To build the .jar file, you will need maven. Also, the CrackShot library is in no public repository, so please create a directory called `lib` and put the latest CrackShot.jar file [(available here)](https://www.spigotmc.org/resources/crackshot-guns.48301/) inside it. Now you can do `mvn install`
ChestSort takes an instance of org.bukkit.inventory.Inventory and copies the contents. The resulting array is sorted by rules defined in the config.yml. This takes far less than one millisecond for a whole chest. So there should be no problems even on big servers, where hundreds of players are using chests at the same time.
