I am running a Gradle build inside the IntelliJ Java IDE. The SonarQube runner Gradle plugin is used along with the JaCoCo Gradle plugin.

Problem: I am getting the message No information about coverage per test., (not a duplicate of this post, see below) and the coverage appears in SonarQube, but only as an overall percentage, not a detailed report per file:

Am I doing something wrong? Is it a bug in SonarQube maybe (as it was with Cobertura recently)?

Here is my build.gradle:

repositories {
    mavenCentral()
}

apply plugin: 'java'
apply plugin: 'jacoco'
apply plugin: 'sonar-runner'

sourceCompatibility = 1.7
project.version = '1.0'
project.group = 'com.acme.sandbox'
project.description = 'just a test project'

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.11'
}

// JaCoCo test coverage configuration
tasks.withType(Test) { task ->
    jacoco {
        append = false
    }
}

// Sonar configuration
sonarRunner {
  sonarProperties {
    property 'sonar.host.url', 'http://host:port'
    property 'sonar.jdbc.url', 'myJdbcURL'
    property 'sonar.jdbc.username', 'dbuser'
    property 'sonar.jdbc.password', 'dbpass'
    property 'sonar.login', 'builduser'
    property 'sonar.password', 'buildpass'

    property 'sonar.profile', 'profilename'
    property 'sonar.branch', 'DEV'
    property 'sonar.language', 'java'
    property 'sonar.sourceEncoding', 'UTF-8'
    property 'sonar.verbose', 'true'
    //property 'sonar.tests', "$projectDir\\src\\test\\java"
    //property 'sonar.binaries', "${buildDir}\\classes\\main,${buildDir}\\classes\\test"

    //property 'sonar.java.coveragePlugin', 'jacoco'
    property 'sonar.jacoco.reportPath', "${buildDir}\\jacoco\\test.exec"
    property 'sonar.junit.reportsPath', "${buildDir}\\test-results"
  }
}

Now if you execute a clean, followed by sonarRunner, a JaCoCo test.exec file gets created and processed:

This post suggests to set sonar.tests, which I've tried to no effect. The log file shows that test sources and binaries are detected to be at the correct locations.

FWIW, I used the same settings with a Maven build and it worked. Can't use Maven here though.

Version numbers:

SonarQube 4.3
SonarQube Java Ecosystem 2.2.1
Gradle 1.12 (also: 1.11)
IntelliJ IDEA Ultimate 13.1.3
Java 1.7

Here is the full test project for download, and also the full log.

This is what is called 'wanted' behaviour. Sonar does not display classes with 100% coverage. In your project you have one class fully covered by tests, so nothing to show.

FYI:

Even if you have 100% covered class, you can look at this class coverage by searching in sonars search box (top-right corner).

If you see .exec and it is of valuable size, then you already collected coverage data.

See my FAQ

I got this code analysis widget for your project:

And finally after I added another method uncovered by tests and test coverage dropped to 80%:

I got what you need - coverage by line:

By the way, your modified build.gradle for my sonar (this // does not work for me):

repositories {
    mavenCentral()
}

apply plugin: 'java'
apply plugin: 'jacoco'
apply plugin: 'sonar-runner'


sourceCompatibility = 1.7
project.version = '1.0'
project.group = 'com.acme.sandbox'
project.description = 'just a test project'

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.11'
}

// JaCoCo test coverage configuration
tasks.withType(Test) { task ->
    jacoco {
        append = false
    }
}

// Sonar configuration
sonarRunner {
    sonarProperties {
        // general information about the SonarQube server
        property 'sonar.host.url', 'http://localhost:9000'
        property 'sonar.jdbc.url', 'jdbc:h2:tcp://localhost:9092/sonar'
        property 'sonar.jdbc.validationQuery', 'select 1'
        property 'sonar.jdbc.driverClassName', 'org.hibernate.dialect.H2Dialect'
        property 'sonar.jdbc.password', 'sonar'
        property 'sonar.jdbc.password', 'sonar'
        property 'sonar.login', 'jenkins'
        property 'sonar.password', 'jenkins'

        // information about this project
        //property 'sonar.profile', 'profilename'
        property 'sonar.branch', 'DEV'
        property 'sonar.language', 'java'
        property 'sonar.sourceEncoding', 'UTF-8'
        property 'sonar.verbose', 'true'
        //property 'sonar.tests', "$projectDir\\src\\test\\java"
        property 'sonar.binaries', "${buildDir}/classes/main/"

        // execute JaCoCo before the SonarQube run to have report file ready
        //property 'sonar.java.coveragePlugin', 'jacoco'
        property 'sonar.jacoco.reportPath', "${buildDir}/jacoco/test.exec"
        property 'sonar.junit.reportsPath', "${buildDir}/test-results"
    }
}
