Bitbucket Restore Client Exception :: java.sql.DriverManager.getConnection(Uknown Source)

[Mika Nuotio]

I am attempting to restore Bitbucket using the bitbucket-resttore-client.jar application:

https://confluence.atlassian.com/bitbucketserver/using-the-bitbucket-server-backup-client-776640064.html

The application runs and successfully unpacks the data to the %BITBUCKET_HOME% directory defined in the backup-config.propertis file:

bitbucket.home=C:\\Atlassian\\Restore\\Bitbucket\\bitbucket-backup-client-3.6.0\\BITBUCKET_HOME

Then the application exits:

c:\Atlassian\Restore\Bitbucket\bitbucket-backup-client-3.6.0>java -jar bitbucket-restore-client.jar ..\bitbucket-20191030-131759-251.tar

java.lang.reflect.UndeclaredThrowableException: null

at java.sql.DriverManager.getConnection(Unknown Source)
... 18 more frames available in the log file

The following JDBC parameter values in backup-config.properties were used:

jdbc.driver=org.postgresql.Driver

jdbc.url=jdbc:postgresql://bitbucketserver:5432/bitbucketdb

Jira and Confluence are running on the same server 'bitbucketserver' and are using the same PostgreSQL database, so I am confident that the issue is not related to our PostgreSQL instance.

I suspect that there might be an issue with jdbc.driver...

Any help would be appreciated.
