Code Coverage not populated after sonar analysis - sonarqube

Question

I am using sonarqube5.6.1.
I have a multi module project for which i am running sonar analysis using the below command.
mvn org.sonarsource.scanner.maven:sonar-maven-plugin:3.1.1:sonar -Dsonar.host.url=http://bamboo.in.XXX.com:8085 -Dsonar.analysis.mode=publish -Dsonar.issuesReport.html.enable=true -Dsonar.dynamicAnalysis=false
But code coverage is not getting populated at all.
Can some one help. I could see the below warnings, Not sure if that's the reason.
[INFO] Process project properties
[WARNING] /!\ A multi-module project can't have source folders, so '/ssdd5/sameenud/dev/trunk/AAAA/BBBB/CCCC/DDDD/src/main/java' won't be used for the analysis. If you want to analyse files of this folder, you should create another sub-module and move them inside it.
The folder structure we have is as below,
AAAA
--BBBB
pom.xml
---CCCC
pom.xml
---DDDD
pom.xml
I tried compiling it manual, But no luck, Same problem.

I had the similar issue, 0.0% coverage & no unit tests count on Sonar dashboard with SonarQube 6.7.2:
Maven : 3.5.2,
Java : 1.8,
Jacoco : Worked with 7.0/7.9/8.0,
OS : Windows
After a lot of struggle finding for correct solution, resolved issue with this configuration my parent pom looks like:
<properties>
<!--Sonar -->
<sonar.java.coveragePlugin>jacoco</sonar.java.coveragePlugin>
<sonar.dynamicAnalysis>reuseReports</sonar.dynamicAnalysis>
<sonar.jacoco.reportPath>${project.basedir}/../target/jacoco.exec</sonar.jacoco.reportPath>
<sonar.language>java</sonar.language>
</properties>
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
</plugin>
<plugin>
<groupId>org.sonarsource.scanner.maven</groupId>
<artifactId>sonar-maven-plugin</artifactId>
<version>3.4.0.905</version>
</plugin>
<plugin>
<groupId>org.jacoco</groupId>
<artifactId>jacoco-maven-plugin</artifactId>
<version>0.7.9</version>
<configuration>
<destFile>${sonar.jacoco.reportPath}</destFile>
<append>true</append>
</configuration>
<executions>
<execution>
<id>agent</id>
<goals>
<goal>prepare-agent</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</pluginManagement>
</build>
I've tried few other options like jacoco-aggregate & even creating a sub-module by including that in parent pom but nothing really worked & this is simple. I see in logs <sonar.jacoco.reportPath> is deprecated,but still works as is and seems like auto replaced on execution or can be manually updated to <sonar.jacoco.reportPaths> or latest. Once after doing setup, in cmd start with mvn clean install then mvn org.jacoco:jacoco-maven-plugin:prepare-agent install & then do mvn sonar:sonar , this is what I've tried please let me know if some other best possible solution available.Hope this helps!! If not please post your question..

Answer 2

SonarQube (and more specifically SonarJava analyzer) is not computing the coverage. You have to provide a coverage report in order for the analysis to import its results in the SonarQube UI and display coverage.
See the documentation for more information on how to achieve this.
