Refire quartz.net trigger after 15 minutes if job fails with exception

Question

I have searched for an answer on how to retrigger a job after a ceratin amount of time, if the job throws an exception. I cannot see any simple way of doing this.

if I set my trigger up like this:

JobDetail job = new JobDetail("Download catalog", null, typeof(MyJob));
job .Durable = true;
Trigger trigger= TriggerUtils.MakeDailyTrigger(12, 0);
trigger.StartTimeUtc = DateTime.UtcNow;
trigger.Name = "trigger name";
scheduler.ScheduleJob(job , trigger);

And MyJob look like this:

public class MyJob : IJob
{
    public void Execute(JobExecutionContext context)
    {
        var service = new service();


        try
        {
            service.Download();
        }
        catch (Exception)
        {
            throw;
        }

    }
}

how do I make the trigger to refire/retrigger after there is gone 15 minutes if the service.Download() call throws some sort of Exception?

Actually, its not necessary to create a new JobDetail like described by LeftyX. You can just schedule a new trigger that is connected to the JobDetail from the current context.

public void Execute(JobExecutionContext context) {
    try {
        // code
    } catch (Exception ex) {
        SimpleTriggerImpl retryTrigger = new SimpleTriggerImpl(Guid.NewGuid().ToString());      
        retryTrigger.Description = "RetryTrigger";
        retryTrigger.RepeatCount = 0;
        retryTrigger.JobKey = context.JobDetail.Key;   // connect trigger with current job      
        retryTrigger.StartTimeUtc = DateBuilder.NextGivenSecondDate(DateTime.Now, 30);  // Execute after 30 seconds from now
        context.Scheduler.ScheduleJob(retryTrigger);   // schedule the trigger

        JobExecutionException jex = new JobExecutionException(ex, false);
        throw jex;
    }
}

This is less error prone than creating a new JobDetail. Hope that helps.
