Test coverage is always null in SonarQube after jenkins build job - maven

Question

I am using the latest SonarQube 6.4, Jenkins 2.60.1 and I have one application with some tests. After running the application in eclipse using the coverage plugin I can see approximately 90% in test coverage. My problem starts when I use Jenkins to build my application and then SonarQube displays the result but the test coverage is always null. I believe that I am missing something so any help will be appreciated.
Here is my pom.xml file:

Here are my Jenkins properties in the Post Steps(using Execute SonarQube Scanner):
sonar.jdbc.dialect=mssql
sonar.projectKey=BillApplication
sonar.projectName=BillApplication
sonar.projectVersion=1.0
sonar.projectBaseDir=.
sonar.sources=.
sonar.binaries=target/classes
sonar.dynamicAnalysis=reuseReports
sonar.junit.reportsPath=build/test-reports/jacoco.exec
sonar.java.coveragePlugin=jacoco
sonar.core.codeCoveragePlugin=jacoco
sonar.junit.reportsPath=target/surefire-reports
sonar.jacoco.reportPath=target/coverage-reports/jacoco-ut.exec
And final the command that I use is this:
clean org.jacoco:jacoco-maven-plugin:prepare-agent install -P
integration-tests --fail-at-end
If you need anything else of my configuration I will post it in this place.

Answer 1

The post build action is deprecated.
Yours is a Maven project, so there's no need to provide properties explicitly.
As described in the docs, after your build command all you really need to do is this: $SONAR_MAVEN_GOAL -Dsonar.host.url=$SONAR_HOST_URL
