JaCoCo coverage is missing

maven sonarqube jacoco maven-surefire-plugin jacoco-maven-plugin

I've been working on this for hours, and every solution I've tried that I've found online makes no difference.

I have a project which is written in Kotlin. I have the Kotlin plugin installed on my sonar server. I am using JaCoCo plugin to generate code coverage report for sonar.

My project is multi-module, but only 1 sub-module has unit tests, and so I have defined my JaCoCo plugin there.

I am also using the Surefire plugin.

Here are my properties in my pom.xml

<properties>
    <sonar.java.binaries>target/classes</sonar.java.binaries>
    <sonar.core.codeCoveragePlugin>jacoco</sonar.core.codeCoveragePlugin>
    <sonar.jacoco.reportPath>target/jacoco.exec</sonar.jacoco.reportPath>
    <sonar.language>kotlin</sonar.language>
    <sonar.sources>src/main</sonar.sources>
    <sonar.tests>src/test</sonar.tests>
    <sonar.verbose>true</sonar.verbose>
    <sonar.jacoco.reportsPath>target</sonar.jacoco.reportsPath>
    <sonar.junit.reportsPath>target/surefire-reports</sonar.junit.reportsPath>
    <sonar.surefire.reportsPath>target/surefire-reports</sonar.surefire.reportsPath>

    <surefireArgLine/>
</properties>

Here is my surefire plugin:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
        <excludes>
            <exclude>**/*IT.java</exclude>
        </excludes>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.junit.platform</groupId>
            <artifactId>junit-platform-surefire-provider</artifactId>
            <version>1.2.0</version>
        </dependency>
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-engine</artifactId>
            <version>${junit-jupiter.version}</version>
        </dependency>
    </dependencies>
</plugin>

And here is my JaCoCo plugin:

<plugin>
    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.8.1</version>
    <configuration>
        <append>true</append>
    </configuration>
    <executions>
        <execution>
            <id>pre-unit-test</id>
            <goals>
                <goal>prepare-agent</goal>
            </goals>
            <configuration>
                <destFile>target/jacoco.exec</destFile>
                <propertyName>surefireArgLine</propertyName>
            </configuration>
        </execution>
        <execution>
            <id>post-unit-test</id>
            <phase>test</phase>
            <goals>
                <goal>report</goal>
            </goals>
        </execution>
    </executions>
</plugin>

After running my unit tests, I generate my sonar report like so:

mvn sonar:sonar -Dsonar.projectName=vqs -Dsonar.projectKey=vqs

And Sonar reports no coverage.sonar report summary

At one point in time, I was getting code coverage data. At this time, the project was a single module, and was potentially not using surefire (I can't remember for sure).

Hoping somebody will see my error and help me out!

Thanks, Tonya

With help from @Godin in his comments above (thank you very much) I have code coverage working.

This may not be the only solution, but it is one that works for me.

First, I removed the official sonar-kotlin-plugin from my extensions/plugins directory, and added instead this one: https://github.com/arturbosch/sonar-kotlin

Second, I updated my properties, which seemed to be out of date, to resemble what is outlined in this sample: https://github.com/akquinet/kotlin-calculator/blob/master/pom.xml

Properties (excerpt)

<properties>
    <!-- Sonar configuration -->
    <jacoco.report.ut>${project.build.directory}/jacoco-ut.exec</jacoco.report.ut>
    <jacoco.report.it>${project.build.directory}/jacoco-it.exec</jacoco.report.it>

    <sonar.language>kotlin</sonar.language>
    <sonar.sources>src/main/java</sonar.sources>
    <sonar.tests>src/test/java</sonar.tests>
    <sonar.junit.reportPaths>${project.build.directory}/surefire-reports</sonar.junit.reportPaths>
    <sonar.jacoco.reportPaths>${jacoco.report.ut},${jacoco.report.it}</sonar.jacoco.reportPaths>
</properties>
