Problem Description

The code completion feature of the MapStruct Support plugin is not working properly when using the lombok @SuperBuilder (lombok.experimental.SuperBuilder) annotation.

Steps to Reproduce

1. Create a new Java class.
2. Add the lombok @SuperBuilder annotation to the class.
3. Try to use code completion for any field in @Mapper annotation.

Expected Behavior

When using the @SuperBuilder annotation, the code completion feature should suggest the available fields.

Actual Behavior

The code completion feature does not suggest any fields or methods.

Screenshots and Code Snippets

// Class with annotation
@Getter
@Setter
@SuperBuilder
@NoArgsConstructor
public class Builder {
    private Integer bar;
}

// Class without annotation
@Getter
@Setter
public class WithoutBuilder {
    private Integer foo;
    private Builder innerBuilder; // To show that autocompletion works for inner builders
}

// Mapper with broken code completion
@Mapper
public interface BuilderMapper {
    @Mapping(target = "", source = "")
    Builder map(WithoutBuilder builder);
}

Doesn't work for class with @SuperBuilder:

But works for class without @SuperBuilder:

Even works for class with @SuperBuilder which inside a class without @SuperBuilder:

Additional Information

Generated class for @Mapping(target = "bar", source = "foo") to show that it is valid mapper:

@Generated(
    value = "org.mapstruct.ap.MappingProcessor",
    date = "2023-11-13T17:06:33+0700",
    comments = "version: 1.5.5.Final, compiler: javac, environment: Java 17.0.8 (BellSoft)"
)
public class BuilderMapperImpl implements BuilderMapper {

    @Override
    public Builder map(WithoutBuilder builder) {
        if ( builder == null ) {
            return null;
        }

        Builder builder1 = new Builder();

        builder1.setBar( builder.getFoo() );

        return builder1;
    }
}
