Java Lombok 报错(IllegalAccessError: class lombok.javac.apt.LombokProcessor)解决方法

使用Lombok的@Data类：

import lombok.Data;
@Data
public class Ingredient {
    private final String id;
    private final String name;
    private final Type type;
    public enum Type {
        WRAP, PROTEIN, VEGGIES, CHEESE, SAUCE
    }
}

解决方法：

指定使用Lombok依赖的版本，

<dependency>
  <groupId>org.projectlombok</groupId>
  <artifactId>lombok</artifactId>
  <version>1.18.20</version>
</dependency>

或者

<plugin>

    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.1</version>
    <configuration>
