Jakarta EE 10. Javax instead Jakarta

[Gio-Ayiman]

I would like to know if any of you had a bug when generating mappers. Rather than importing jakarta.persistence.context it imports javax.persistence

@Gio-Ayiman can you please be a bit more precise? What did you try? MapStruct does support Jakarta EE 10.

If you use the jsr330 / cdi component model then MapStruct is going to use javax if those javax classes are on the classpath. Otherwise it is going to use jakarta.

If you have both javax and jakarta on the classpath then you should use jakarta / jakarta-cdi as component models.

I noticed that mapstruct seems to use the javax.annotation.Generated import regardless of component model used. I now have this in my compiler-plugin:

<plugin>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>${maven-compiler-plugin.version}</version>
      <configuration>
        <release>${jdk.version}</release>
        <annotationProcessorPaths>
          <path>
            <groupId>org.mapstruct</groupId>
            <artifactId>mapstruct-processor</artifactId>
            <version>${mapstruct.version}</version>
          </path>
        </annotationProcessorPaths>
        <showWarnings>true</showWarnings>
        <compilerArgs>
          <arg>
            -Amapstruct.suppressGeneratorTimestamp=true
          </arg>
          <arg>
            -Amapstruct.suppressGeneratorVersionInfoComment=true
          </arg>
          <arg>
            -Amapstruct.verbose=true
          </arg>
          <arg>
            -Amapstruct.defaultComponentModel=jakarta
          </arg>
        </compilerArgs>
      </configuration>
    </plugin>

And it only changes the inject import to jakarta:

    import jakarta.inject.Named;
    import jakarta.inject.Singleton;
    import javax.annotation.processing.Generated;
    
    @Generated(
        value = "org.mapstruct.ap.MappingProcessor"
    )
    @Singleton
    @Named
    public class TimeSlotMapperImpl implements TimeSlotMapper {

Is there something I am missing here? I have the jakarta.annotations on my classpath btw and using java21 (which has the javax.annotation on the classpath in its core).

@billerby javax.annotation.Generated is a Java 8 JDK (https://docs.oracle.com/javase/8/docs/api/javax/annotation/Generated.html) annotation, and javax.annotation.processing.Generated is available from Java 9 (https://docs.oracle.com/javase/9/docs/api/javax/annotation/processing/Generated.html). They are both meant for the same thing and MapStruct is using one or the other depending on the source level of the project. When using Java 9+ then javax.annotation.processing.Generated will be used.

This has nothing to do with the component model
