Hi JK,
I need some inputs from you.
steps:
1. Startup your tomcat/container and perform some operations on a web
application so some of the class files consumed by some random operation
like login etc.
2. Shutdown tomcat gracefully - /<tomcat server dir>/bin/shutdown.sh/bat
etc.
3. now verify the size of generated jacoco.exec file in your case <
JACOCO_EXEC_FILE>
Now run "java -jar jacoco/lib/jacococli.jar report JACOCO_EXEC_FILE
--classfiles ~/1/ --html report" command
some more input like below:
while running above command what you are getting in the console I mean how
many class files getting consumed.
[INFO] Loading execution data file JACOCO_EXEC_FILE.
[INFO] Analyzing <????> classes.
how many class files ?? and if possible share your exec file that would be
great to solve the issue.
Thanks,
Jitendra
