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 Apr 2, 2014Is there a Bukkit 1.7.5 compatible version of mcore on it's way? Right now 1.7.2.R0.4 (#3024) is the latest you can use without mcore and factions failing.
