{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Slices don't differentiate between (*) and (**) making top-level cycle checks impossible","articleBody":"if I understand the original docs of ArchUnit correctly, there should be a difference between (*) and (**).\n\n- (*) should target the package\n- (**) should target the package and its sub packages\n\nSee also https://www.archunit.org/userguide/html/000_Index.html#_slices\n\nthis is however not how the dotnet port of ArchUnit behaves.\n\nIf I specify sth. like CycleDemo.(*) I'd expect it to only check cycles on the top-level\n\nso \n\n- Domain -\u003e Db -\u003e Domain should be detected\n- Domain.Beers -\u003e Domain.Wine -\u003e Domain.Beers should **not** be detected\n\nit will detect however both cycles effectively behaving like (**)\n\n```\n\"Slices matching \"CycleDemo.(*)\" should be free of cycles\" failed:\n\tCycle found:\nDb -\u003e Domain\n\tCycleDemo.Db.ViolatingRepository -\u003e CycleDemo.Domain.Service\nDomain -\u003e Db\n\tCycleDemo.Domain.Service -\u003e CycleDemo.Db.Repository\n\n\tCycle found:\nDomain.Beers -\u003e Domain.Wines\n\tCycleDemo.Domain.Beers.Beer -\u003e CycleDemo.Domain.Wines.Wine\nDomain.Wines -\u003e Domain.Beers\n\tCycleDemo.Domain.Wines.Wine -\u003e CycleDemo.Domain.Beers.Beer\n```\n\nI compared it with the behavior of the Java implementation and it works as documented.\n\n```\nArchitecture Violation [Priority: MEDIUM] - Rule 'slices matching 'demo.(*)' should be free of cycles' was violated (1 times):\nCycle detected: Slice db -\u003e \n                Slice domain -\u003e \n                Slice db\n  1.
