Separate Forge and NeoForge

[trainb0y]

For context, I'm trying to port a mod that uses YACL to NeoForge, but it's incompatible, since NeoForge made breaking changes.

Loosely following this migration guide I tried to add NeoForge to YACL. I'm not even sure if you're interested in supporting NeoForge or want the maintenance burden, but I had some free time so I figured I might as well give it a shot, rather than just opening a feature request issue.

Some Questions/Concerns/Notes/Stuff

• Moved to Architectury Loom 1.4 beta for NeoForge support. I don't know if it broke anything.
• I removed the Vineflower gradle plugin, as gradle was complaining that it was already added. (Loom 1.4 added vineflower support). I'm not sure if Vineflower is actually being used now though.
• There is a lot of duplicated stuff, in both the gradle files and the forge mod toml. The only code changes I made to NeoForge were fixing the imports, since NeoForge repackaged everything. There's probably a good way to share more code, however I'm not qualified to do it lol.
• The mods.toml files are slightly different, as NeoForge wants mixins to be specified in it, and their FML version seems to have been reset to 1. However, judging by the rest of the project, having hardcoded values (like that 1) in places like that is discouraged. Not really sure what to do about it.
• Forge and NeoForge were both printing a warning about the mixin config not specifying minVersion so I added it. Was this intentional? Is there a reason not to specify it?
• Might have broken the access wideners. Not sure. I've never tried to use them before. (edit: works now)
• Neither test-forge or test-neoforge seem to work. Running the dev environment fails to load (here's a log fragment, the full log is too long to upload due to ModelBakery warnings). I didn't really touch much of the existing Forge stuff, so I'm not sure why it isn't working. Maybe I'm just doing the wrong thing? I'm very new to Architectury and haven't really touched Forge before, so it might just be user error.
• Running remapJar on both test-forge and test-neoforge seems to output jars that don't include test-common and therefore won't run. Since I couldn't get either of them to run using gradle, I wasn't able to actually get the NeoForge version to load, and I have no idea if it actually, um, works.

So yeah, this is definitely not ready but I figured I should open a PR to see if I'm at least heading in the right direction, before sinking any more time into it.

Since I couldn't get the testmod to load I decided to try with my own mod, and yeah, it crashes, and im fairly sure its an access widener issue. I'll see if I can fix it, but I don't really know what I'm doing when it comes to loom and gradle nonsense, if that wasn't obvious already lol.

Seems to work now

Would it not be better to drop Forge support and just support NeoForge for 1.20.2+, I don't see why anyone would bother supporting Forge anymore?

For now I think it best to continue to support MinecraftForge, purely because I'm not really privy to the state of the forge community at the moment. If it is clear that old MinecraftForge is dead, it's trivial to remove it.

Can't get this to run in a clone. Can't merge until it launches lol.

Ignoring NeoForge for a moment, I tried to run the MinecraftForge testmod, but couldn't get that to launch, even in a fresh clone. This feels like user error, and I don't really know what to do at this point.

Recorded a bunch of logs, maybe you can tell what's going on here?

test-forge on 1.20.x/dev branch, with no changes

No idea why this one doesn't work.

test-forge on 1.20.x/dev branch with loom 1.4

I don't have the beginning of the log for this one because the modelbakery errors are so long, I can go and grab it if its helpful, but I'm lazy.

test-forge on my pr

Almost identical to the loom 1.4, which makes sense since I didn't touch much of the MinecraftForge stuff.
By these I assume the issue is loom 1.4 and not my pr specifically?

test-neoforge on my pr

Seems to be the same issue, just minus the modelbakery spam?

Conclusion

I really don't know at this point, I'm kind of stumped. Some of this just feels like user error. Like I said, I haven't really touched Forge or Architectury before so maybe this is obvious to someone more experienced. I'm basically out of ideas though.

I found it.
Says something like "failed to find mod metadata for mod ids specified in @Mod entrypoint"
