Does cpd4sbt support multi project builds?

Does it support publish reports to sonarqube?

Hi,

Could you please guide me how we can publish cpd.xml to sonarqube?

Thanks in advance,
K.Sivakumar

How does it work

Hi, I just added the CPD plugin into one of my projects. Now, I am just wondering How does it work, I already have some duplicate code in my project but It never mentioned it in the CPD.xml. It was working fine with projects I was doing earlier.

Misleading readme.md

Hi,
I tried this plug-in and I like it.

But in order to modify the default settings for ReportTypeor OutputType I had to insert import de.johoop.cpd4sbt._ and to use e.g. ReportType.Simple / OutputType.Console instant of CPDReportType / CPDOutputType.

Is this intended or little error in the documentation? If this is an error, I would be glade to provide an fix.

Kind regards
Jentsch

Create a cross build for both 2.11 and 2.10

It would be nice if the plugin would work with both scala versions.

This can't be done right now... see http://stackoverflow.com/questions/23282469/does-sbt-builds-againts-scala-2-11

The setting name cpdOutputPath is wrong

I checked the source at src/main/scala/de/johoop/cpd4sbt/Settings.scala, found it should be cpdTargetPath instead of cpdOutputPath.

Support more cpd command line flags as settings

Like non-recursive, ignore-usings, skip blocks, failOnViolation, uri...

Does cpd4sbt support multiple languages on the same project?

In version 1.1.5 it was possible to add multi-language support by:

val cpdJava = TaskKey[Unit]("cpdJava", "CPD for java")

lazy val prj = (project in file("."))
  .settings(
     // ....
    // CPD for Scala sources
    CopyPasteDetector.cpdSettings,    
    cpdMinimumTokens := 75,
    cpdTargetPath := target.value,
    cpdReportName := "cpd-scala-report.xml",
    cpdLanguage := Language.Scala,

    // CPD for Java sources
    cpdJava <<= (cpdReportSettings, cpdSourceSettings, cpdMaxMemoryInMB, cpdClasspath, streams) map {
      (report, settings, mem, path, streams) => cpdAction(
        report.copy(name = "cpd-java-report.xml"),
        // TODO: remove or adjust minTokens.
        settings.copy(language = Language.Java, minTokens = 45),
        mem,
        path,
        streams
      )
    },

    // Run CPD for Java before CPD for Scala
    cpd <<= cpd dependsOn cpdJava,
   // ....
}

How it can be done in 1.2.0 ?

sbt-cpd pulls SNAPSHOT dependency for pmd-apex

Expected vs Actual Behaviour

It should...
not cause using projects to pull SNAPSHOT dependencies

Instead it...
it causes using projects to pull apex-jorje-ide-1.0-sfdc-187-SNAPSHOT-55042bfc2e

Steps to Reproduce

setup an sbt project and add

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

try to start an sbt session

[info] Resolved  dependencies
[warn] 
[warn]  Note: Unresolved dependencies path:
[error] sbt.librarymanagement.ResolveException: Error downloading apex:apex-jorje-semantic:1.0-sfdc-187-SNAPSHOT-55042bfc2e
...

Environment

• sbt version: 1.5.4
• Plugin version: 2.0.0
• Scala version(s): 2.11.11 and 2.12.12 (include all versions if cross-building)_
• Java version: 1.8
• Link to project source: n.a.

Error log when skipping duplicate files

Because of Issue #13, I have to specify the option to skip duplicate files:
cpdSkipDuplicateFiles := true

It seems to work, but my SBT console displays each time errors:
[error] Skipping /home/file.scala since it appears to be a duplicate file and --skip-duplicate-files is set.

This should not be an error: that's the expected behaviour, and not having a spam of red log messages.

Where is the version 1.2.0?

is it published?

CPD documentation link has expired

In readme.md (at line 30), the link for CPD documentation has expired and will get a 404 error.

It thinks whole file is duplicated

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")

Travis CI dropped

Given the poor handling of the recent security incident (https://arstechnica.com/information-technology/2021/09/travis-ci-flaw-exposed-secrets-for-thousands-of-open-source-projects/) I'm suspending Travis CI integration indefinitely.
