What I want to do:
Provide a code coverage report for the server's code that is running on AWS windows 2k12 server.
What I did:
Result:
Got error unable to read execution data file C:/path/to/exec/jacoco.exec
Build.xml:
<project name="Example" default="rebuild" xmlns:jacoco="antlib:org.jacoco.ant">

</classfiles>

</sourcefiles>
</structure>
<!-- to produce reports in different formats. -->
<html destdir="${result.report.dir}" />
<csv destfile="${result.report.dir}/report.csv" />
<xml destfile="${result.report.dir}/report.xml" />
</jacoco:report>
</target>
I am not sure if the problem is with exec file (it is corrupted maybe) or is with my entire setup. Any help to identify and help solving the problem is appreciated!!!
Thanks!

Why does the coverage report not show highlighted source code? Make sure the following prerequisites are fulfilled to get source code highlighting in JaCoCo coverage reports: Class files must be compiled with debug information to contain line numbers. Source files must be properly supplied at report generation time.
JaCoCo comes with Ant tasks to launch Java programs with execution recording and for creating coverage reports from the recorded data. Execution data can be collected and managed with the tasks coverage , agent , dump and merge . Reports in different formats are created with the report task.
JaCoCo reports help us visually analyze code coverage by using diamonds with colors for branches, and background colors for lines: Red diamond means that no branches have been exercised during the test phase. Yellow diamond shows that the code is partially covered – some branches have not been exercised.
I got this when using gradle and jaCoCo.
I deleted the build/ directory and reran ./gradlew jacocoTestReport, this time passing.

Similar to @sofia's solution but for gradle: I removed the version after tool version. Instead of
allprojects {
jacoco {
toolVersion = '0.7.1.201405082137'
}
}
I used the following
allprojects {
jacoco {
toolVersion = '0.7.1'
}
}
