Forge support about portablemc

[GoodDay360]

Hey man, I got something for you: https://files.minecraftforge.net/net/minecraftforge/forge/promotions_slim.json.
I found this link a year ago while I try to make a server on Google Cloud. I just realized that in this link there is a way for you to get Forge_Version Id.
So just requests installer like this: "https://maven.minecraftforge.net/net/minecraftforge/forge/{MCVER}-{FORGEVER}/forge-{MCVER}-{FORGEVER}-installer.jar"

That's it! 😎
And also can you make the way forge installed it use mods folder inside the version instead of inside ./minecraft/mods?
#Bring Back the Planned label.

Their discord server should help. For optifine I also get A.P.I from their discord server

@mindstorm38 Big thanks!

forge works, you just need to install forge via the jar on forges website, and run that forge installs version id.

[mindstorm38]

I know that forge works but the point is that forge seems not to provide a web (REST) API that provides these download links. That said, a solution might be to find a non official API or to store (or guess) all links for all versions of forge.

For now, this seems complicated to make this happen. The following screenshot was made from the public channel tech-support on the official Forge discord server.

I've a complementary solution to this problem, I just found another interesting maven file.

It's not that simple 😢

Installer procedures have changed a lot of time in the past, and each of these installers doesn't provide a CLI argument to install the client (quite obvious regarding their choice of not allowing automation of the installation). To fix that, I need to make a small wrapper in Java which will hook itself into the installer and run the right code. And I will need one wrapper for each installation procedure. And old versions used to be loaded by original ModLoader!

Another method would be to read the "install_profile.json" file, but this file has also changed a lot of times over the past, and various "post-processing" calls need to be executed.

For now, I'm working on the Java wrapper.

[mindstorm38]

Update: I finished writing the wrapper, and it currently provides a unified interface to install forge up to Minecraft 1.6 (I haven't tested further). 🎉🎉

[mindstorm38]

Already working for latest versions, I've some issue launching 1.11 and older versions because of some syntax error in generated version metadata files and class not found exceptions.

[mindstorm38]

It's now possible to launch a version from 1.7.10 to 1.18.2! Some modifications were made to the launcher itself because it wasn't implementing rights algorithms for libraries resolution.

[mindstorm38]

First release of this addon is released today! Please test it and give me feedbacks in issues or discussions.

I'm also developing launcher in Rust. As I can see now you dont have any java wrappers. How do you installing it?
I'll be so grateful if you will explain how does it really works. Cause now I'm stuck with forge/neoforge installing.

[mindstorm38]

@Umatriz The forge installation is quite complicated, but I found over time that it's simpler to install it without actually running the Java installer. So in the current state, the launcher parses the JAR and acts depending on what found in it (because there is multiple version of the installer). Everything is implemented in https://github.com/mindstorm38/portablemc/blob/master/portablemc/forge.py
