我最近通过在我的 pom.xml 中添加以下行来添加本文所述的字节码增强功能：

<plugin>
  <groupId>org.hibernate.orm.tooling</groupId>
  <artifactId>hibernate-enhance-maven-plugin</artifactId>
  <version>5.3.10.Final</version>
  <executions>
    <execution>
      <configuration>
        <enableDirtyTracking>true</enableDirtyTracking>
      </configuration>
      <goals>
        <goal>enhance</goal>
      </goals>
    </execution>
  </executions>
</plugin>

当我尝试运行时mvn clean install，出现以下错误：

[ERROR] Failed to execute goal org.hibernate.orm.tooling:hibernate-enhance-maven-plugin:5.3.10.Final:enhance (default) on project backend: Unable to enhance class: ExtrasBookingRequestDTO$ExtrasBookingRequestDTOBuilder.class: Failed to enhance class ExtrasBookingRequestDTO$ExtrasBookingRequestDTOBuilder: Unexpected type reference on method: 19 -> [Help 1]

从异常中我猜它与 Lombok 生成的 Builder 有关。IllegalStateException: Unexpected type reference on method: 19不幸的是，我在互联网上找不到任何有关的信息。这是 maven 失败的类：

import lombok.*;

import javax.validation.Valid;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;
import java.util.Objects;
import java.util.Set;
import java.util.UUID;

@Builder
@AllArgsConstructor
@NoArgsConstructor
@Getter
@Setter
public class ExtrasBookingRequestDTO {

    @NotNull
    private Set<@Valid BookingExtraDTO> extras;

    @Size(max = 1000)
    private String notice;

    @NotNull
    private UUID temporaryBookingId;

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        ExtrasBookingRequestDTO that = (ExtrasBookingRequestDTO) o;
        return Objects.equals(extras, that.extras) &&
            Objects.equals(notice, that.notice) &&
            Objects.equals(temporaryBookingId, that.temporaryBookingId);
    }

    @Override
    public int hashCode() {
        return Objects.hash(extras, notice, temporaryBookingId);
    }
}
