This software is a wrapper for Minecraft that mirrors the game chat to a XMPP Multi-User Chat. It was born out of the necessity to link a 1.8 server with a chat server when both Bukkit and Forge hadn't updated yet. It captures the log from the standard output and injects command to the standard input, thus doesn't actively rely on Minecraft's implementation and potentially works with older and future versions (that's completely untested).
To build the software, you need thge Smack library (recommended version: 4.0.4) The software actually use some of Apache's and Google's libraries but they're included with Minecraft.
There are several ways to install the compiled classes. You can either pack the .class files within minecraft-server.jar (with Smack too), if you make sure to replace the manifest with XMPPCraft's, or you can pack them into their own jar or even not at all, the most important is that Minecraft's and Smack's classes are in the classpath upon launch.
Before launching it for the first time, you'll need to set a few settings. XMPPCraft uses three .json files: users.json, language.json and settings.json. You only have to take care of the latter, as the two others will be created and populated automatically. Number of settings used by the software have a default value (such has the port), which will be written into the JSON file when the software encounters them for the first time. A default settings.json file is included at the root of the project, with fields you need to set tagged "REPLACE". They are pretty self-explanatory.
language.json contains (most of) the text the bot will answer with. Having named my own instance of the bot "GLaDOS", those are personalized accordingly. You can change them in the language.json file, or directly in the source code. But be aware that the source code's version is a default value, that will be ignored if language.json has one.
As specified in the COPYING file, this project is licenced under the WTF public licence, so you can pretty much do whatever with the source code. Of course I'd appreciate a heads up and credits if you modify/fork/redistribute this code, but that's up to you.
