Is there a import cycle in your project?
occur "unknown pattern" when having a import cycle like:

 import cycle not allowed
 package .../cmd/task
    imports .../sku/intern/impl
    imports .../sku
    imports .../sku/task
    imports .../sku

wire works fine when I fix the import cycle

[jayzhuang]

panic(wire.Build(domain_service.ProvidePRDomainService(), wire.Struct(new(ProcurementRequestServiceImpl),"*")))
should be
panic(wire.Build(domain_service.ProvidePRDomainService, wire.Struct(new(ProcurementRequestServiceImpl),"*")))

Note domain_service.ProvidePRDomainService should not be invoked, wire.Build expects a provider, not the thing returned by the provider :)

@LFernandoC can you confirm if this fixes things for you?
