I have a scenario where in a job group has three jobs A B and C. Job A runs and generates file or files that become dependency for either job B or Job C or both jobs. Or job A may run but not generate file at all. Now for job B and C those jobs need to run only if the file dependency generated by the job A is met.If Job A does not generate file then these job should just complete normally as there is another job groups that is dependent upon this job group. How can I set this job group to complete normally if the files don't get generated at all?
