0 % shown in the code coverage

[leoy...@gmail.com]

Hi,
I am having problem to generate a coverage report when running tomcat with jacoco.
I have set up tomcat to run with the jacoco agent with this param: -javaagent:/Users/leo_chan/dev/jacoco/lib/jacocoagent.jar=output=tcpserver,address=*,port=6300,dumponexit=false,append=false,..."

Then I used maven to kick of a testng test that hit a url which will in return invoke my controller running in tomcat. Then maven task will dump the exec file and generate the report. I can see that exec file is generated and but the final report snow 0 of 0 coverage. On the sessions report page, it does show my controller class in the "Execution data for the following classes is considered in this report:" section.
Class Id
....accessservice.controller.HeartbeatController cac6fb3c4204f6d9


But the main report only shows:
Element Missed Instructions Cov. Missed Branches Cov.
Total 0 of 0 n/a 0 of 0 n/a

I check the target/classes folder and check the controller class is the same one used in tomcat. Why is the report shows 0 coverage? What am I missing?

One thing is that the exec file doesn't seem to have a lot of information:
??MacBook-Pro.local-9822958fLqb?TLqcm???<B??=com/.../nsp/accessservice/controller/HeartbeatController??MacBook-Pro.local-224c5111Lqle?Lqlܙ???<B??=com/.../nsp/accessservice/controller/HeartbeatController??

Thanks for your help.

Hi Leo,

on the Sessions page, is the class HeartbeatController linked to the
report or is it just plain text?

If it is not linked this means the JaCoCo agent sees a different class
file than the one used for report generation.

BTW, the exec file is a internal binary format. You can open exec files
with the EclEmma plugin or dump the content with this example program:

Hi Mac,

  Thanks for the reply.  Yes the class in the report is plain text.  I actually use the classdumpdir option in the agent start up to dump the HeartBeatController class file and then put that into the target/classes folder to make sure it is the same class but still get the same result.  I also do a diff on the heartBeatController class to the one in tomcat, it is the same.    It there a way that I can make sure I am using the right one beside what I just did?

Hi Leo,

if it is not linked this means the class file used at runtime is
different from the class file used at reporting time.

If already use the classdumpdir option I can't really see what's going
wrong. There is a another utility in our examples which shows the id of
given class file. This might help to track where the difference comes
in:

Hi Marc,

   I figured out the problem.  It turns out it is an pom.xml issue.  In the report-integration goal.  I think my includes option is wrong.  I took that out and the generated report show coverage and link now.  Thanks for your help.

Hi Marc,

   One follow up question.  Is there a way to tell maven to look into a war file instead of the target/classes directory for classes when generating the report? 

[Marc Hoffmann]

Ciao Leo,

JaCoCo core processes archive files recursively. The maven plugin
processes all files from the build output directory. If you configure
the build output to the location of your WAR file JaCoCo should pick it
up here.

For details maybe our Maven wizards can jump in here?

Regards,
-marc
