Cannot add Copy Artefacts build step

Jenkins setup: Jenkins 2.541.3 + Copy Artifact Plugin Version 795.ve8e151429b_27

Hi, we want to add a Copy Artifact build step to a pipeline but when we click:

Configure > Add build step > Copy artefacts from another project

Nothing happens. Can you suggest what may be wrong please?

You’re not talking about pipeline but a freestyle project.
Hard to tell what could be wrong. Check in the browser console for any errors.
Is this the only step that is not working or is it general problem that no steps can be added at all?

Hi Markus, thanks for your reply. Apologises for saying it was a pipeline, it is indeed a freestyle job.

The system log shows nothing for that action. Other build steps work, it is only the Copy Artifact build step that can’t be added.

The browser console shows:

/scripts/utilities.js net::ERR_ABORTED 404 (Not Found)

Our controller has:

/var/cache/jenkins/war/scripts/utilities.js

In case it is relevant, the controller is behind nginx reverse proxy.
