Cron Expressions

TeamCity allows you to flexibly schedule regular operations using the cron format. Currently, cron-like expressions are supported for schedule triggers.

TeamCity uses Quartz for working with cron expressions. See the examples below or consider using the CronMaker utility to generate expressions based on the Quartz cron format.

Cron format in TeamCity

Cron expressions comprise six fields and one optional field separated with a white space. The fields are respectively described as follows:

Kotlin DSL

Using Kotlin DSL to configure a schedule trigger with the 0 0 0/2 ? * 2-6 * cron expression:

object Build : BuildType({ triggers { schedule { schedulingPolicy = cron { seconds = "0" minutes = "0" hours = "0/2" dayOfMonth = "?" month = "*" dayOfWeek = "2-6" year = "*" } triggerBuild = always() } } })
