我在我的项目中使用Lombok库,我无法使用@Builder外部包中注释的类.

有没有办法让建筑师公开？

错误是:

以下是我的组件的代码形式:

import {Component, OnInit, Output, Input, EventEmitter} from "@angular/core";
import {FormControl, Validators, FormGroup} from "@angular/forms";
import {ReferentialService} from "../shared/referential.service";

@Component({
  selector: 'app-form',
