Getting error

 Unexpected error running Liquibase: java.lang.RuntimeException: Cannot find database driver: lib/liquibase-redshift-1.0-SNAPSHOT.jar

I tried multiple options under https://github.com/liquibase/liquibase-redshift/releases but did not work . All of them give the same error. 

Is there something obvious I am missing?
