I want to get a code coverage report (or tracking controller flow of an application) when I execute the some scenario on live application i.e. while application running in server, so I have refereed the official Jacoco documentation and did as fallows

As a first step, I tried to bind the jacoco agent to the application running port

export MAVEN_OPTS=-javaagent:/home/user/.m2/repository/org/jacoco/org.jacoco.agent/0.7.4.201502262128/org.jacoco.agent-0.7.4.201502262128-runtime.jar=includes=*,output=tcpserver,port=6300,address=*,dumponexit=true

then I have started the server and executed some test scenarios by that time I have also requested jacoco to get the dump by executing following command

mvn jacoco:dump

when I executed the above command first it showed like java.net.BindException: Address already in use then it printed as fallows

[INFO] Connecting to localhost/127.0.0.1:6300

When I stopped the server jacoco.exec has been generated to a known location there after I have requested to generate a jacoco report by executing the following command

mvn jacoco:report

Finally I got the report but when I open the index.html page it showed 0% coverage.

Please help me to get the code coverage report and any help will be appreciated.
