SBT-dependency tree

In this blog , I am going to describe how to view sbt dependency tree.  Last week I had a problem related to different cross version of a dependency. I knew the problem cause but  I had spent a day to know which dependency had brought that cross version of dependency. I did some study and browsing about that problem then I come across a sbt plugins as a potential solution of that problem.
In a project there is a chance of using same library but different version by multiple dependencies.  I also victim of dependency version conflict.  The good way is just draw a sbt dependency tree. Here is a sbt-plugin sbt-dependency graph is available for that.

Following are the steps to install and use sbt-dependency-graph
a) add plugin to project/plugins.sbt

addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.7.4")

b) add sbt setting in build.sbt


if project is multi module then add to Parent.scala:

object Parent extends Build{
lazy val parent = Project(id="parent", base=file(".")).settings(net.virtualvoid.sbt.graph.Plugin.graphSettings: _*)

Now run sbt commond:

$ sbt dependency-tree

$ sbt dependency-graph

or provide lot of options.for more info sbt-dependency-graph

Enjoy with  sbt  projects !!!
