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 6, 2016@XxthedarkkingxX Why wouldn't you want Spigot or PaperSpigot? That sounds a bit dumb.

If you are still encountering this problem go to the mstore/massivecore_conf/instance.json file. Then change "usingRecipientChatEvent" to false.

Update to Spigot, or update Spigot.
@SirFaizdat
http://www.massivecraft.com/massivecore
@Glitchblade
Always use the latest available version of Spigot as that is what Factions is built against. Dev Bukkit does not let you select the latest version.
@CheesyGamingFTW
We don't support older versions of MassiveCore and Factions, please update.
@LardPerk
You have edited the mplayer data file in mstore, please undo whatever changes you have done to it. Always backup configuration files and databases before manually editing them.
@LouisSphinx
This is from Factions. You can find the configuration outline here: http://www.massivecraft.com/factions-configure
Set chatSetFormat to false
@obsidiancraftfactions
Your server provider has restrictions on the size of files you can upload it, you should contact your provider. If you installed multicraft you can ask them how to raise this limit (http://www.multicraft.org/site/contact)

Posted Sep 20, 2015Can I have the source for factions 2.6 (1.7 only) and the source for massivecore 7.3 (1.7 only) I want to update it to 1.8 because factions 2.6 is better than 2.7 IMO. My players find it easier to use. My server is 1.8 only though.
