Details

The common project depends on common-api through implementation(commonClasses(project(":common-api"))). However, the vanillaextract tool that commonClasses uses seems to expose specifically the common classes through a capability, <group>:common-api-common in this case; this capability in the dependency is exposed on publish (see the module metadata), resulting in an impossible-to-consume common module that causes a variant incompatibility error when you attempt to depend on it as a runtime dependency, as there is no published variant on the common-api project with that capability.

Thanks for the report! I thought I'd turned off publishing Gradle metadata for the common jar, but clearly not — will do so now.

Oh, what are you depending on the common jar for? I'd expect the the common jar to crash as soon as you try to use anything from it, as all the platform specific hooks are missing.

Not quite sure to be honest; it wasn't actually my project I was debugging when I ran into this 😂. Thanks for getting it fixed.

I was the one that ran into it lol.

I get

so what do I do??

I fixed it by updating to 1.111.0 lol

What are you using the common jar for? External mods should really only be going through the API.
