How to get SonarQube code coverage for scala project - scala

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

java.io.FileNotFoundException: /mrit_cm3/apps/teamcity/7.1.3/buildagent1/work/84f58bcce55c6907/ds-rfds/target (No such file or directory)
How should I fix this?
I am using SonarQube Enterprise EditionVersion 7.9.1

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
