Using Jenkins 1.642.4, I installed an older version of my plugin from a hpi file using the Jenkins CLI and did a safe restart. When I try to install a newer version of the same plugin using the Jenkins CLI, http://localhost:8080/pluginManager/installed still shows the older version is installed even after a safe restart.

Manually uploading the files to the server works fine, I can upgrade/downgrade and install any specific version without trouble. There is only an issue when I use the Jenkins CLI

When installing a plugin manually, it creates a

{plugin-name}.bak

file but when I use the CLI it creates a

{plugin-name}-{version}.bak

I assume this might be the cause of the issue
