Sonar does not pick up test coverage information

Question

Similar to SonarQube does not display detailed report per file for fully covered classes via Gradle but not a dupe.

Sonar Qube version 3.7.4 Gradle version 2.1

Running the gradle sonarRunner generates a file test.exec which Sonar does pick up

14:50:28.167 INFO  - Analysing D:\projname\build\jacoco\test.exec
14:50:28.265 INFO  - No information about coverage per test.
14:50:28.266 INFO  - Sensor JaCoCoSensor done: 106 ms
14:50:28.529 INFO  - Execute decorators...
14:50:29.253 INFO  - Store results in database
14:50:29.391 INFO  - ANALYSIS SUCCESSFUL, you can browse http://localhost:9000/dashboard/index/com.projname

However on refreshing the said project it shows coverage at 0%

Unit Tests Coverage 0.0% 0.0% line coverage 0.0% branch coverage

I have set

sonarRunner {
    sonarProperties {
        property 'sonar.jacoco.reportPath', 'D:\\projname\\build\\jacoco\\test.exec'
        property 'sonar.junit.reportsPath','$buildDir/test-results'
        property 'sonar.tests', "$buildDir/classes/test"
     }
}

I have tried \ and forward slashes - it does not make a difference

any ideas?

EDIT

As per Peter's answer, removed the sonarProperties - so build.gradle basically is

subprojects {
   apply plugin: 'java'
   apply plugin: 'eclipse'
   apply plugin: 'sonar-runner'
   apply plugin: 'jacoco'
   sourceCompatibility  = 1.7
   group = 'com.mycomp'
   version = '1.0-SNAPSHOT'

    repositories {
        mavenCentral()
    }

    dependencies {
        testCompile 'junit:junit:4.10'
    }
}

This does not read the default exec file which is generated at D:\projname\build\jacoco\test.exec

Instead it gives the message

17:06:36.912 INFO  - Project coverage is set to 0% as no JaCoCo execution data has been dumped: D:\projname\target\jacoco.exec

Question: Does spaces in folder names cause a problem

Answer 1

Use gradle test sonarRunner to make sure that test and coverage results are up-to-date. Avoid absolute paths in build scripts. Groovy only performs String interpolation for double-quoted strings ("$buildDir/test-results"). If you have the jacoco and java plugins applied, all the Sonar properties shown in your snippet should be preconfigured correctly.
