Review comment:
That gradle code shows you're familiar enough! mustRunAfter is a rare
case, really.
I sporadically use it to order certain tasks if they're queued together in
(possibly) parallel. An example: schedule integration tests to run after unit
tests have passed. Then you can run both separately (no dependency on each
other) but if you run them together (as part of check, which depends on both
integration and unit tests), unit tests will be executed prior to integration
tests.
