Some hints:

- Are you executing on windows (backslash)? I would use regular slash in any case. - also the exclude is given relative to the basedir. So I would write name="a1.jar" only
- The JAR file is sitting directly under classes dir?

To test the fileset you can e.g. use it as source within a simple copy task.

Hi Marc,

This is the code snippet that Iam using to exclude certain jars but
they dont seem to be exluded and causing the task to fail. Can you
tell me where Iam going wrong?

    <structure name="Finally code coverage Report">

Hi Marc,

Iam not pretty sure but It seems they are 3rd party jars and dont
have access permissions to analyze them. Will update once I get a
confirmation on this.
I will try with the update that you have provided.
Thank you.

Hi Sri Ram,

this is a regular Ant fileset. See Ant documentation how to
configure includes/excludes correctly:

https://ant.apache.org/manual/Types/fileset.html [1]

Just curious: What was causing the failure? We're always interested
in potential bugs in JaCoCo.

Hi Marc,

Thanks!
As per your suggestion, I have run ant with debug option and
identified that there are some problematic jars due to which the job
was failing. I manually deleted them from the folder and ran the
task
and it was successful.

Now, I want to exclude them from the program as it is not possible
to
remove them from actual test environment.

I have tried <exclude name="abc.jar"/> and <excludefiles
name="abc.jar"/> but both dont seem to work.

Any suggestions here?
Thanks in advance!

Hi Sriram,

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

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!

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,
