This plugin adds in recipes for nearly every uncraftable item in minecraft. Some recipes include: Bedrock Bells Barriers Tridents Saddles Horse Armor Spawn Eggs Music Discs And much more!
Now includes a config.yml file which allows server owners to choose which recipe types they want enabled.
This does not include chainmail armor. I have made a separate plugin specifically for chainmail armor that also increases the number of chains given when crafted, to make chainmail more viable as an option between leather and iron armors.
If you would like to get that plugin as well, the link is here: https://www.spigotmc.org/resources/chainmail.81330/
If there is an item you would like to see included in this plugin, please leave a comment or submit a pull request at the source code listed. Recipes can be found by using /recipe in essentials.
