Validate a cron expression in JIRA 8.X

[Normann P_ Nielsen _Netic_]

as direct access to Quartz is removed, see https://developer.atlassian.com/server/jira/platform/jira-7-0-general-changes/#quartz-scheduler-removed

Im using the "atlassian-scheduler API provides a CronExpressionValidator"

But I cant get it to work:

import com.atlassian.scheduler.cron

CronExpressionValidator validator = new CronExpressionValidator()

return validator.isValid("* * * * *")

Result:

unable to resolve class com.atlassian.scheduler.cron @ line 4, column 1. import com.atlassian.scheduler.cron ^ Script126.groovy: 6: unable to resolve class CronExpressionValidator @ line 6, column 25. CronExpressionValidator validator = new CronExpressionValidator() 

Another try:

import com.atlassian.scheduler.cron.CronExpressionValidator;

CronExpressionValidator validator = new CronExpressionValidator()

return validator.isValid("* * * * *")

Result

You cannot create an instance from the abstract interface 'com.atlassian.scheduler.cron.CronExpressionValidator

I can see that CronExpressionValidator is only interface. You need to use its implementation and the only I can see is com.atlassian.scheduler.caesium.cron.CaesiumCronExpressionValidator. So try to use:

import com.atlassian.scheduler.cron.CronExpressionValidator;
import com.atlassian.scheduler.caesium.cron.CaesiumCronExpressionValidator;

CronExpressionValidator validator = new CaesiumCronExpressionValidator()

return validator.isValid("* * * * *")

 I'm not sure as I do not know your project configuration but you might need to add dependency to atlassian-scheduler-caesium if you're working with maven project.

Awesome, thanks - works in the Scriptrunner Console
