Minecraft Forums

Whenever I add a class/delete meta-inf/ or modify ANYTHING in 1.7.10.jar it just redownloads everything, I'm trying to make a custom survival client and I cannot achieve anything with this problem, also whenever there's something modified it just says Downloading 1.7.10.jar from minecraft version database, I need help ASAP

EXAMPLE : I modify the main menu, replicate this class to the game file, I launch the game from the launcher and it resets to the original 1.7.10, the file size, classes and everything resets

Tried making a version named Test with the json named test aswell.

MC reverts back to it's original files with no modified classes at all

Bump

It's not logs, it's whenever I modify the jar file it downloads itself again and overrides the one I've modified for some reason, it has to do something with .json files?

It sounds like you are renaming the json file but are not changing the "id" line inside it, which tells the launcher which version it is for. You can find all the steps required to make a separate modded version here:

http://minecraft.gamepedia.com/Mods/Installing_mods#Installation_for_the_1.6.2B_launcher

Note: they say you can just rename the extension to zip so you can extract/re-zip it without a 3rd party utility but sometimes there are classes with invalid Windows file names (e.g. aux.class, which is present in at least 1.5.2 and 1.6.4 but not 1.7.10; I had to use WinRar as even 7Zip wouldn't let me just add the classes to the jar.
