The Question: how do I know which sbt plugins are being brought in by this other sbt plugin in my build?

This is something that comes up infrequently enough for me that I always remember it’s possible but infuriatingly can NEVER remember how to do it. It’s also really difficult to search for, so I spend a while feeling very frustrated with sbt, the sbt plugin that has made me ask the question, and myself.

I’m writing it down here in the hopes that I will remember I wrote it down, and have just one place on the internet to search!

The Steps:

1. In an sbt console, run reload plugins to get into the root project’s project/ build definition.
2. Once in the project build, you can run a lot of your usual commands. For this particular problem, I run dependencyBrowseTree (from sbt-dependency-tree which I have defined as a global plugin) to open a searchable tree of all project dependencies.
3. Once finished, reload return switches you back to the original build.

Pretty straightforward, just difficult to remember!
