Could not find or load main class liquibase.integration.commandline.LiquibaseCommandLine

We are upgrading from 3.5.5 to 4.9.1 . Changed the Java command as mentioned here

But getting the below error while executing.
Error: Could not find or load main class liquibase.integration.commandline.LiquibaseCommandLine
Caused by: java.lang.ClassNotFoundException: liquibase.integration.commandline.LiquibaseCommandLine

Any ideas on this?
