Groovy Question

How to report Jacoco Groovy code coverage to Sonar using new Gradle SonarQube plugin?

I've a multi-module Groovy project using Gradle. I applied jacoco, sonarqube plugins.

I was able to

  1. Find build/jacoco/test.exec. Jenkins was able to render it right.

  2. Browse jacocoHtml with all code coverage details

  3. Find Unit tests results and Source code on SonarQube

Code Coverage
wasn't getting reported to SonarQube.

Here's my build.gradle

plugins {
id "org.sonarqube" version "2.0.1"

allprojects {
group = 'my'
version = '1.0-SNAPSHOT'

subprojects {
apply plugin: 'groovy'
apply plugin: "jacoco"

dependencies {
compile group: 'org.codehaus.groovy', name: 'groovy-all', version: '2.4.1'
testCompile group: 'org.spockframework', name: 'spock-core', version: '1.0-groovy-2.4'
testCompile group: 'org.assertj', name: 'assertj-core', version: '2.4.1'

I observed following log statements during a build.

No binary directories defined for project core.
Project coverage is set to 0% since there is no directories with classes.

I then tried adding following to subprojects or allprojects and still the coverage wasn't being reported to SonarQube.

sonarqube {
properties {
property "sonar.groovy.jacoco.reportPath", "${project.buildDir}/jacoco/test.exec"
property "sonar.jacoco.reportPath", "${project.buildDir}/jacoco/test.exec"
property "sonar.binaries", "${project.buildDir}/classes"
property "sonar.groovy.binaries", "${project.buildDir}/classes"

How can I enable reporting Jacoco Groovy code coverage to SonarQube?

Answer Source

You may have seen my comments as I battled with the same problem.

I've found the groovy plugin's site, where an issue is reported as follows:

sonar.groovy.binaries is resolved only once for the root project. In a multi-module project where the property is not defined on the root module but only on leaf modules this cause missing coverage information.

So even if it's set for your module:

":myspecialsubmodule.sonar.groovy.binaries" -> "/home/user/Projects/root-project/myspecialsubmodule/build/classes/main"

It won't work, until it's set for the root.

After setting the config specifically on the root (for now, until the issue is fixed) made it work for me.

property "sonar.groovy.binaries", "$"

I will keep track of the github issue to know when I can remove this workaround.
