IDEA升级到2020.3后，使用lombok会报以下错误：

java: You aren't using a compiler supported by lombok, so lombok will not work and has been disabled.
  Your processor is: com.sun.proxy.$Proxy24
  Lombok supports: sun/apple javac 1.6, ECJ

这个问题需要将lombok升级到1.18.16版本：

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.16</version>
</dependency>

解决！
