This may be intentional, but it's making it difficult to spot when builds failed.

Yes, that’s intentional. Jenkins is just a constant stream of security issues, outdated and unmaintained plugins. It’s not manageable to keep it open to the public Internet.

I hope to replace this whole ducttape and glue with debusine later this year, but it’s still to early in development.
