1.17.1 Minecraft Jar Folder
I am trying to find the (version).jar folder for 1.17.1 but it is not there, all that is there is a .json file. Does anyone know where it is?
If there's only the JSON file, it means the .jar hasn't been downloaded yet. You must launch 1.17.1 from the launcher at least once - at that point the launcher will download the .jar from Mojang's servers before starting the game.
