How to find unused sbt dependencies?

Question

My build.sbt has a lot of dependencies now. How do I know which dependencies are actually being used?

Maven seems to have dependency:analyse http://maven.apache.org/plugins/maven-dependency-plugin/ Is there something similar for sbt?

Answer 1

There is the sbt-explicit-dependencies plugin, which has been developed recently. It has direct commands in the SBT console to:

• Enforce explicit direct declaration of dependencies, thus disallowing transitive dependencies.
• Detect and remove unneeded dependencies.
