java.lang.NoClassDefFoundError: ch/qos/logback/classic/spi/ThrowableProxy

Hi all.

Probably this is not the correct place to post this message, but I didn't find a satisfactory response in google.

In my app a job is started periodically to update a table in a mongo db. The app runs normally but after some while I receive the following exception:

Exception in thread "quartzScheduler_Worker-4" java.lang.NoClassDefFoundError: ch/qos/logback/classic/spi/ThrowableProxy

The app run as a standalone jar and I am using grails 3.1.11.

Am I doing something wrong?
Thanks.
