This isn't a bug as it's in my own code.
As a project to challenge myself with, I'm creating a custom Minecraft launcher. In short, when I am using forge, of course I need to download the libraries. I am aware the general format is \<package\>:\<name\>:\<version\> and the name of the library is just the name '-' version '.jar' appended to the above, replacing dots in the package name appended to "https://libraries.minecraft.net/ or for some forge libraries, "http://files.minecraftforge.net/maven/.
This code works. It downloads all the libraries for the vanilla game, and all but two for forge: com.typesafe.akka.akka_actor and com.typesafe.config. When attempting to download those adhering to the same format, I get a 404 error. Is there something I'm missing? The game launches, but I have not done much testing within it. Additionally, I know that the topmost library listed in the libraries list (or array in java I guess) uses the forge universal file itself located in /net/minecraftforge/forge/\<some version id\>/forge-\<version id\>.jar so I could only imagine the other two missing libraries must be installed in this way. Is this right? Thank you!
