Welcome to the Linux Foundation Forum!

Lab 9: Continous Testing - Code Coverage with Jacoco not working!

I am running a selfhosted Dockerized Gitlab, Jenkins, Docker-Repository.
In this lab the results of the test coverage and the report generated by Jacoco should be shown with the help of the Jacoco Plugin on my Pipepline in Jenkins.
Unfortunately the result ist always 0% since the Jacoco-Test-Suite is skipping an important step.

I have tried updating the Java-Version of the project also the needed plugins in the maven pom file.

The main message:

[INFO] --- jacoco-maven-plugin:0.8.6:report (post-unit-test) @ code-coverage-jacoco ---
[INFO] Skipping JaCoCo execution due to missing execution data file.

Here is the whole console log hope somebody can shed some light into the issue.

    To me this seems to be some issue with the tooling involved. I would check this by trying to recreate the issue and report my findings.
