MapStruct implementations not being generated when using `mvn package`-CodePudding

I have annotated my classes with @Mapper. When I examine the target folder, the mapper implementations are not there. The weird part is, when I compile using IntelliJ's build functionality, the classes are generated and I can see them under the target folder. But when I compile using mvn clean package or just mvn package the classes are not generated. What can cause this?

CodePudding user response：

Only thing I can think of, that slipped my mind the first time I used mapstruct is the classes need to be interfaces, this is a sample class I have that uses mapstruct:

import org.mapstruct.Mapper;
import org.mapstruct.factory.*;

@Mapper
public interface BeaconMapper {

    public BeaconMapper INSTANCE = Mappers.getMapper( BeaconMapper.class ); 

    public BeaconDTO BeaconToBeaconDTO( Beacon beacon );
    public Beacon BeaconDTOToBeacon( BeaconDTO beaconDTO );
}

I reviewed your pom.xml and I don't see anything wrong with it, so I don't think that is the issue, good luck!

CodePudding user response：

I solved the issue thanks to a user over at GitHub - issue link. The problem was with the 1. prefix in the source and target tags. So I removed it:

            <source>17</source> <!-- depending on your project -->
            <target>17</target> <!-- depending on your project -->
            <release>17</release>
