Updating plugins in jenkins via nexus?

Question

linux

In general, the situation is such that it is necessary to update plugins on jenkins via nexus.
I found this article to generate update-center.json https://stackoverflow.com/questions/20128118/how-t
... : But the project does not build and collapses at the -h step, writes "-h" is not a valid option
What am I doing wrong?
Or is there another way to update?
