How to Integrate SonarQube into a Multi‑Module Spring Boot Project with Gradle 3.3

In a Spring Boot multi‑module project that uses Gradle 3.3, you can enable SonarQube 5.6.6 analysis by adding the SonarQube plugin and its repository to the root build.gradle file.

Repository and Plugin Dependency

buildscript {
    repositories {
        maven { url "https://plugins.gradle.org/m2/" }
    }
    dependencies {
        classpath "org.sonarsource.scanner.gradle:sonarqube-gradle-plugin:2.3"
    }
}

Because the project is multi‑module, place this configuration in the outermost build.gradle.

Apply SonarQube Plugin to All Subprojects

subprojects {
    sonarqube {
        properties {
            property "sonar.host.url", "http://localhost:9000/"
            property "sonar.jdbc.url", "jdbc:mysql://my.server.com/sonar"
            property "sonar.jdbc.driverClassName", "com.mysql.jdbc.Driver"
            property "sonar.jdbc.username", "sonar"
            property "sonar.jdbc.password", "sonar"
        }
    }
    apply plugin: 'org.sonarqube'
}

Full Example of build.gradle

buildscript {
    repositories { maven { url "https://plugins.gradle.org/m2/" } }
    dependencies { classpath "org.sonarsource.scanner.gradle:sonarqube-gradle-plugin:2.3" }
}
apply plugin: 'org.sonarqube'
apply plugin: 'idea'

group = 'com.bootcwenao'
version = '0.1.0-SNAPSHOT'

subprojects {
    apply plugin: 'java'
    sourceCompatibility = 1.8
    targetCompatibility = 1.8
    sourceSets {
        main { java.srcDir 'src/main/java'; resources.srcDir 'src/main/resources' }
        test { java.srcDir 'src/test/java'; resources.srcDir 'src/test/resources' }
    }
    sonarqube {
        properties {
            property "sonar.host.url", "http://localhost:9000/"
            property "sonar.jdbc.url", "jdbc:mysql://my.server.com/sonar"
            property "sonar.jdbc.driverClassName", "com.mysql.jdbc.Driver"
            property "sonar.jdbc.username", "sonar"
            property "sonar.jdbc.password", "sonar"
        }
    }
}

task wrapper(type: Wrapper) {
    gradleVersion = '3.3'
}

Running SonarQube

Start the SonarQube server (e.g., StartSonar.bat) and then execute the analysis with: gradle sonarqube -x test This command runs SonarQube analysis on all modules while skipping tests.
