Don't just block certain recipes, actually remove vanilla recipes from your server with RecipeRemover!

If you're having trouble, please enable debug in the config and get a fresh server start log before reporting.
Either I'm blind or I'm surprised a proper plugin for this doesn't exist. This is useful to use in conjunction with plugins like CustomItemRecipes when you want to override vanilla recipes.
For right now, only a simple config option exists (along with a debug boolean):
vanillaResultsToRemove:
- HOPPER
This list should contain the list of Material recipe results you wish to remove from the server. A list of valid Material enums can be found here: https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/Material.html
Please do note that removing some recipes that are related to advancements may cause errors and warnings when worlds are loaded/players join. I'm not sure how it affects advancements (other than obviously removing the possibility of obtaining the advancement for the involved recipe), and it may cause other issues with more complex recipes such as dyed leather armor and banner crafting. It seems everything else is okay from the minimal testing I've done, and the plugins/worlds load despite the errors, so yea, just keep that in mind. If you're curious as to what's going on, enable debug in the config.
RecipeRemover must either be loaded on server start or when no players exist on the server, else it will refuse to attempt removal of recipes (doing so will corrupt the session of any logged in player, resulting in the server being unable to save anything they've done for that session.)
