Since 1.8, minecraft to use of new id alpha ("minecaft:stone") for example. However, the API always uses ID and not two what is it's a pity because since 1.10 (or 1.9) we are obliged to use / give @p minecraft:stone instead of / give @p 1. It would be necessary to add a method which allows to get back a Material from newer ID even if it is possible with the NMS with MinecraftKey.

Ex: Material m = Material.findByMinecraftId("minecraft:stone");
