 * Haha this is fun :) The Kotlin gradle plugin triggers deprecation warnings for custom configurations (https://youtrack.jetbrains.com/issue/KT-60879)
 * We need to make DefaultConfiguration.isSpecialCaseOfChangingUsage think that our configurstion is a special case and not deprecated.
 * 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 :)
