问题
I'm using JaCoCo for Code Coverage. The Unit Test reports are created with junit and they are imported correctly, so that the unit test information is shown properly. The problem is, that I get the error message: No information about coverage per test. and the code coverage is shows the value 0% for unit tests, integration tests and overall coverage. I checked all required information in the sonar-project.properties like binary, src, tests etc.
I'm using:
- SonarQube 4.5.1
- SonarRunner 2.4
- MySQL
- junit 4.1.1
- jacoco 0.7.2
The jacoco.exec is located in a file /target in the project base directory.
Following you can see the sonar-project.properties: From my point of view all necessary paths are set properly. (i.e. binary, src, tests)
Comma-separated paths to directories with sources (required)
sonar.sources=src
compiled code
sonar.java.binaries=class
source code of unit tests
sonar.tests=test/src
Comma-separated paths to files with third-party libraries (JAR files in the case of Java)
sonar.java.libraries=jar
Language
sonar.language=java
Encoding of the source files
sonar.sourceEncoding=UTF-8
Additional parameters
sonar.my.property=value
Set Project Base
sonar.projectBaseDir=C:/snapshots/steffen_latest/software/java
Tells SonarQube to reuse existing reports for unit tests execution and coverage reports
sonar.dynamicAnalysis=reuseReports
JUnit path
sonar.surefire.reportsPath=test/report/junit
Tells SonarQube where the unit tests execution reports are
sonar.junit.reportsPath=test/report/junit
Tells SonarQube that the code coverage tool by unit tests is JaCoCo
sonar.java.coveragePlugin=jacoco
Import JaCoCo code coverage report.
Tells SonarQube where the unit tests code coverage report is
Unit Tests Coverage
sonar.jacoco.reportPath=target/jacoco.exec
Tells SonarQube where the integration tests code coverage report is
sonar.jacoco.itReportPath=target/it-jacoco.exec
This is the logging file from sonar-runner:

Could anyone give me an advice what could be the problem? Since I don't know what is the problem... I'm working on this issues since a few days and I really don't know what to do..
Thank you in advance.
回答1:
Have you tried using the prepare-agent?
mvn clean org.jacoco:jacoco-maven-plugin:prepare-agent install
Also, if your coverage keeps showing 0%, you might need to follow this advice:
If your project already uses the argLine to configure the surefire-maven-plugin, be sure that argLine defined as a property, rather than as part of the plugin configuration."
回答2:
With this Maven configuration I am able to see coverage per test data.
You need to configure sonar-jacoco-listeners to get coverage per test.
Please be aware that it is deprecated by sonar: "this feature is deprecated at SonarQube level and will no longer receive further improvements/maintenance."

In my case below commands works.
mvn clean org.jacoco:jacoco-maven-plugin:0.7.3.201502191951:prepare-agent install
mvn sonar:sonar
To check code coverage: Start SonarQube server -> Run above two commands one after another & you will see code coverage in SonarQube Client.
FYI: My SonarQube Version - 5.1.2. You can download latest version from SonarQube Download
回答4:
I use JUnit as well and in my case the issue was because of having TestNG dependency in my pom.xml. After removing this unnecessary dependency, everything started to work as expected.
回答5:
Make sure to split up build and analysis to two different build steps:
mvn clean install
mvn sonar:sonar
