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"
