If you want to actually view the library dependencies (as you would with Maven) rather than the task dependencies (which is what inspect tree displays), then you’ll want to use the sbt-dependency-graph plugin.
Add the following to your project/plugins.sbt (or the global plugins.sbt).
addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.9.2")
Then you have access to the dependencyTree command, and others.
