Question

I am getting

Skipping JaCoCo execution due to missing execution data file:/scratch/jenkins/workspace/sonar-test/target/jacoco.exec error

My pom profile is:

                </plugin>

            </plugins>
        </build>
    </profile>

What am I missing?

Answer 1

Another reason for missing jacoco.exec can be that there aren't any unit tests in project.

Edit: I would like to know, why my answer was voted down since nobody left any reason in comments. We had the same error message in project consisting of 3 sub-projects. One of them was new and without any tests - after adding one dummy unit test error was gone.
