Quartz job exists even after deleting it? - grails

Question

I was testing a helloworld quartz job. I copied an existing job and pasted it in grails-app/jobs folder. I named it TestJob.groovy. I simply made it to fire every minute with a println message. I had made a mistake in the cron expression. I deleted this job and restarted the app and i get the following error message. The strange thing is looks like the file still exists since the error mentions the error was in the file TestJob.groovy but i had already removed this file. I tried cleaning the project and rebuilding it and i still get the error. I appreciate any help in resolving this error and restarting back the app normally. Thanks!

Answer 1

doing a grails clean and clearing .slcache did it. Maybe the cache is the culprit.
