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.
Official Server

Join in and play with us on the official Factions RPG Minecraft Server!

You have corrupted files, look and see if any of the files are corrupted in your mstore folder, that includes all user and config folders, this happened to me before, when the plugin stopped unexpectedly during a power cut.

Posted Sep 11, 2013MCore is blowing up reading a file while trying to load as a part of factions load. However MCore does not say which one of hundreds of files it is choking on. Is there a way to enable that?

Posted Sep 10, 2013@muzixxx As stated clearly in the installation instructions This plugin requires Java 7.
Your version of Java is outdated. Update to at least Java 7. Do you already have Java 7? Then perhaps you have Java 6 installed as well and for some reason the Java 6 is used when launching the minecraft server. Uninstall Java 6.

Posted Sep 6, 2013@cayorion , do you have any idea how this could be fixed? (chat below) it refuses to work. none of my plugins are interfering with this plugin, of course, I took the precaution and made sure they would not. but it still did not work, this was the first plugin I installed
