Exception indicates that some other library or framework is using Hymanson 1.x, and requires 1.x jars. You are using Hymanson 2.x, classes of which live in com.fasterxml.Hymansonpackage; but as per exception, ones in org.codehaus.Hymansonare needed.
异常表示某些其他库或框架正在使用 Hymanson 1.x，并且需要 1.x jar。您正在使用 Hymanson 2.x，其中的类存在于com.fasterxml.Hymanson包中；但作为例外，org.codehaus.Hymanson需要in 。

Even if you set up build path, you have to add classpath during runtime. Check up deployment assembly in eclipse
即使您设置了构建路径，您也必须在运行时添加类路径。在 Eclipse 中检查部署程序集
