Hi Sriram,

run Ant with the -debug option and you should get an detailed stack trace.

Hi Marc,

Unfortunately, there are not any details for the failure.

Below is the total error that I got...
**************

Buildfile: D:\ANT\WS\ANTProj\build.xml
report:
[jacoco:report] Loading execution data file
D:\ANT\CodeCoverage\jacoco\jacoco_PS3_WLS1.exec

BUILD FAILED
D:\ANT\WS\ANTProj\build.xml:25: Error while creating report

Total time: 1 second
**************

In this case, I have pointed to the directory where jar files are
located. But when I picked one the jars, expanded it and pointed to
that directory, which contained classes, it worked fine. Below is the
code snippet.
******************************

    <structure name="Finally code coverage Report">
        <classfiles>
            <fileset dir="${classes.dir}" />
        </classfiles>
        <sourcefiles encoding="UTF-8">
            <fileset dir="${src.dir}"/>
        </sourcefiles>

    </structure>
*******************************

When I googled also, it is mentioned that jars will be automatically
taken care of, but this is not working for me and Iam not sure where
Iam going wrong or missing something here.

Just check the above code snippets and let me know if Iam doing
something wrong.
Thanks!

Always B Happy ,
Sri Ram

Hi Sriram,

JaCoCo should be fine with JAR files, it will automatically read
classe files from it. Works even recursively e.g for JAR files in
WAR files.

To help you it would be useful to see the full error message. There
should be more text after "Error while creating report" with the
exact technical details.

Hi Marc,

As you mentioned, I have used Jacoco.exec and the class files of
our product. Coverage Report is successfully generated. But for
this, I needed to extract the jars and unzip them and point to
that folder. But, in our installation, we only have jar files and
class files are not visible, unless we explicitly unzip them.

I tried to include jars but, I always get an error "Error while
creating report"

Is there a way that I can generated Code coverage reports for jars
but not classes?  Iam adding my target code for your convenience.

***********************************************
<target name="report">
<mkdir dir="${jacoco.report.dir}"/>
<jacoco:report>
<executiondata>
<file file="${jacocoexec.fullpath}"/>
</executiondata>
<structure name="Code
coverage Report">
<classfiles>
<fileset dir="${classes.dir}" />
</classfiles>
<sourcefiles encoding="UTF-8">
<fileset file="${src.dir}/*.jar"/>
</sourcefiles>
</structure>
<html
destdir="${jacoco.report.dir}"/>
<csv destfile="${jacoco.report.dir}/report.csv"/>
<xml destfile="${jacoco.report.dir}/report.xml"/>
</jacoco:report>
</target>
*************************************************
Thanks already,

Always B happy,
Sriram
