以源码运行nacos2.0.3报错

以源码运行nacos2.0.3报错

加入nacos模块的源码运行时，报错：
No enum constant com.fasterxml.jackson.annotation.JsonTypeInfo.Id.DEDUCTION；
nacos版本2.0.3；解决方案直接看最后。

经过查找发现是版本问题：
原本用的版本：

这里的版本是根据官网推荐用的，首先nacos选用的2.0.3版本，所以spring-cloud-alibaba就是2.2.7版本的。
再根据cloud-alibaba选择对应的版本：

但是这个版本运行报错；所以换成如下版本：

再次运行：
