I have chosen a delinquent Java package to work fix. But I need some help understanding
what's going on. Groovy is failing to build because it depends on gradle-local which
doesn't exist. But gradle-local did exist at one time because groovy was successfully
build with it on 2019-07-30. So, where did gradle-local go? Why has it disappeared? I
guess the important question is how can I get it back?
