Jacoco code coverage show 0% coverage on Jenkins
I have read most of the answers available for similar questions but none of those fit to answer my question.
My profile in pom file looks like this:
<plugins>

When I run my jenkins job with maven goal clean install -P test-coverage
I See this in my Jenkins log:

This is how my Jenkins configuration for Jacoco looks like:
Answer
In my case I was using jacocoant 0.6 and the jaCoCo plugin for jenkins was 2.2.0. From the jaCoCo plugin github page:
Version 2.0.0 and higher requires using JaCoCo 0.7.5 or newer, if your projects still use JaCoCo 0.7.4, the plugin will not display any code-coverage numbers any more! In this case please use version 1.0.19 until you can update jacoco in your codebase. https://github.com/jenkinsci/jacoco-plugin
