sbt-dependency-graph

Visualize your project's dependencies.

Preliminaries

Starting with version 0.8.0, the plugin will only work for projects that use sbt 0.13.x. See the 0.7 branch for older versions that still work with sbt < 0.13.

How To Use

Since sbt-dependency-graph is an informational tool rather than one that changes your build, you will more than likely wish to install it as a global plugin so that you can use it in any SBT project without the need to explicitly add it to each one. To do this, add the plugin dependency to ~/.sbt/0.13/plugins/plugins.sbt:

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

To add the plugin only to a single project, put this line into project/plugins.sbt of your project, instead.

This plugin is an auto-plugin which will be automatically enabled starting from sbt 0.13.5. See the compatibility notes when using this plugin with sbt < 0.13.6.

Main Tasks

• dependencyTree: Shows an ASCII tree representation of the project's dependencies
• dependencyBrowseGraph: Opens a browser window with a visualization of the dependency graph (courtesy of graphlib-dot + dagre-d3).
• dependencyGraph: Shows an ASCII graph of the project's dependencies on the sbt console
• whatDependsOn <organization> <module> <revision>: Find out what depends on an artifact. Shows a reverse dependency tree for the selected module.
• dependencyLicenseInfo: show dependencies grouped by declared license
• dependencyGraphMl: Generates a .graphml file with the project's dependencies to target/dependencies-<config>.graphml. Use e.g. yEd to format the graph to your needs.
• dependencyDot: Generates a .dot file with the project's dependencies to target/dependencies-<config>.dot. Use graphviz to render it to your preferred graphic format.
• ivyReport: let's ivy generate the resolution report for you project. Use show ivyReport for the filename of the generated report

All tasks can be scoped to a configuration to get the report for a specific configuration. test:dependencyGraph, for example, prints the dependencies in the test configuration. If you don't specify any configuration, compile is assumed as usual.

Configuration settings

• filterScalaLibrary: Defines if the scala library should be excluded from the output of the dependency-* functions. If true, instead of showing the dependency "[S]" is appended to the artifact name. Set to false if you want the scala-library dependency to appear in the output. (default: true)
• dependencyGraphMLFile: a setting which allows configuring the output path of dependency-graph-ml.
• dependencyDotFile: a setting which allows configuring the output path of dependency-dot.
• dependencyDotHeader: a setting to customize the header of the dot file (e.g. to set your preferred node shapes).
• dependencyDotNodeLabel: defines the format of a node label (default set to [organisation]<BR/><B>[name]</B><BR/>[version])

E.g. in build.sbt you can change configuration settings like this:

filterScalaLibrary := false // include scala library in output

dependencyDotFile := file("dependencies.dot") //render dot file to `./dependencies.dot`

Known issues

• #19: There's an unfixed bug with graph generation for particular layouts. Workaround: Use dependency-tree instead of dependency-graph.
• #39: When using sbt-dependency-graph with sbt < 0.13.6.

Compatibility notes

• sbt < 0.13.6: fallback on the old ivy report XML backend which suffers from #39
• sbt < 0.13.5: no autoplugin support, you need to add

net.virtualvoid.sbt.graph.DependencyGraphSettings.graphSettings

to your build.sbt or (~/.sbt/0.13/user.sbt for global configuration) to enable the plugin.
