Copy & Paste Detector plugin using PMD for sbt.

sbt-cpd - Copy & Paste Detection using PMD/CPD for sbt

Build Status Codacy Grade sbt 0.13 version sbt 1.0 version pmd version

This is an sbt plugin for duplicate code detection using Copy/Paste Detector (CPD) from the PMD project.

Install the plugin by adding the following to project/plugins.sbt:

addSbtPlugin("com.github.sbt" % "sbt-cpd" % "<version>")

And then execute the plugin with sbt cpd. This will scan your source code under src/main/scala and output a report containing the duplicates to target/scala-2.xx/cpd/cpd.xml.
