When converting .zip files into .jar files by renaming them they always corrupt. I'm downloading the source code for a Minecraft mod and editing some of the .json files in it nothing much but when I change the . suffix from zip to jar the mod does not show up. Does anyone know a better way to convert a zip file of source code into a .jar?
Im not very experienced with these things as I just started playing Minecraft and wanted to make a cool mod for me and my friends.
