How to change the oracle JDBC driver jar file name and version in JRS 9.0.0

During upgrade to JRS 9.0.0, customers encountered below error :

------------------------
     [echo] Validating administrative database connection at jdbc:oracle:thin:@rk624932-ewo44:1521:mdb. Phase: [test]
     [echo]   Specified JDBC driver jar not found on this path: 
     [echo]   C:/js-jrs_9.0.0_bin/jasperreports-server-pro-9.0.0-bin/buildomatic/conf_source/db/oracle/jdbc/ojdbc8-23.2.0.0.jar
------------------------

As per this error, it is looking for "ojdbc8-23.2.0.0.jar" jar file of version 23.2.0.0.

From oracle website using below URL navigate to "23.2.0.0" version and download the jar file for this version and need to rename as "ojdbc8-23.2.0.0.jar". 
https://www.oracle.com/database/technologies/appdev/jdbc-drivers-archive.html

The name of jar file is coming from "db.properties" file located at : ...\jasperreports-server-pro-9.0.0-bin\buildomatic\conf_source\db\oracle\
by default it's configured to the latest ojdbc8 version.
-----------------
# for maven: artifact info so unit tests can get to the correct jdbc driver
maven.jdbc.groupId=com.oracle.database.jdbc
maven.jdbc.artifactId=ojdbc8
maven.jdbc.version=23.2.0.0
-----------------

If you wish to modify it, you can make changes to the properties mentioned above in the "db.properties" file.
