I'm trying to recode one of my mods which was written in 1.6.4, and part of that includes reinstalling the old environment because I had stepped away from modding for a bit. But... downloading the latest 1.6.4 and running the install script results in a failed install because the digest of minecraft_server.jar does not match what is expected.

 

This isn't an attempt to mod for 1.6.4, this is an attempt to go from a known state to a new one, testing included, so for that I like to have a working base to start with.

 

Does anyone have any advice on how to proceed?

I would recommend just going straight to 1.7.2, as alot of things have changed and it will be even more confusing if you get used to 1.6.4 again. Most 1.6.4 tutorials have details on how to update that code to 1.7.2, so it really doesn't end up being that forign

It's not a matter of being confusing or getting used to a version... I program in at least 3 different languages at work alone. Not just library versions, full language differences and somehow I'm expected to make them all work together.

 

Keeping version's straight isn't a problem.

 

Yes, 1.7.2 is the end goal, but I have to know what I'm starting with first, and that includes using the old environment to generate the encrypted data files that need to be readable in both 1.6.4 and 1.7.2. And the only way to test that is to actually make said files with known data.

 

You do not need anything more than the forge download to begin in 1.7.2. There is even a dummy mod example to make sure you don't screw any important stuff while setting things down.

You should start with that, then getting the same environment in 1.6.4 will be a piece of cake. (using build 964, of course)

it's a recode, not a restart. I'm not rebuilding this thing from scratch... though there will be significant portions changed.

 

As it is, the whole issue might be a moot point because the guy whose's asking me to do the work changed his mind and said he doesn't need the old data files ported over now, they're willing to start from scratch.

 

I'm just going to tell him 'good, wasn't going to happen anyways'.
