Apparently WikibaseQualityConstraints currently gets built on travis. Unfortunately it fails/errors on all builds.
Questions
- What values does the travis build bring us that we do not get from Jenkins (answer might possibly be the PHP matrix testing)? Depending on the answer decision could be taken to phase it out.
- which steps are required to make it green?
- notification channels (slack, irc) are configured but apparently do not reach us. Should we change that to our (todo) incident email?
