- * Haha this is fun :) The Kotlin gradle plugin triggers deprecation warnings for custom configurations (https://youtrack.jetbrains.com/issue/KT-60879)

- * We do this by setting DefaultConfiguration.roleAtCreation to LEGACY, thus isInLegacyRole will now return true.
- *
- * Yeah I know we can just ignore the deprecation warning, but doing so wouldn't alert us to issues when testing against pre-release Gradle versions. Also this is more fun :)
