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.

It seems you have used the 1.7.9 version on a 1.7.2 version. As you have CraftBukkit 1.7.2 R0.3 you need to download the correct version which is http://dev.bukkit.org/bukkit-plugins/mcore/files/31-mcore-7-0-2/

Posted Jun 26, 2014A lot of errors I have received with Massive Core came from using Bukkit's latest Beta build (1.7.9-R0.2)
Try using the previous beta and see if you have better results.

Posted Jun 23, 2014@thedark1337 Latest version should work on 1.7.9. However, to fix "ambiguous", just cast parameter to double. Are you sure you're using GitHub source code?

Posted Jun 21, 2014Hi I was able to get Factions and Mcore to work but I have a chat issue where whenever one person says something, it is repeated in chat. I can't use the /c command because it conflicts with another plugin. Is there a way I can disable the repeats? That would make my day.
