Hi Matt,

Ever find a solution? I ran into the same thing trying to add this plugin to my jenkins on a docker image.
When i look if there's a signing issue with this file, it looks unsigned, just like the other hpi files i add:

jarsigner -verify -verbose -certs ssh-slaves.hpi
jar is unsigned. (signatures missing or not parsable)

Tried it outside of docker > same result

Regards,
David
