There are some proto files which are still under the 'google' directory and

option csharp_namespace = "Google.Protobuf.WellKnownTypes";
option go_package = "github.com/golang/protobuf/ptypes/any";
option java_package = "com.google.protobuf"; // <======== here
option java_outer_classname = "AnyProto";
option java_multiple_files = true;
option objc_class_prefix = "GPB";
