Force push to Gerrit even with no new changes

Question

I want to push a patchset to Gerrit which has already been pushed. Originally when the patches were sent up, the build system did not trigger. I need to trigger it again by resubmitting all patches.

Gerrit rejects this with

 ! [remote rejected] HEAD -> refs/for/branch (no new changes)

I know there are no new changes but I want to push anyway. How can I do this?

--force flag has no effect.

Answer 1

Execute "commit --amend, change the commit message and push again.
