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 Dec 12, 2013Sorry for being such a noob...but I thought I'll give CreativeGates a try on my hosted small server and so I wanted to install Mcore. I tried the latest version (7.x) and have the latest dev build of bukkit installed.
The install on server restart didn't work though - in the log I found this:
[17:36:25] [Server thread/INFO]: This server is running CraftBukkit version git-Bukkit-1.6.4-R2.0-38-g4b4e2cc-b2953jnks (MC: 1.7.2) (Implementing API version 1.7.2-R0.1-SNAPSHOT) [17:36:26] [Server thread/ERROR]: Could not load 'plugins/mcore.jar' in folder 'plugins' org.bukkit.plugin.InvalidPluginException: java.lang.UnsupportedClassVersionError: com/massivecraft/mcore/MCore : Unsupported major.minor version 51.0 at org.bukkit.plugin.java.JavaPluginLoader.loadPlugin(JavaPluginLoader.java:184) [craftbukkit.jar:git-Bukkit-1.6.4-R2.0-38-g4b4e2cc-b2953jnks] at org.bukkit.plugin.SimplePluginManager.loadPlugin(SimplePluginManager.java:305) [craftbukkit.jar:git-Bukkit-1.6.4-R2.0-38-g4b4e2cc-b2953jnks] at org.bukkit.plugin.SimplePluginManager.loadPlugins(SimplePluginManager.java:230) [craftbukkit.jar:git-Bukkit-1.6.4-R2.0-38-g4b4e2cc-b2953jnks] at org.bukkit.craftbukkit.v1_7_R1.CraftServer.loadPlugins(CraftServer.java:255) [craftbukkit.jar:git-Bukkit-1.6.4-R2.0-38-g4b4e2cc-b2953jnks] at org.bukkit.craftbukkit.v1_7_R1.CraftServer.<init>(CraftServer.java:233) [craftbukkit.jar:git-Bukkit-1.6.4-R2.0-38-g4b4e2cc-b2953jnks] at net.minecraft.server.v1_7_R1.PlayerList.<init>(PlayerList.java:63) [craftbukkit.jar:git-Bukkit-1.6.4-R2.0-38-g4b4e2cc-b2953jnks] at net.minecraft.server.v1_7_R1.DedicatedPlayerList.<init>(SourceFile:14) [craftbukkit.jar:git-Bukkit-1.6.4-R2.0-38-g4b4e2cc-b2953jnks] at net.minecraft.server.v1_7_R1.DedicatedServer.init(DedicatedServer.java:126) [craftbukkit.jar:git-Bukkit-1.6.4-R2.0-38-g4b4e2cc-b2953jnks] at net.minecraft.server.v1_7_R1.MinecraftServer.run(MinecraftServer.java:420) [craftbukkit.jar:git-Bukkit-1.6.4-R2.0-38-g4b4e2cc-b2953jnks] at net.minecraft.server.v1_7_R1.ThreadServerApplication.run(SourceFile:617) [craftbukkit.jar:git-Bukkit-1.6.4-R2.0-38-g4b4e2cc-b2953jnks] Caused by: java.lang.UnsupportedClassVersionError: com/massivecraft/mcore/MCore : Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) [?:1.6.0_27] at java.lang.ClassLoader.defineClass(ClassLoader.java:634) [?:1.6.0_27] at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) [?:1.6.0_27] at java.net.URLClassLoader.defineClass(URLClassLoader.java:277) [?:1.6.0_27] at java.net.URLClassLoader.access$000(URLClassLoader.java:73) [?:1.6.0_27] at java.net.URLClassLoader$1.run(URLClassLoader.java:212) [?:1.6.0_27] at java.security.AccessController.doPrivileged(Native Method) [?:1.6.0_27] at java.net.URLClassLoader.findClass(URLClassLoader.java:205) [?:1.6.0_27] at org.bukkit.plugin.java.PluginClassLoader.findClass0(PluginClassLoader.java:80) [craftbukkit.jar:git-Bukkit-1.6.4-R2.0-38-g4b4e2cc-b2953jnks] at org.bukkit.plugin.java.PluginClassLoader.findClass(PluginClassLoader.java:53) [craftbukkit.jar:git-Bukkit-1.6.4-R2.0-38-g4b4e2cc-b2953jnks] at java.lang.ClassLoader.loadClass(ClassLoader.java:321) [?:1.6.0_27] at java.lang.ClassLoader.loadClass(ClassLoader.java:266) [?:1.6.0_27] at java.lang.Class.forName0(Native Method) [?:1.6.0_27] at java.lang.Class.forName(Class.java:266) [?:1.6.0_27] at org.bukkit.plugin.java.JavaPluginLoader.loadPlugin(JavaPluginLoader.java:173) [craftbukkit.jar:git-Bukkit-1.6.4-R2.0-38-g4b4e2cc-b2953jnks] ... 9 more

This... This can't be stressed enough. When server owners are starved for an update of particular plugin, it is the perfect opportunity for the unscrupulous. All they need to do is get the bleeding edge repo source, insert a trojan (say, send playernames, command messages and other identifiable info (authme/xauth etc) to a listening server) and post it for anyone foolish to grab and install it.
TL;DR: Don't want to compile it yourself? Wait for an official build, or run the risk of getting seriously screwed.

Bukkit Dev staff look through the class files to make sure there isn't anything fishy going on, and with 1.7.2 changing servers a lot, they had to change mcore a lot, so more new code for the Dev staff to look through

Posted Dec 11, 2013You guys are crazy to be downloading someone else's unapproved build.
Learn to do it yourself or deal with the potential risk that someone has implemented a backdoor into the jar that you are carelessly downloading and using on your server.
There is a reason unapproved builds are deleted. It's for your safety.

Posted Dec 11, 2013Mcore is updated, just have to know how to find it ;). But I have a question, I started my server with Mcore and Factions, I'm looking through my plugins folder and all I see is the mcore folder I don't see a Mstore folder at all, it's not in /plugins or /mcore. Any ideas?
Edit: Nevermind got it to work.

I cannot find the more 7.0.X either. On the faction bukkit page, it says make sure to update to the latest mcore 7.0.X so i thought it was out.
nvm. just found it and edited this message.

Posted Dec 11, 2013If your gonna jump up and down about the 7.0 being on github, then at-least point a link directly to the JAR for us. I downloaded everything there, and still no .Jar to be found.

Posted Dec 11, 2013There is NO mcore 7.0 .jar file on the github site... Could someone PLEASE send it to me if it is there?
Why did Factions and Vampire update to support 1.7.2 if the mcore isn't even available yet.. or is it?
