This plug-in generates trend report for SLOCCount and cloc open source tools, that count number of code lines written in many programming languages.


The SLOCCount plug-in scans for SLOCCount or cloc report files in the build workspace directory and reports the number of lines they found.

The following features are provided by this plug-in:

  • Parsing of reports generated by SLOCCount tool.
  • Parsing of reports generated by cloc tool.
  • Configuration of the files to scan after a build.
  • Trend reports showing the number of lines per language.
  • Trend reports showing the number of added or deleted lines per language.
  • Overview of the lines per file, folder or language.
  • Dashboard View portlet showing number of lines, files and languages per job.
  • Remote access API (REST API).
  • Works with any project/job type.

This plug-in is developed and maintained by Nicolas Piguet. Please use the Mailing Lists or issue tracker to ask questions, create feature request or bug reports, since I don't read the comment section on this page regularly.


If you are not sure which type of report files to use, prefer cloc. It is able to detect more programming languages than SLOCCount (Scala, Ant, CSS, ...) and is able to count also lines with comments that often contain Javadoc or Doxygen documentation. Cloc is also better portable, SLOCCount requires cygwin or similar environment under MS Windows.

Never switch between SLOCCount and cloc inside one job. You would end up with messy trend graph because they name programming languages differently. Delete all affected builds and rebuild the job in such case to fix the issue.


  • Install SLOCCount or cloc on the build slave machine. Note they may be present in package repository of your distribution.
    • Debian, Ubuntu, ...
      • apt-get install sloccount
      • apt-get install cloc
    • Red Hat, CentOS, Fedora, ...
      • yum install sloccount
      • yum install cloc
  • For each job configuration page:
    • Add a execute shell build step to generate the report files, or create them in your build scripts (Ant, Maven, Make, ...).
      • sloccount --duplicates --wide --details [source-folder] > [output-folder]/
      • cloc --by-file --xml --out=[output-folder]/cloc.xml [source-folder]
    • Activate the checkbox Publish SLOCCount analysis results and provide the path to the generated report files.



  • Download and install cloc (cloc.exe) on the build slave machine. Optionally if you have Perl installed, you can run cloc as a standalone Perl Script.
  • For each job configuration page:
    • Generate the report files
      • cloc.exe --by-file --xml --out=[output-folder]/cloc.xml [source-folder]
      • perl --by-file --xml --out=[output-folder]/cloc.xml [source-folder]
    • Activate the checkbox Publish SLOCCount analysis results and provide the path to the generated cloc report.


Since SLOCCount does not run on a native Windows machine the setup for Windows requires additional steps. Most of the setup is explained in detail in the SLOCCount documentation.

  • Install Cygwin on the build slave.
  • Compile and install SLOCCount within the Cygwin environment.
  • For each job configuration page:
    • Add a build step to run Cygwin and SLOCCount. See the ANT example below to learn how to start Cygwin and run SLOCCount from an ANT script.
      • /usr/bin/sloccount --duplicates --wide --details [source-folder] >[output-folder]/ You must convert Windows paths that are passed as parameters to SLOCCount utility to Linux/Cygwin style (C:\ becomes /cygdrive/c/).
    • Convert the SLOCCount results in back to windows paths.
    • Activate the checkbox Publish SLOCCount analysis results and provide the path to the generated SLOCCount report.

If you uses sloccount for multiple jobs sometimes two jobs end at the same time and sloccount is executed simultaneously. This will fail since SLOCCount (by default) uses one temp data folder in $HOME/.slocdata.

Either change sloccount to not use a temp data directory or change the setup explanation so novice users (like me) are explained to use the --datadir option in order to get a datadir per hudson job.

This seems to work: [ -d slocdata ] || mkdir slocdata sloccount --datadir slocdata --details "your source path" >

ANT example for Windows build

The target converts Windows paths to Linux style cygdrive paths (C:\ becomes /cygdrive/c/) before SLOCCount runs. The converted paths are passed as environment variables to Cygwin. After SLOCCount has been executed, the results in are converted back to windows paths.

