I would very much love to see ServerCore ported to Forge 1.18.2. I can see you've started on a 1.19.x beta, which is awesome but a large number of 1.18.2 modpacks are popular right now and this could really help me out with some performance tuning. I used this mod previously on Fabric (1.18.2) and it was fantastic.

Please don't make me beg!

Any version of the forge loader under 1.19.1 causes me a lot of trouble with servercore's dependencies and a dozen other badly explained random errors. I don't really support 1.18 anymore for fabric either, and don't particularly feel like rewriting most of the build scripts and maybe even part of the codebase to (maybe?) hack a 1.18.2 version together that works on forge.

I can backport version 1.3.5 for both forge and fabric to 1.19.3, 1.19.2 and 1.19.1 though.

Sorry to hear that - packs like All The Mods 7 could really use your tool, it'd make a huge difference but I do get it.

In the end I did manage to backport it to 1.18.2 - I ran into some difficult to decipher but (surprisingly) simple to actually fix errors in both dev & prod environment.

They will be on curseforge aswell once they get reviewed.

Sorry for the delay - I got around to testing it, and can't get it to boot. Conflicts with the mixins I think. This was tested against All The Mods 7 (Forge) running on Magma, logfile is here: https://pastebin.com/ym75gJjr

There do seem to be some really weird changes in the local variable table of the target method where servercore is failing to inject, which do not exist in vanilla. Considering there's a bukkit/world variable I'm gonna guess this is Magma related.

If this only happens on Magma, there isn't a lot I can do about it, as it seems to be a hybrid between forge and paper.
A good few patches in servercore will overlap or conflict with those in paper / spigot / bukkit. Paper will also include a good bunch of patches servercore has aswell, so it likely wouldn't really help out too much anyway.
