Hi JK, pre-requsites:
downloa *jacoco-0.8.3.zip <http://search.maven.org/remotecontent?filepath=org/jacoco/jacoco/0.8.3/jacoco-0.8.3.zip>* *0.8.3 <https://github.com/jacoco/jacoco/tree/v0.8.3>* 2019/01/23 3.7 MB d4f07cb98bbf2305dbd16ee3012d7321 extract and navigate to lib directory, jacococli.jar will be there in lib dir. The most important thing while generating HTML report from the *.exec file is providing correct src and class files path so exec file can map the consumption of code and give you report HTML. for that you run like below command: java -jar <path to jacoco directory>/lib/jacococli.jar report <exec file path> --classfiles <TOMCAT_HOME>/webapps/dummy/WEB-INF/classes/ --sourcefiles /opt/dummy/web-inf/classes/ --html /tmp/report run command like above. you will get html report for sure.
