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 with mongodbreader/pom and MongoDBReader.java at line 200, then inspect how the plugin JAR is packaged and loaded by DataX. Reproduce the reported run and verify that the packaged reader can load the required class without the reported NoClassDefFoundError.
