自定义mongodbreader，打包上传mongodbreader-0.0.1-SNAPSHOT.jar后，运行报错，在mongodbreader的pom文件中添加fastjson2依赖后再次打包上传仍然报错

Start at MongoDBReader.java:200 and inspect the mongodbreader pom and the produced mongodbreader-0.0.1-SNAPSHOT.jar. Check how the runtime plugin classpath handles the fastjson2 dependency, then reproduce the reader startup failure. Done means the packaged reader starts without the com/alibaba/fastjson2/JSON ClassNotFoundException.
