Running Liquibase Commands using PowerShell

I have been using Liquibase for several years to deploy changes to our DB2 databases. Currently, I have been trying to create a powershell script to execute Liquibase but I seem to be having problems when it comes to trying to pass the parameters. Although I feel like I might be able to overcome the problem over time, I am a bit short on that very thing. Has anyone had any success executing Liquibase commands from Powershell that might be able to provide some examples?

Any help would be appreciated.
