How I can list all sbt dependencies?

In case the dependency hierarchy provided by sbt-dependency-graph is not needed, the following might be useful:

sbt 'show dependencyClasspathFiles'

There is a nice sbt plugin for that: https://github.com/jrudolph/sbt-dependency-graph

Simply adding to ~/.sbt/0.13/plugins/plugins.sbt:

addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.8.0")

Calling sbt dependencyTree you can get an "ascii graph" like:
