Build a Scala package dependency graph

Question

My scala (Activator + Play) project starts getting huge. I want to split it into multiple small packages. However, as a starting point I need to know which file/package depends on which file/package!

How can I obtain a tree or a graph of dependencies among my files?

I tried sbt-dependendy-graph but it gives external dependencies...

Any clue?

A project indended to do it but it seems no longer maintained: https://github.com/dwijnand/sbt-project-graph You could consider migrating it to your Scala version. — Alban Dericbourg, Nov 30 '16 at 15:37
@AlbanDericbourg this plugin is for _inter-project_ dependencies, not for packages/files dependencies. — laughedelic, Nov 30 '16 at 19:17
Just to clarify, do you want something similar to Haskell's [graphmod](https://github.com/yav/graphmod/wiki) but for Scala? — aij, Jul 06 '18 at 15:01
@aij yes, quite like that! Dependencies between modules/classes/files within the same project. — Nicolas Cailloux, Jul 17 '18 at 13:09

The closest thing I know is acyclic, which lets you enforce that the package dependency graph is acyclic. There's already an issue asking for a way of visualizing the dependency graph. Looking at the code, it should be easy to build something like what you want, check DependencyExtraction.scala and GraphAnalysis.scala
