We are migrating all the project from ANT to MAVEN as part of Continuous Integration. We are using JaCoCo for new project to measure the code coverage and integrated successfully with SonarQube.

We have few existing ANT project which is using Cobertura. While migrating this to Maven I am getting the below exception

Exception

Expert, am I missing anything here?

I did not get any answer yet from anyone. But I solved this on my own as described in the

sonar importing cobertura.ser.

The issue is sonar-maven-plugin was expecting coverage.xml file but I was pointing to cobertura.ser.

I changed it to 

<sonar.cobertura.reportPath>${project.basedir}/target/site/cobertura/coverage.xml</sonar.cobertura.reportPath>

Secondly, I found one issue with cobertura-maven-plugin (version: 2.7) it is not generating coverage.xml file even though in report format I have specified xml. This issues is already pointed in the below stackoverflow link

Maven Cobertura plugin not generating coverage.xml

<plugin>
    <!-- use mvn cobertura:cobertura to generate cobertura reports -->
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>cobertura-maven-plugin</artifactId>
    <version>2.7</version>
    <configuration>
        <formats>
            <format>xml</format>
        </formats>
</plugin>

I have to pass -Dcobertura.report.format=xml this property to generate the coverage.xml

The final plugin configuration looks like this

    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>

    </plugins>

And I am using the below command to execute the code coverage and publishing to SonarQube

clean install cobertura:cobertura sonar:sonar -Dcobertura.report.format=xml
