Question

How do I configure my Gradle build to fail when there are Sonar violations?

I want my Gradle build to fail if there are any are any critical or blocker violations in Sonar, is this functionality supported? If so, is it documented anywhere?

Answer 1

1) You must install the Build Breaker Plugin on the server side into /path/to/sonarqube/extensions/plugins/ see full instruction here

https://github.com/SonarQubeCommunity/sonar-build-breaker

2) you must use the SonarQube Scanner for Gradle

3) In your gradle config sonar.buildbreaker.skip properties must be false

buildscript {
    repositories {
    ...
        maven {
            // for sonarqube
            url "https://plugins.gradle.org/m2/"
        }   
    }

    dependencies {
        classpath 'org.sonarsource.scanner.gradle:sonarqube-gradle-plugin:1.2'
    }
}

apply plugin: "org.sonarqube"

sonarqube {
        properties {
        property "sonar.projectKey", "your.project"  
        property "sonar.buildbreaker.skip" , "false"
        }
}

4) You will probably want to add a Quality Gate in sonarQube (server side). For more information check this

It's not something that can be configured on the build side. Instead, the "build breaker plugin" has to be configured on the Sonar side. I'm not completely sure if it works with Gradle, but I think it does.
