I'm checking my contributed plugins against travis-ci before releasing an update for Moodle 3.7
I'm experiencing build fails on travis-ci.org. The only changes to travis.yml are on moodle branches (added 37 branch) and php version (checks against 7.1 and 7.2). (my .travis.yml is attached).
Even when I restart previously successful builds, they fail too.
Builds for mysql fail with message
The command "mysql -u 'root' -h 'localhost' -e 'CREATE DATABASE `moodle` DE
FAULT CHARACTER SET UTF8 COLLATE utf8_general_ci;'" failed.
Exit Code: 1(General error)
