Run a Jenkins job every one minute using H/1 * * * *
Try * * * * * to run every minute.
Unfortunately H/1 * * * * does not work due to open defect.
Defect: https://issues.jenkins-ci.org/browse/JENKINS-22129
Your intuition is right, H/1 is supposed to behave like "run every minute".
However, there is a well-known bug in Jenkins. See JENKINS-22129.
Currently, H/1 behaves like "run every hour".
