I liked the package design (later renamed to file design) feature in SonarQube to detect cycles inside my application. See this old blog post:

In the recent 6.0 version of SonarQube I can't find this anymore, there is a design plugin but that only seems to be supported until version 4.5.6. Am I overlooking something or is the file design feature just gone?
Design-related services were dropped in version 5.2.
