lombok = "io.freefair.lombok:9.1.0"
spotless = "com.diffplug.spotless:8.1.0"
sonarqube = "org.sonarqube:7.2.2.6593"
// 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
