So, I gave up on bedrock for now and have started to build a new map in Java 1.14.2 and have found I want a shop again, but this time I would like to do it as custom villager trades to make it look like a real store, but everything I have tried does not work. I tried a custom generator and it does nothing, so I am now at the mercy of someone who might know how to do this. Anyone able to help me figure this out?

EDIT: Ok, I think I may have it figured out. For anyone trying to do this, here is a sample one I made to sell 2 things for emeralds. One is a sword with enchantments, the other is just 10 gunpowder. Also I have him facing a certain way (that was fun to figure out). It seems to work, but if I missed something please let me know.

ex.

/summon villager 32550 53 -4780 {VillagerData:{profession:mason,level:5,type:snow},Invulnerable:1,PersistenceRequired:1,Silent:1,NoAI:1,Rotation:[180f,0f],Offers:{Recipes:[{buy:{id:emerald,Count:10},sell:{id:diamond_sword,Count:1,tag:{Enchantments:[{id:sharpness,lvl:5},{id:knockback,lvl:2},{id:looting,lvl:2},{id:unbreaking,lvl:3}]}},maxUses:9999999},{buy:{id:emerald,Count:5},sell:{id:gunpowder,Count:10},maxUses:9999999}]}}
