Getting MySqlConnection error

[prayag1m95]

When I try running the cdc-parent code in eclipse it gives me following error -

ERROR embedded.EmbeddedEngine: Unable to initialize and start connector's task class 'io.debezium.connector.mysql.MySqlConnectorTask' with config:

Caused by: com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure

Also, google_application_credentials gives me null output.

how did you solve this? I'm having the same error

I believe there are missing parts of the stack trace here, under Caused by: com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure.

It would probably reveal the root cause of the connection (which is usually related to networking / firewall).
