请仔细阅读官网文档本地调试相关,不要断章取义,需逐字查看,以及查看相关截图

dinky1.0版本，本地编译成功之后，代码中还是提示缺少FlinkUtil类？ 看一下dinky-flink对应的pom.xml是否缺失依赖包，然后clean后，重新编译

org.apache.flink flink-core ${flink.version}

Caused by: org.apache.flink.table.api.ValidationException: Field names must be unique. Found duplicates: [w1$o0, w0$o0]

编写flinksql作业，提交任务出现以上报错；在一个作业中使用with as语法写多个子查询（t1, t2, t3,t4), 每个子查询中会使用一些开窗函数，测试发现在最后一个子查询中使用开窗函数出现以上报错，实际上无这些字段名，字段别名检查也无重复。这个报错的原因是什么；把最后一个子查询拆分到另一个作业单独处理，任务正常提交。
