@Transient field breaks application context

[kirill-kravchenko]

Hi!
I'm using infobip-spring-data-jdbc-querydsl-boot-starter 6.2.1 version with querydsl 5.0.0
And when I use @Transient like in the following block:

@Table("entity")
@Data
@Builder
@RequiredArgsConstructor
public class Entity {

    @Id
    private final Long id;

    @Transient
    private final boolean isNew;
}

I get exception:

Failed to load ApplicationContext
java.lang.IllegalStateException: Failed to load ApplicationContext
...

Looks like #18 problem.

Hello,
if I remember correctly, a constructor without @Transient field is required and it should be marked with @PersistenceConstructor.
For details check out related test classes.
