当Intellij IDEA升级到2020.3版本时，如果你的项目恰恰使用了Lombok，那么恭喜你，十有八九会中招，在编译的时候产生如下错误：
java: You aren't using a compiler supported by lombok, so lombok will not work and has been disabled.
Your processor is: org.jetbrains.jps.javac.$Proxy18
Lombok supports: sun/apple javac 1.6, ECJ
但是Maven却可以正常构建。
根据IntelliJ的说法这是因为Lombok导致的，而且拒绝在IDEA侧解决，需要等Lombok升级，具体撕逼内容如下：

虽然我对于他们这种神仙打架的行为很好奇，也乐意观看，但是我还得搬砖啊。上面的链接中也给出了解决方案，就是在编译的命令行参数中加入-Djps.track.ap.dependencies=false，具体位置如下：
再次编译，顺利通过。
追加：
项目中如果有在使用MapStruct，那么在升级到IntelliJ IDEA 2020.3 EAP时， 也会产生如下错误：

解决方法同上，就是加入编译参数-Djps.track.ap.dependencies=false。
