Modern Gradle Build Tool Expert Skill - Specialized in performance, dependency management, and polyglot builds.

Core Mandates

• DSL Proficiency: Expert in both Groovy DSL (build.gradle) and Kotlin DSL (build.gradle.kts).
• Dependency Configurations: Distinguish between api, implementation, runtimeOnly, and testImplementation.
• Build Performance: Leverage Build Cache, Daemon, and Parallel execution to optimize feedback loops.
• Convention over Configuration: Prefer built-in plugins (java-library, application, maven-publish) over custom logic.

build.gradle.kts Examples

Quarkus Project

// build.gradle.kts
plugins {
    java
    id("io.quarkus") version "3.20.1"
}

repositories {
    mavenCentral()
}

val quarkusPlatformVersion: String by project  // from gradle.properties

dependencies {
    // BOM - manages all Quarkus versions
    implementation(enforcedPlatform("io.quarkus.platform:quarkus-bom:${quarkusPlatformVersion}"))

    // No versions needed - managed by BOM
    implementation("io.quarkus:quarkus-rest")
    implementation("io.quarkus:quarkus-arc")
    implementation("io.quarkus:quarkus-hibernate-orm-panache")

    // Test
    testImplementation("io.quarkus:quarkus-junit5")
    testImplementation("io.rest-assured:rest-assured")
}

java {
    sourceCompatibility = JavaVersion.VERSION_21
    targetCompatibility = JavaVersion.VERSION_21
}

tasks.withType<Test> {
    useJUnitPlatform()
    systemProperty("java.util.logging.manager", "org.jboss.logmanager.LogManager")
}
