I finally resolved my issue and it has nothing to do with Maven or liquibase.
I upgraded my postgresql driver version and it's fixed. After examining the slightly older version in my local repo, it turns out that although unzip tolerates the archive, jar does not. A nicer error message would have been good, but I am not sure that that is really a Maven issue. It likely has to do with the particular JVM and class loader that I am using (in my case that the Apple Java implementation). Thanks to everyone who made suggestions.
