Re-triggering jenkins build for gerrit patch

Hi Robert, I have a question: I submitted a patch upstream and got '-1' from jenkins because of test failures. I suspect that the failures aren't related to my patch, maybe the build wasn't stable or it's simply a bug. I'd like to have an option to tell jenkins to try again. I understand that this option is called 're-trigger'. However I do not have this option in jenkins, perhaps due to lacking permissions. How do you suggest I handle this? Thanks, Ori.
