Migration from version 1.X

• moduleLayers are now removed in favour of allowed syntax.
  • Example of migration: moduleLayers = [":feature:\\S*", ":lib\\S*", ":core\\S*"] -> allowed = [":feature:\\S* -> :lib\\S*", ":feature:\\S* -> :core\\S*", :lib\\S* -> :core\\S*"]
• assertModuleLayers doesn't exist anymore - assertAllowedModuleDependencies exists instead
• Parameter modules.graph.print.statistics is removed - use task generateModulesGraphStatistics instead
