Issue with sql task accessing MySql

The MySql server I'm accessing upgraded to version 8.0.17:

 mysql> select version();+-----------+| version() |+-----------+| 8.0.17    |+-----------+1 row in set (0.00 sec)


So, accordingly, I downloaded the proper driver and linked to it in my task:
        <sql driver="com.mysql.jdbc.Driver"          url="jdbc:mysql://myServerName.myDomain:3306/myDB"          userid="myUser" password="myPassword">          <classpath>            <pathelement path="c:/apache-ant-1.7.0/lib/mysql-connector-java-8.0.17.jar"/>          </classpath>          CALL sp_setBuildStatus('${pk_build}','${full.buildnumber}-${build-time}','${result}');        </sql>
Seems I did the right thing, but still getting the error when I attempt to call this Stored Procedure:

$ ant -f test.xmlBuildfile: test.xml
main:
BUILD FAILEDc:\BuildDeployScripts\test.xml:22: com.mysql.jdbc.exceptions.MySQLNonTransientConnectionException: Client does not support authentication protocol requested by server; consider upgrading MySQL client
Total time: 1 second

Anyone have any idea what I'm running into here?
Thanks,Eric
