问题1：flink 1.14 包 org.apache.flink.shaded.guava 版本冲突

根据网友建议，重新引入flink-shaded-guava，重新制定冲突依赖
| <dependency> <groupId>org.apache.flink</groupId> <artifactId>flink-shaded-guava</artifactId> <version>18.0-13.0</version> </dependency> |
继续报异常

最后解决方式：
一开始flink使用的是1.14.2，flink-connector-jdbc版本也是1.14.2；这两个依赖中使用的flink-shaded-guava版本不一致。flink使用的是guava30，connect使用的是guava18。我这边将flink版本降成1.13.6，然后问题就解决了文章来源：https://www.toymoban.com/news/detail-568415.html
备注：目前flink14和flink15没有怎么解决这个问题，带后续解决后，再升级flink集群文章来源地址https://www.toymoban.com/news/detail-568415.html
