How do i make an inventory go into config

I need some help with my plugin: StarCache
Currently you have to add items into the config, so it will make different crates fall. Well currently you have to add them into the config, how could i make it so you can just type a command i'll make "/starcache input" and it'll add all the items in your inventory as a new crate
Config:

Code (Text):

general:
##################################################
# Time Between each Star Cache Event. #
# Expressed in Seconds #
##################################################
eventCooldown: 43200
##################################################
# Radius is caclulated in a square #
# Values will be +- the defined #
##################################################
world:
radius: 5000
##################################################
# DO NOT TOUCH #
##################################################
lastEvent: 0
##################################################
# Are we using Factions to determine #
# safe areas? #
##################################################
useFactions: true
##################################################
# How should we broadcast coordinates? #
# By CHUNK or EXACT? #
##################################################
announcer:
method: CHUNK
caches:
netherstar:
- 399%1
blocks:
- 57%32
- 41%32
- 42%32

the end where it says "caches:" is where i want to add the command so i can input items into the starcache, i've never worked with something like this in a plugin so some help would be nice!
If someone is confused on what i mean just message me and i'll try to explain better
Here is the caches part in my config.class

Code (Text):

        if (config.contains("caches")) {
            Set<String> caches = config.getConfigurationSection("caches").getKeys(false);
            for (String cache : caches) {
                System.out.println(cache);
                List<String> items = config.getStringList("caches." + cache);
                cacheList.add(new Cache(items));
            }
        }
    }

So for the netherstar cache it would be caches.netherstar
So to add my inventory it'll just take my inventory and add a
caches.[name] then input inventory into the config then i can reload the config
Also i've been messing with it, how could i add an item with an enchantment? considering 311%1
would be 1 diamond chestplate how could i add an enchantment? i've been searching around and
can't get this to work

 

How exactly would i do this?

 

This will not work for my config... but thanks for the help

 

That puts a players inventory in it's own config and in a different format, see that's why i'm having issues i don't want to have to redo my whole config, see how mine is the id%amount

How would i put this into a command like this "/starcache cache [name]" To put it as:
caches:
[name]
[item]%[amount]
