# gradle/libs.versions.toml
[plugins]
lombok = "io.freefair.lombok:9.2.0"
spotless = "com.diffplug.spotless:8.1.0"
sonarqube = "org.sonarqube:7.2.2.6593"
protobuf = "com.google.protobuf:0.9.6"

// settings.gradle
plugins {
    id 'bitso.develocity' version "${develocityPluginVersion}"  // 0.2.8
    id 'org.sonarqube' version "${sonarqubePluginVersion}"      // 7.2.2.6593
}

3. Add JUnit Platform Launcher

Required for JUnit 5.11+ with Gradle 9:

subprojects {
    plugins.withType(JavaPlugin).configureEach {
        dependencies {
            testRuntimeOnly 'org.junit.platform:junit-platform-launcher'
        }
    }
}
