Jenkins jacoco plugin empty report - maven

Question

I have a project where I use Jacoco to calculate the code coverage.
I use maven configuration like here :
http://www.petrikainulainen.net/programming/maven/creating-code-coverage-reports-for-unit-and-integration-tests-with-the-jacoco-maven-plugin/
With Jenkins, I run "mvn clean install test". It generates the report in the /target/site/jacoco-ut/ folder. If I open the index.html file, I see this :
But when I open JaCoCo Coverage Report in jenkins job, I see this :
It says that every test cover 0% of the code. I don't understand why I don't have the same result that I have in the html report.

And my jenkins configuration :
What is my error ?

Answer 1

I found a jenkins issue similar to my problem :
https://issues.jenkins-ci.org/browse/JENKINS-28652
The error is caused by jacoco version.
The version 0.7.5.201505241946 is bugged.
I switch for the version 0.7.4.201502262128 and now it works.

Answer 2

I had similar issue and it is fixed by just updating the "jacoco-maven-plugin" version to 0.7.7.201606060606 and "maven-surefire-plugin" version to 2.19.1
I hope this will work for you.

Answer 3

Try to use in Jenkins Plugin :
Path to exec files = /.exec
And I use this pom :
<jacoco.it.execution.data.file>${project.build.directory}/coverage-reports/jacoco-it.exec</jacoco.it.execution.data.file>
<jacoco.ut.execution.data.file>${project.build.directory}/coverage-reports/jacoco-ut.exec</jacoco.ut.execution.data.file>
<plugin>
<groupId>org.jacoco</groupId>

<executions>
<execution>
<id>pre-integration-test</id>
<phase>pre-integration-test</phase>
<goals>
<goal>prepare-agent-integration</goal>
</goals>
<configuration>
<destFile>${jacoco.it.execution.data.file}</destFile>

</execution>
<!-- Ensures that the code coverage report for integration tests after -->
