Ok, here is the problem: If you configure a custim exclclassloader
please make sure to also exclude sun.reflect.DelegatingClassLoader
(which is the default value), otherwise reflection will not work. so
your coverage tag should read:
exclclassloader="sun.reflect.DelegatingClassLoader:javassist.Loader"
See documentation: http://eclemma.org/jacoco/trunk/doc/agent.html

Hi All,
I am running code coverage using Jacoco, and getting error "Unable to read
execution data file - reports\jacoco.exec"
OS - Windows7
JDK - 1.6 / (I tried with JDK 1.7 as well)
Jacoco - latest Jars
Below is the task definition
<jacoco:coverage destfile="reports/jacoco.exec"
exclclassloader="javassist.Loader">
<junit printsummary="yes" haltonfailure="yes" fork="yes"
showoutput="yes">

<fileset dir="${slib.dir}">
<include name="**/*.jar" />
</fileset>
</classpath>
<batchtest fork="no" todir="reports">
<fileset dir="test">
<include name="**/*Test*.java"/>
</fileset>
</batchtest>
</junit>
</jacoco:coverage>
<jacoco:report>

</sourcefiles>
</structure>
<html destdir="reports"/>
<csv destfile="reports/report.csv"/>
<xml destfile="reports/report.xml"/>
</jacoco:report>
</target>
If I keep "batchtest fork="no"" - Jacoco executes the Test cases successfully -
But Does not generate jacoco.exec file. Can someone help to identify - Why is not generating the
jacoco.exec file?
If I keep "batchtest fork="yes/true"" - Jacoco generates jacoco.exec file, but all the
test cases fail saying "Class not found sun/reflect/GeneratorAccessorMethod".
Please let me know if more information is required.
Hi Marc,
Thanks for response, sorry for late reply.
We have
1. Jacoco 0.7.5
2. JDK 1.6.29 (Also Tried with JDK 1.7)
3. Stack Trace when 'fork='yes' in batchtest target
