/**
 * Test Gradle performance against it's own build.
 *
 * Reasons for re-baselining:
 * - accept a regression in Gradle itself
 * - accept a regression in the Gradle build
 * - improvements to Gradle or its build!
 *
 * Reasons for breaking:
 *   - e.g. change in Gradle that breaks the Gradle build
