Arcan is a Java software analysis tool, supporting the detection of architectural smells. Currently, it supports the following three architectural smells (AS):

  • Unstable Dependency: describes a subsystem (component) that depends on other subsystems that are less stable than itself. Subsystems affected by this may cause a ripple effect of changes in the system .
  • Hub-Like Dependency: this smell arises when an abstraction has (outgoing and ingoing) dependencies with a large number of other abstractions.
  • Cyclic Dependency: refers to a subsystem (component) that is involved in a chain of relations that break the desirable acyclic nature of a subsystems dependency structure. The subsystems involved in a dependency cycle can be hardly released, maintained or reused in isolation.
