I use the maven plug “maven-assembly-plugin” to package the dependencies and
code together into a jar。The pom like that
{code:java}

<version>1.11.1</version>

I also find that the jdbc-connector has no problem， Only kafka-connector get
the exception， And also no problem when use DataStream on kafka-connector。
It seems that the FactoryUtil did not find the KafkaDynamicTableFactory

> 'properties.group.id' = 'testGroup',
> 'format' = 'csv',
> 'scan.startup.mode' = 'earliest-offset'

> {code}
> I get a exception
> {code:java}
> Caused by: org.apache.flink.table.api.ValidationException: Cannot discover a
