   Okay, I think I understand the issue.
   For the compile classpath java selects the api-classes variant
   Specifically because it wants org.gradle.usage = java-api

   > Task :dependencyInsight
   net.minecraftforge:forge:1.18.2-40.3.12 (selected by rule)
     Variant api-classes:
       | Attribute Name                      | Provided     | Requested    |
       |-------------------------------------|--------------|--------------|
       | net.minecraftforge.mappings.channel | official     |              |
       | net.minecraftforge.mappings.version | 1.18.2       |              |

       | org.gradle.jvm.environment          | standard-jvm | standard-jvm |
       | org.gradle.jvm.version              | 17           | 17           |
       | org.gradle.libraryelements          | jar          | classes      |
       | org.gradle.usage                    | java-api     | java-api     |
   

   We only publish one variant of api-classes with libraries that do not have an OS requirement.

   Now, why is that an issue on 1.18.2 and not on 1.20.1
   Well if you take a look at 1.18.2 their root glfw is different depending on the OS:
   3.2.1 on osx, and 3.2.2 on everything else.

           }
         },

           {

               "name": "osx"
             }
           }
         ]
       },
       {

           }
         },
         "name": "org.lwjgl:lwjgl-glfw:3.2.2",
         "rules": [
           {
             "action": "allow"
           },
           {
             "action": "disallow",
             "os": {
               "name": "osx"
             }
           }
         ]
       },

   Whereas 1.20.1 uses the same glfw version for all OSes, just with the natives different by os.

       {
         "downloads": {
           "artifact": {
             "path": "org/lwjgl/lwjgl-glfw/3.3.1/lwjgl-glfw-3.3.1.jar",
             "sha1": "cbac1b8d30cb4795149c1ef540f912671a8616d0",
             "size": 128801,
             "url": "https://libraries.minecraft.net/org/lwjgl/lwjgl-glfw/3.3.1/lwjgl-glfw-3.3.1.jar"
           }
         },
         "name": "org.lwjgl:lwjgl-glfw:3.3.1"
       },

   So, the 'fix' is to publish OS specific variants and make sure that the dependency requests the OS specific variants.

   When i get some free time i'll look into implementing it unless Jonathing wants to poke it first.
   Main thing is I need to make sure that the compileClasspath has the OS attribute set on the gradle side.
   And then rework this function to know what is a native file and what is an actual library.
