Agent-skills-standard java-tooling

Configure Maven, Gradle, and static analysis for Java projects. Use when setting up Java build tooling, configuring Spotless or Checkstyle, managing JDK versions with sdkman, writing Dockerfiles for Java services, or adding SpotBugs/SonarLint. (triggers: pom.xml, build.gradle, build.gradle.kts, mvnw, gradlew, .sdkmanrc, spotbugs, checkstyle, spotless, eclipse-temurin)

Java Tooling Standards

Priority: P2 (RECOMMENDED)

Implementation Guidelines

  • JDK Setup: Use 
    .sdkmanrc
     or 
    .java-version
     to lock project to LTS Support (17 or 21). Configure Gradle toolchain via 
    java { toolchain { languageVersion = JavaLanguageVersion.of(21) } }
    for reproducible builds.
  • Maven & Wrapper: Use 
    pom.xml
     with 
    <dependencyManagement>
    . ALWAYS use 
    mvnw
     wrapper.
  • Gradle & Catalog: Prefer 
    build.gradle.kts
     (Kotlin DSL) with 
    libs.versions.toml
     (Version Catalog). Use 
    gradlew
     wrapper.
  • Formatting: Enforce Google Style Guide using 
    Spotless
     (
    googleJavaFormat()
    plugin) or 
    Checkstyle
    .
  • Static Analysis: Integrate 
    SpotBugs
     or 
    SonarLint
     for deep analysis. Use 
    Detekt
     if using Kotlin.
  • Docker: Use Multi-stage Dockerfiles. Use 
    eclipse-temurin
     as base image.
  • CI/CD: Configure GitHub Actions or GitLab CI to run 
    mvnw test
    or 
    gradlew build
    on every PR.

Anti-Patterns

  • No Global Installs: Always use mvnw/gradlew wrappers; never rely on system Maven/Gradle.
  • No Fat Jars: Prefer layered Docker images over uber-jars for better layer caching.
  • No Snapshots in Prod: Never use -SNAPSHOT dependency versions in production builds.
