Thanks Evgeny for your reply. Please help with below queries, Here is my requirement and want to generate report by merging the two different runs on two different hosts
Run1 on Host1: -> -javaagent:/u01/jacoco/lib/jacocoagent.jar=destfile=/u01/jacoco/dump/jacoco.exec,classdumpdir=/u01/jacoco/dump/class,output=file,address=,includes=apps.applcore.* - > Class files dumped for tests DescriptiveFlexfieldTag.2419d92cd2c6a871.class and ConvertNumberTag.37bfad455e453d93.class Run 2 on Host2 : -> -javaagent:/u01/jacoco/lib/jacocoagent.jar=destfile=/u01/jacoco/dump/jacoco.exec,classdumpdir=/u01/jacoco/dump/class,output=file,address=,includes=apps.applcore.* - > Class files dumped for tests DescriptiveFlexfieldTag.49dc0cd2912591ec.class and ConvertNumberTag.d7c0cf501f15a429.class I merged multiple exec files collected from HOST and HOST2 into a new one using java -jar jacococli.jar merge Now when I try to generate report using below command, I'm getting "Can not have same class" issue. java -jar jacococli.jar report /scratch/jacoco/dump/jacoco/dest/merged.exec /scratch/dump/jacoco.exec --classfiles "/scratc/jacoco/dump1/jacoco/classes/" --classfiles <classes from HOST1> --classfiles <classes from HOST2> --csv /scratch/final_report/mycsv.csv --html /scratch/final_report --name "Code Coverage" Hence I removed or excluded classes from HOST2 and generating report using below command, java -jar jacococli.jar report /scratch/jacoco/dump/jacoco/dest/merged.exec /scratch/dump/jacoco.exec --classfiles "/scratc/jacoco/dump1/jacoco/classes/" --classfiles <classes from HOST1> --csv /scratch/final_report/mycsv.csv --html /scratch/final_report --name "Code Coverage" My query is, - Will I be able to still achieve the right code coverage? Since I have excluded the classes from HOST2. Referring below FAQs in the doc https://www.eclemma.org/jacoco/trunk/doc/classids.html, What is the disadvantage of JaCoCo class ids? The fact that class ids identify a specific version of a class causes problems in setups where different classes are used at runtime and at analysis time. What happens if different classes are used at runtime and at analysis time? In this case execution data cannot be related to the analyzed classes. As a consequence such classes are reported with 0% coverage.
