Code coverage for Manual Regression using sonar and jacoco - ant

Question

I am trying to generate code coverage for webapp for manual testing using jacoco and sonar.
I am able to generate jacoco.exec file by modifying the catalina.bat in following way:
SET JACOCO=-javaagent:\jacoco-0.7.5.201505241946\lib\jacocoagent.jar=destfile=C:\jacoco.exec,append=true,includes=*
set JAVA_OPTS=%JAVA_OPTS% %JACOCO%
I then copy the jacoco.exec file to a target folder inside sonarcube and run ant sonar. The build.xml has following entries:
<!-- The following properties are required to use JaCoCo: -->
<property name="sonar.dynamicAnalysis" value="reuseReports" />
<property name="sonar.java.coveragePlugin" value="jacoco" />
<property name="sonar.jacoco.reportPath" value="target/jacoco.exec" />
<!-- Define the SonarQube target -->
<target name="sonar">
<taskdef uri="antlib:org.sonar.ant" resource="org/sonar/ant/antlib.xml">
<!-- Update the following line, or put the "sonar-ant-task-*.jar" file in your "$HOME/.ant/lib" folder -->
<classpath path="../apache-ant-1.9.6/lib/sonar-ant-task-2.3.jar"/>
</taskdef>
<!-- Execute the SonarQube analysis -->
<sonar:sonar/>
</target>
</project>
The output I get from ant if following. I don't see any coverage in the report at the url
http://localhost:9000/dashboard/index/org.codehaus.sonar:example-java-ant
Am I missing something?

Answer 1

Looking at log of analysis we cannot see any JaCoCo sensor executed. JaCoCo sensor is executed only if you have java file in your analysis which you don't as you can see per 0 files indexed line in your log.
To explain this behaviour you have to understand that JaCoCo sensor will only report coverage on files indexed so if there are no java files, there is no point to execute it.
So to report and compute coverage you would have to import a coverage report related to some source files you analyze in your project.
