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.
