Trigger hourly build from scripted Jenkinsfile

Question

Is there a way to trigger a Jenkins job to run every hour using the Jenkinsfile scripted pipeline syntax?

I have seen examples using the declarative syntax

Answer 1

The correct version is in a Jenkinsfile "Declarative Pipeline":

pipeline {
    agent any
    triggers {
        cron('H */4 * * 1-5')
    }
...
}

Answer 2

You could use this snippet for Scripted pipeline syntax:

properties(
    [
        ...  , // other properties that you have
        pipelineTriggers([cron('0 * * * *')]),
    ]
)

Reference for properties is here. You can search for "pipelineTriggers" string and find out that triggers for build can be for example artifactory or something else from this list (extracted 2019-03-23 from linked doc page):
