[1.12] Get any potion registered

[_Bedrockbreaker_]

How can I get ANY potion registered from "vanilla" minecraft and other mods? I have a food, that applies all the normal ones by generating a random integer from 1 to 28, but if I want it to do the ones from mods, how can I get those? side question: how can I install other mods in my development? like jei, any other mod... side-side question: how could I get any item/block/whatever I want registered to use for diabolical uses?

For iterating through potions, just find the registry object for potions and iterate on it. GameRegistry should hold the registry instance. (There could be one in Potion class as well) 

To use the mods on dev env: download deobfuscated version, and add that in the mods folder in the run directory (I'm not sure with this one: for now putting normal mod could work). You can also specify some kind of (optional) dependency with gradle.

 

Also just in case: there are @ObjectHolder which allows access to the registered instances even from other mods.

The Vanilla and Forge registries are stored in the ForgeRegistries class.

I think you mean @ObjectHolder.
