Hi,
thanks for the stack trace! The trace indicates that
"E:\test\jacoco.exec" is not a valid execution data file or it has been
corrupted somehow.
If you can provide this file I can have a look what the issue is. You
can also inspect the file yourself using our code example here:
http://www.eclemma.org/jacoco/trunk/doc/examples/java/ExecDump.java

Can we copy jacoco.exec ( execution data file) generated on linux to Windows
and use it as input for merge ANT target? We are getting cannot read
file(execution data file copied from linux) error while merge. Is there any way
to fix this? More details below...
We want to merge execution data files generated on different envs (one generated on Linux
for selenium and other generated on Windows for jUnits) to get a combined coverage
report. We are using ANT, "jacoco:merge" is being run on Windows. We have
copied jacoco.exec from Linux to Windows and trying to merge the files.

Below is my ANT target. In this mod1 jacoco.exec file was copied from a linux
box and mod2 jacoco.exec files were generated on same windows m/c where merge
target is run.
<target name="merge-all-modules">
<jacoco:merge destfile="${mytest.dir}/target/merged.exec">
<fileset dir="${mytest.dir}/target/mod2"
