Quartz scheduler cron expression not working - quartz-scheduler

Question

I am wondering why this Quartz cron expression isn't working:
<trigger>
<cron>
<name>jobtriggername</name>
<group>groupname</group>
<job-name>jobname</job-name>
<job-group>jobgroup</job-group>
<misfire-instruction>MISFIRE_INSTRUCTION_DO_NOTHING</misfire-instruction>
<cron-expression>0 0/30 0-6,12,19-23 * * ?</cron-expression>
</cron>
</trigger>
When I start the application server the following exception is thrown:
ERROR [org.quartz.plugins.xml.XMLSchedulingDataProcessorPlugin] (MSC service thread 1-8 ) [] Error scheduling jobs: Encountered 2 validation exceptions.: org.quartz.xml.Vali

I don't think this is some esoteric cron expression?

Answer 1

Please go through some examples here.
0 0/30 0-6,12,19-23 * * ?
Here 0-6,12,19-23 section seems to be the problem. Try replacing it with
0,1,2,3,4,5,6,12,19,20,21,22,23
Even though some other vendors support complex cron expressions like 0 0/5 14,18,3-39,52 ? JAN,MAR,SEP MON-FRI 2002-2010, I think Quartz does not. If this not works, please give your cron requirement.
