It thinks whole file is duplicated

[hwzhao]

When I integrate the cpd4sbt 1.2.0, I got the result like

<?xml version="1.0" encoding="utf-8"?>
<pmd-cpd>
   <duplication lines="408" tokens="2626">
      <file line="1" path="D:\program\rrx\app\services\WechatService.scala"/>
      <file line="1" path="D:\program\rrx\app\services\WechatService.scala"/>
      <codefragment><![CDATA[package services
import java.security.MessageDigest
...

It seems whole file is duplicated, and there are all my scala files in the xml file. build.sbt:

lazy val root = (project in file(".")).enablePlugins(PlayScala, CopyPasteDetector, BuildInfoPlugin).
  settings(
    buildInfoKeys := Seq[BuildInfoKey](name, version, scalaVersion, sbtVersion),
    buildInfoPackage := "tool"
  )

plugins.sbt

addSbtPlugin("com.eed3si9n" % "sbt-buildinfo" % "0.6.1")
addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "4.0.0")

addSbtPlugin("de.johoop" % "cpd4sbt" % "1.2.0")
addSbtPlugin("org.scalastyle" %% "scalastyle-sbt-plugin" % "0.8.0")

Same problem here

I am seeing this problem in sbt-cpd 2.0.0 as well. Files are being compared with themselves. This is what I added to plugins.sbt:

addSbtPlugin("com.github.sbt" % "sbt-cpd" % "2.0.0")

while #19 is not merged and release, you can add to your settings as a workaround

CpdKeys.cpdSourceDirectories in Compile := (CpdKeys.cpdSourceDirectories in Compile).value.distinct

@jtjeferreira add to settings where?

@jtjeferreira add to settings where?

you must add that line to your project settings. For example if you use build.sbt add that line to the file...

[keith-coursera]

@jtjeferreira adding that line to build.sbt gives an error

error: not found: value CpdKeys
CpdKeys.cpdSourceDirectories in Compile := (CpdKeys.cpdSourceDirectories in Compile).value.distinct
^
[error] Type error in expression

[jtjeferreira]

@keith-coursera you have to import com.github.sbt.cpd.CpdKeys
