quartz running only in even minutes

Question

I am using quartz scheduler. While I am creating trigger for my job I am setting start time to it by using trigger.setStartTime() . Now my problem is in first fire time it runs to nearest even time. Let explain the above case with an example. My Trigger start time is: Thu Feb 14 13:53:00 IST 2013 . Recurrance cron expression is for every two minutes. So,the first fire time is Thu Feb 14 13:55:00 IST 2013 . But it is fired at Thu Feb 14 13:54:00 IST 2013 . From there it runs at every two minutes, ie 13:56:00,13:58:00 etc.. But I want to fire the job for every two minutes from start time of the trigger. Please help me to achieve that one.

Thanks in advance.

Answer 1

Which version of Quartz are you using and how are you building your triggers? If you're using version 2.0 or better, you should probably be using the DSL-like TriggerBuilder and SimpleTrigger/SimpleSchedule to build your triggers quickly and less error prone.

Your trigger would end up lokking something like this:

trigger = newTrigger()
    .withIdentity("my-trigger", "my-group")
    .withSchedule(simpleSchedule()
        .withIntervalInMinutes(2)
        .repeatForever())
    .build();
