This SBT plug-in enables you to analyze your code with the help of the great PMD Copy/Paste Detector tool. It defines a cpd sbt action for that purpose.

For SBT 0.13, you've basically got to add the following to your project's build.sbt file:

import de.johoop.cpd4sbt.CopyPasteDetector._

cpdSettings

Also, you have to add the plugin dependency to your project's ./project/plugins.sbt or the global .sbt/project/build.sbt:

addSbtPlugin("de.johoop" % "cpd4sbt" % "1.1.5")

The settings specified below are still mostly valid, but they're now specified using the new settings system of SBT 0.13.

• 1.1.5
  • Added settings for the CPD command line switches ignore-annotations, ignore-literals, ignore-identifiers, skip-duplicate-files and skip-lexical-errors
  • Added cs and plsql languages (and fixed a typo)
  • Added option to print the CPD report to the console

(see also the CPD documentation)
