Who said you have to mine to get blocks? Anyway, this datapack will allow you to play almost without a pickaxe: you want to get a block? Look at it and it will appear in your inventory magically!

Note: The datapack doesn't work with bedrock blocks, ender portals and 2 or 3 other things like that. (This is voluntary)

This is the person who created the plugin: []

I just uploaded it to SpigotMC
