Question

我正在测试helloworld石英工作。我复制了一个现有的工作并将其粘贴在grails-app / jobs文件夹中。我把它命名为TestJob.groovy。我只是用println消息每分钟开始它。我在cron表达式中犯了一个错误。我删除了这个作业并重新启动了应用程序，我收到以下错误消息。奇怪的是看起来文件仍然存在，因为错误提到错误是在文件TestJob.groovy但我已经删除了这个文件。我尝试清理项目并重建它，我仍然得到错误。感谢您解决此错误并正常重新启动应用程序的任何帮助。谢谢！

Answer 1

做一个grails clean并清除.slcache做了。也许缓存是罪魁祸首。

石英作业即使在删除后仍然存在？
