Subject [GitHub] flink issue #2548: [FLINK-4677] fail if user jar contains no executions
Date Wed, 28 Sep 2016 16:07:36 GMT
Github user mxm commented on the issue:

    That's a good point @greghogan. We don't have a standard way to print a usage message.
A disadvantage of the approach in this PR is that we will display an error message which might
actually mask any usage information printed. An alternative approach would be to simply exit
(perhaps with a small hint). That might actually be nicer.

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
with INFRA.
