Issue on creating and using a custom connector in Ververica

[Natu Lauchande]

Good day Flink community,

Apache Flink/Ververica Community Edition - Question

I am trying to add a custom connector to Ververica community edition and keeps giving me the following error: "The jar contains multiple connector. Please choose one.", it doesn't allow me to choose more jars. I am testing with the following repo generated custom connectors: https://github.com/deadwind4/slink/tree/master/connector-es6

My specific question is there anything specific missing from this repos that we should add to signal ververica about a custom record

I am constantly receiving the following message attached ("The jar contains multiple connectors, please select one.") and i can't select any option. 

Thanks,

Natu

Hi Natu,

the message is of course a bit unfortunate and misleading, but the issue here isn't that multiple connectors are found, but that none are found. The repository you linked to implements a connector using the old connector stack, but Ververica Platform only supports the new stack, see [1].

From a quick look it also seems to be missing the entry in META-INF/services which would be required for the factory discovery to work.

In my personal GitHub profile I have an example[2] for a connector using the new stack which also works in Ververica Platform (it's not for Elasticsearch, though).
