Unable to launch liquibase using command line

When I run the following command from the prompt I get the error below for version 3.6.1 and 3.6.0. whereas when I run the same command for 3.5.3 , it gives the response that command not passed.

However when I run the liquibase shell script it works fine. I even tried adding the jars to the classpath it still gives the same error. Below are the errors and the steps that I had followed.

Any advice ?
