And when the day comes that "AI ML ... can help SO website", it won't be users helping users, so we won't worry about people deciphering pictures of text. In the meantime, you can help your fellow helpers today; Why not upload images of code/errors when asking a question?.

Answer 1

Try * * * * * to run every minute.

Unfortunately H/1 * * * * does not work due to open defect.

The idea is to use H (so that Jenkins can to balance) if there are hundreds of jobs who have the same build period. */1 * * * * will do the same. – Central

The question is more towards using H instead of * i.e. why H/1 * * * * is picking/scheduling the job for 1 hour difference (instead of 1 minute difference) while H/2 * * * * schedules the job for 2 minutes (as expected). – Central

I see what you are trying to do. There seems to be an open defect - issues.jenkins-ci.org/browse/JENKINS-22129 – Sense

would this work? H(0-59)/1 * * * * – Malaya

Answer 2

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".
