I have a freestyle Jenkins job that contains a Maven Repository Artifact build parameter. I try running the jenkins cli command like this (not exact command, but very similar):
jenkins -jar jenkins-cli.jar -s https://jenkins.excellus.com -i jenkinskey.txt build TestJobName -p "com.excellus.testartifact=2.0.0"

Intention is to run the build with the artifact version being 2.0.0. What I get, instead, after typing in the passphrase for the SSH key is this:

Comment on the source file seems to indicate that the VersionParameterDefinition isn't supposed to be set that way – but I don't know how we can get the CLI to call a different method.
