Class <org.gradle.api.publish.internal.metadata.ModuleMetadataSpec$Variant> is not annotated (directly or via its package) with @org.gradle.api.NonNullApi in (ModuleMetadataSpec.java:0)

- `name`: The name of the variant. A string. The name must be unique across all variants of the component.
- `attributes`: optional. When missing the variant is assumed to have no attributes.
- `available-at`: optional. Information about where the metadata and files of this variant are available.

        The only attribute distinguishing these variants is 'org.gradle.native.architecture'. Add this attribute to the consumer's configuration to resolve the ambiguity:
          - Value: 'x86-64' selects variant: 'natives-windows-runtime'
