit: 0dbeede02389a84da5733894c4c676f0446d0dcf) (detail)
