Connecting to AWS Aurora postgres fails

Trying to navigate connecting to an instance from a jump box. psql works fine.

Unexpected error running Liquibase: liquibase.exception.DatabaseException: liquibase.exception.DatabaseException: Connection could not be created to
jdbc:postgresql:aurora//instance-name-here

liquibase.properties file:
url=jdbc:postgresql:aurora//instance-name-here
driver=org.postgresql.Driver
classpath: postgresql-42.2.8.jar
username:secretUser
password:abcdeghijklmnopassword
changeLogFile: dbchangelog.postgresql.sql

I’ll answer my own question. Get rid of the Driver= and don’t use it.
