[1.16.5] Can't find the fabric/forge resource in the resource manager on compile only mode

[SAGESSE-CN]

Issue 1

can't launch the fabric (client and server) project, it will throw duplicate fabric loader classes. logs

I force dependencies to the same version to solve this problem, but I hope it should be fixed.

configurations.configureEach {
    it.resolutionStrategy {
        it.force "net.fabricmc:fabric-loader:0.18.1"
    }
}

Issue 2

can't find the fabric/forge resource in the resource manager on compile only mode.

i add a test into MixinTitleScreen to reproduce issue. logs

and the problem also exists on the server side.

ResourceManager resourceManager = Minecraft.getInstance().getResourceManager();
resourceManager.getResource(new ResourceLocation("examplemod:common/a.json")); // should work in the :fabric:runClient and the :forge:runClient 
resourceManager.getResource(new ResourceLocation("examplemod:fabric/b.json")); // should work in the :fabric:runClient
resourceManager.getResource(new ResourceLocation("examplemod:forge/c.json")); // should work in the :forge:runClient 

Project

The test project from architectury templates.

The first issue isn't anything we can fix. It happens because older versions of Fabric Loom will be remapped and newer versions won't, so the newer version won't override the older version properly. Forcing the dependency, or excluding the old version of Fabric Loader from whatever pulls it in, is the best solution.

Are you referring to Arch Plugin's compile-only mode? If so, you also need to create loom.mods entries for the common project's resources. See the guide for details.

I make sure that the configure is correct.

it work normally in 1.18.2+, you can see that in the git action

maybe bacause the loader not support multi root path?
