How to skip @Transient fields in querydsl generation?

I have an @Entity class that I use querydsl code generation on.

Problem: my entity has a parent entity which contains some @Transient fields. And those are not skipped during generation.

package com.domain.myentity

@Entity
public class MyEntity extends AuditingEntity {

}


package com.auditing

@MappedSuperclass
public class AuditingEntity {
    @Transient
    private transient Object obj;
}

package-info.java: 

@QueryEntities(value = MyEntity.class)
package com.domain.myentity

import com.querydsl.core.annotations.QueryEntities;
import com.domain.myentity.MyEntity;

Question: how can I tell querydsl to ignore any @Transient fields automatically? Currently the root cause is probably that the AuditingEntity is in a different folder than the domain entity, and therefore not listed in the package-info.java of querydsl. But how could I solve it without having to move the auditing entity?

If you want to prevent QueryDsl from mapping a field or method you should use the @QueryType - annotation with PropertyType.NONE.

The value PropertyType.NONE can be used to skip a property in the query type generation. This case is different from @Transient or @QueryTransient annotated properties, where properties are not persisted. PropertyType.NONE just omits the property from the Querydsl query type.

@Entity
public class MyEntity {


    @QueryType(PropertyType.NONE)
    public String stringNotInQuerydsl;

}

See the official documentation here

Could you try transient declaration as transient String obj; instead of 

@Transient
private Object obj;
