There are some breaking method changes in the 10.x.y versions and we're encountering exceptions when trying to run the flywayMigrate task thanks to those.
* Convert to gradle 7.
* More fixes, regenerated lockfiles.
* Update lockfiles for dependency update.
* Fix show_upgrade_diff for new lockfile format
* Add property for allowInsecureProtocol
Allow us to override the restriction against use of plain HTTP for
communication to dependency repositories. We need this to be able to use a
local proxy for dependency gathering.
* Checking in missing gradle.lockfile
