When I have option " Allow missing report" false and no report is found, the job is set to result FAILURE. Also the rest of the reports are skipped.

Also, I think the convention of post-build actions is to make the job UNSTABLE when it fails unless it's a misconfiguration. I guess you could argue that this can indeed be a misconfiguration.
