erroneous element com.google.type.Date

[zapphyre]

Hi,
probably I have misconfigured something but cannot figure out what for getting this:
No implementation was created for QcMapper due to having a problem in the erroneous element com.google.type.Date. Hint: this often means that some other annotation processor was supposed to process the erroneous element. You can also enable MapStruct verbose mode by setting -Amapstruct.verbose=true as a compilation argument.

I don't know where is the com.google.type.Date type comming from, in proto file definitions I'm using only Timestamp

this is my maven-compiler-plugin config:

example of a mapper that outputs that error:

@Mapper(
        nullValuePropertyMappingStrategy = NullValuePropertyMappingStrategy.IGNORE,
        collectionMappingStrategy = CollectionMappingStrategy.ADDER_PREFERRED,
        uses = {BaseDataMapper.class, ProtobufStandardMappings.class}
)
public interface QcMapper {
	QcSampleInformationRequestDto map(QcSampleInformationRequest request);

	QcSampleInformationRequest map(QcSampleInformationRequestDto requestDto);

	QcSampleInformationResponseDto map(QcSampleInformationResponse response);

	QcSampleInformationResponse map(QcSampleInformationResponseDto responseDto);
}

I have tried to re-shuffle order of path in annotation processing config, but with no luck.
what can be wrong here?

thank you!

I just stumbled upon this same issue. Mapstruct is complaining about com.google.type.Data not being present. This type comes from com.google.api.grpc:proto-google-common-protos, which entur's libraries are including as compileOnly but they seem to be required by the annotation processor if you use it in your project.
Include the mentioned library: com.google.api.grpc:proto-google-common-protos in your project and the error should be gone.
