Jenkins jacoco integration - jenkins

Question

I am trying to get the code coverage with jenkins and jacoco plugins.
I have a jacoco agent jar on the machine where my testing is being executed. I then retrieve the dump and try to get the code coverage on jenkins.
However I keep getting the below error,
[JaCoCo plugin] Collecting JaCoCo coverage data...

JaCoCo Can't add different class with same name: org/hamcrest/BaseDescription
The above link suggest to exclude the files, but if you look at the above logs, they are already being excluded but I still see this issue.

Answer 1

In my case see this:
12:35:12 [JaCoCo plugin] exclusions: [**/*koba*.class] in Jenkins logs while Jenkins Jacoco plugin performs the analysis. There's no backslashes as compared to what you get.
Secondly, the error that you are getting is due to either of the 2 reasons:
You have .java/.groovy files and after compilation, you create .class files.
It seems like there's class file (for ex: abc.java or com/test/poms/convertors/DtoToSroConverter in your case) which is present in the source folder that you have mentioned in the plugin's "source" field.
If you are creating any class files (for which you don't have a .java/.groovy file in source (src/main/java or src/main/groovy or src/test/java, src/test/groovy, src/xxx/java or src/xxx/groovy folders) then, jacoco analysis will error out with the same error i.e. it won't be able to find the respective source file (.java/.groovy) for the .class file it's analyzing.
Check, how many files are there with name starting with: DtoToSroConverter in your project.
Then, make sure the values that you mention in Jacoco plugin in Jenkins looks like this. NOTE: source code should NOT contains any test (unit/non-Unit test source) folders.
In my case, I'm saying, process all .exec files (anywhere in my project's workspace after the build/tests/jacoco process is complete) i.e. ****/*.exec**
Then, Path to class directories should always mention only the MAIN source class files (not test classes of either unit/non-unit types) i.e. I only used "build/classes/main" as these classes are generated against my source main code (src/main/java OR src/java). This value is the folder which contains your main source code classes only.
Path to source directories field should always contain the folder where the actual main source code exists (instead of including any test source code) i.e. I have used "src/java". I could have used "src/main/java" which is the Gradle/Maven standard folder structure for main source code. In my case, my main source code is in src/java folder.
Check if Path to source directories field and Path to class directories is set correctly? If yes, is there more than one file with the name: DtoToSroConverter
