Hi community,

I am having trouble with Sonar reading the coverage information from test result. The version of Sonar I am using is 7.9.2, and the parts of my pom files that refer to sonarqube and jacoco are:

```
<properties>

                </execution>
            </executions>
        </plugin>
    </plugins>
 </build>

```

After I do:

> mvn clean package sonar:sonar -‘Dsonar.host.url’=“[http://dummy.sonar:8080/](http://dummy.sonar:8080/)”

The jacoco files are generated properly: jacoco.xml and jacoco.exec:

But when I check the result in Sonar, the coverage is 0:

Hi Roko,

Welcome to the community!

A couple things strike me here. First, there’s nothing in your log about reading the JaCoCo report. Also, I notice you specify the path to it via a pom property, but that should be picked up automatically (as should projectKey and projectName, for that matter).

I suggest two steps, taken separately. First, on your analysis command line add `-Dsonar.scanner.dumpToFile=[path to file]` (you’ll find the description [here](https://docs.sonarqube.org/7.9/analysis/analysis-parameters/)) to see what property key/value pairs analysis is getting. Second, try commenting out some (most? all?) of those properties & see what happens.

Hi Ann,

Thank you for the reply. I tried both things:

- When I use `Dsonar.scanner.dumpToFile=[path to file]` , the only jacoco property I see in the dumped file is jacocoArgLine, does this mean that I am missing some sonar-jacoco configuarion?

- When I comment out most of/all of the properties, I can’t see any data on my sonar host url.

Regards,  
Roko

Hi Roki,

Possibly. Looking at your properties…

```auto
    <sonar.projectKey>test-service</sonar.projectKey>

```

This should be picked up from your pom. No need to include this here

```auto
    <sonar.projectName>test-service</sonar.projectName>

```

ditto

```auto
    <sonar.java.coveragePlugin>jacoco</sonar.java.coveragePlugin>

```

I have super-vague memories that this used to be a thing, but it isn’t any more. You can just drop this.

```auto
    <project.test.result.directory>${project.build.directory}/test-results</project.test.result.directory>

```

Should also be picked up automatically

```auto
    <sonar.java.codeCoveragePlugin>jacoco</sonar.java.codeCoveragePlugin>

```

See `sonar.java.coveragePlugin` above.

```auto

```

I would have expected this to be picked up automatically. I don’t actually see test report generation in your command. Are you sure the reports are generated _before_ analysis?

```auto
    <sonar.language>java</sonar.language>
</properties>

```

This property had been deprecated for years when it was finally decommissioned about a year(?) ago. It’s not doing anything but taking up space. You should just go ahead & delete it.

Wanna share your analysis logs?
