How to get SonarQube code coverage for scala project

Question

I am running the goal from Teamcity for Scala project as org.jacoco:jacoco-maven-plugin:prepare-agent -U sonar:sonar My pom.xml file looks like:

<sonar-maven-plugin.version>2.0</sonar-maven-plugin.version>
<!-- Sonar -->
        <jacoco.version>0.7.9</jacoco.version>
        <sonar.projectName>ds-rfds</sonar.projectName>
        <sonar.projectDescription>ds-rfds</sonar.projectDescription>
        <sonar.core.codeCoveragePlugin>jacoco</sonar.core.codeCoveragePlugin>
        <sonar.scala.coverage.reportPaths>${project.basedir}/ds-rfds/target</sonar.scala.coverage.reportPaths>
        <sonar.dynamicAnalysis>reuseReports</sonar.dynamicAnalysis>
        <sonar.language>scala</sonar.language>
        <junit.version>4.11</junit.version>

I cannot get report and it giving error as:

Sensor Scoverage sensor for Scala coverage [sonarscala]
18:34:58
    [INFO] Importing coverage from /mrit_cm3/apps/teamcity/7.1.3/buildagent1/work/84f58bcce55c6907/ds-rfds/target

How should I fix this? I am using SonarQube Enterprise EditionVersion 7.9.1

You need to [jacoco:report](https://stackoverflow.com/questions/68157168/multiple-maven-modules-sonar-code-coverage-is-showing-zero-on-sonar-qube/68160007#68160007) or jacoco-report-aggregate — Ian W, Sep 30 '21 at 07:48

SonarQube does not create code coverage report, it just reads it. I suspect that you missing command that will be crate report. It should look like this:

    <groupId>org.jacoco</groupId>
    <artifactId>jacoco-maven-plugin</artifactId>
    <version>0.8.7</version>
    <executions>
     <execution>
         <id>prepare-agent</id>
         <goals>
             <goal>prepare-agent</goal>
         </goals>
     </execution>
     <execution>
         <id>report</id>
         <phase>prepare-package</phase>
         <goals>
             <goal>report</goal>
         </goals>
     </execution>
     <execution>
         <id>post-unit-test</id>
         <phase>test</phase>
         <goals>
             <goal>report</goal>
         </goals>
         <configuration>
             <!-- Sets the path to the file which contains the execution data. -->
             <dataFile>target/jacoco.exec</dataFile>
             <!-- Sets the output directory for the code coverage report. -->
             <outputDirectory>target/jacoco-ut</outputDirectory>
         </configuration>
     </execution>
 </executions>
 <configuration>
     <systemPropertyVariables>
         <jacoco-agent.destfile>target/jacoco.exec</jacoco-agent.destfile>
     </systemPropertyVariables>
 </configuration>

It is important to noticed this <execution><id>post-unit-test</id> part, since here is where file is created.

Also, you will need to set this path in sonarqube properties (path :<SONAR_QUBE_INSTALL_FOLDER>\conf\sonar.properties) and add the following:

sonar.junit.reportsPath=target/surefire-reports
sonar.surefire.reportsPath=target/surefire-reports
sonar.jacoco.reportPath=target/coverage-reports/jacoco-unit.exec
sonar.binaries=target/classes
sonar.java.coveragePlugin=jacoco
sonar.verbose=true
