== Introduction
The Quartz Plugin allows your Grails application to schedule jobs to be executed using a specified interval or cron expression. The underlying system uses the https://www.quartz-scheduler.org/[Quartz Enterprise Job Scheduler] configured via Spring, but is made simpler by the coding-by-convention paradigm.
Since version `1.0-RC3`, this plugin requires Quartz version `2.1.x` or higher and no longer supports Quartz version `1.8.x`.