ANT target

Add this target to your Jenkins build:


<target name="sloccount" depends="createAllSrc">
  <script language="javascript"> <![CDATA[
    function winToCygdrivePath(cygProp, winProp) {
      winPath = project.getProperty(winProp);
      cygPath = winPath.replaceAll("C:", "/cygdrive/c").replace('\\', '/');
      project.setProperty(cygProp, cygPath);
    winToCygdrivePath("cygdrive.workspace.dir", "dir.workspace");
    winToCygdrivePath("cygdrive.allsrc.dir", "dir.allsrc");
    winToCygdrivePath("", "");

  <exec executable="${cygwin.bin}\bash.exe">
    <arg line="-li '${}/'" />
    <env key="SLOCCOUNT_SOURCE_DIR" value="${cygdrive.allsrc.dir}" />
    <env key="SLOCCOUNT_OUTPUT_DIR" value="${cygdrive.workspace.dir}" />

  <replace file="${dir.workspace}/" token="/cygdrive/c" value="C:" />
  <replace file="${dir.workspace}/" token="/" value="\" />

You may have to adjust the paths used in the snippet, if your Jenkins workspace is on another drive than C.

Shell script

This shell script is called by Cygwin / ANT.

sloccount --duplicates --wide --details "$SLOCCOUNT_SOURCE_DIR" > "$SLOCCOUNT_OUTPUT_DIR/"

Support for cloc tool

Parsing of cloc XML reports is supported natively in the plugin from version 1.20.

Cloc (Count Lines of Code) is a tool similar to SLOCCount. It provides output to a XML file that can be simply transformed to the SLOCCount format and used in this plugin. Cloc is written in Perl and should be better portable than SLOCCount.

This howto was created and tested on Debian GNU/Linux, Jenkins 1.447, SLOCCount plugin 1.12, cloc 1.60 and xsltproc 1.1.28.

Install cloc and xsltproc

Download cloc from and install it. You need also a whatever tool for XML transformations (xsltproc used) or you can try clokins tool (not tested at all). You can install the packages present in your GNU/Linux distribution.

# Debian/Ubuntu specific
apt-get install cloc xsltproc

Script for XSLT transformation

Copy-paste the script below and store it to cloc2sloccount.xsl file accessible by your Jenkins server. If you are using master and slave machines, store the script to all slaves where the jobs are executed.


<xsl:stylesheet version="1.0" xmlns:de="." xmlns:xsl="">
<xsl:output method="text" version="4.0" encoding="iso-8859-1"
  doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN"

<xsl:template match="file">
  <xsl:variable name="file_path" select="translate(@name,'\\','/')"/>
  <xsl:variable name="file_path_part1" select="substring-after($file_path,'/')"/>
  <xsl:variable name="module" select="substring-before($file_path_part1,'/')"/>
  <xsl:value-of select="@code"/>
  <xsl:value-of select="@language"/>
  <xsl:value-of select="$module"/>
  <xsl:value-of select="@name"/>

<xsl:template match="files">
<xsl:apply-templates select="file"/>

<xsl:template match="cloc_url">For more details see: <xsl:value-of select="."/>

<xsl:template match="cloc_version">This report has been generated by cloc <xsl:value-of select="."/>.<xsl:text>&#13;&#10;</xsl:text>

<xsl:template match="header">
<xsl:apply-templates select="cloc_version"/>
<xsl:apply-templates select="cloc_url"/>

<xsl:template match="results">
<xsl:apply-templates select="header"/>
<xsl:apply-templates select="files"/>

<xsl:template match="/">
<xsl:apply-templates select="results"/>


Execute cloc

Change configuration of your job to execute the following shell script. Update the path to the directory where your source files are stored and optionally pass additional parameters to cloc. Then execute XSLT transformation on cloc output to get a SLOCCount compatible report.

cloc --by-file --xml -out=cloc.xml DIRECTORY
xsltproc PATH/TO/cloc2sloccount.xsl cloc.xml >

Enable SLOCCount publisher, enter path to the generated SLOCCount report and that's all.

Using the plugin within a Jenkins pipeline

Configure your pipeline in a similar way to this example:


node('master') {
    stage ("Analyse") {
        sh 'sloccount --duplicates --wide --details path-to-code/ >'
    stage ("Publish reports") {
        sloccountPublish encoding: '', pattern: ''
