Features - Java 25 Maven Template

Core Feature

Java 25 Ready

This template is built specifically for Java 25, taking advantage of the latest language features and improvements.

Compiler Configuration

<maven.compiler.release>25</maven.compiler.release>

Uses the latest Java 25 compiler release setting for optimal compatibility and feature access.

CI/CD Integration

- name: "Setup JDK"
  uses: actions/setup-java@v5
  with:
    distribution: "oracle"
    java-version: 25

GitHub Actions workflow configured with Oracle JDK 25 for consistent builds and deployments.

Testing Excellence

Comprehensive testing setup with separation of concerns and modern testing libraries.

🧪

Separated Test Execution

Surefire Plugin for unit tests (*Test.java) and Failsafe Plugin for integration tests (*IT.java) with different execution phases.

⚡

Parallel Test Execution

JUnit Platform configured for parallel test execution with dynamic strategy for faster feedback loops.

🎯

Property-Based Testing

jqwik 1.9.3 for property-based testing to discover edge cases automatically with generated test data.

📐

Architecture Testing

ArchUnit 1.4.1 for testing architectural rules and ensuring code structure compliance.

🏗️

Fluent Assertions

AssertJ 3.27.6 for readable and maintainable test assertions with fluent API.

🎲

Test Data Generation

Instancio 5.5.1 for generating test data objects automatically with customizable constraints.

Parallel Test Configuration

junit.jupiter.execution.parallel.enabled = true
junit.jupiter.execution.parallel.config.strategy = dynamic
junit.jupiter.execution.parallel.mode.default = concurrent
junit.jupiter.execution.parallel.mode.classes.default = concurrent

Code Quality & Formatting

Automated code quality enforcement with industry-standard formatting and best practices.

Spotless Code Formatting

Google Java Format with AOSP style automatically applied during compilation phase.

./mvnw spotless:apply  # Format code
./mvnw spotless:check  # Verify formatting

Automated Quality Gates

Spotless formatting checks run automatically during the compile phase to ensure consistent code style.

<execution>
    <goals><goal>check</goal></goals>
    <phase>compile</phase>
</execution>

Maven Configuration & Best Practices

Optimized Maven configuration with wrapper for consistent builds across environments.

📦

Maven Wrapper

No need to install Maven locally. The wrapper ensures consistent Maven version across all environments.

⚙️

JVM Configuration

Optimized JVM settings in .mvn/jvm.config for better performance and headless operation.

🔧

Maven Optimizations

Batch mode, fail-at-end, and no transfer progress for cleaner CI/CD output.

Configuration Files

.mvn/jvm.config

-Xmx2048m -Xms512m -Djava.awt.headless=true

Optimized heap settings and headless mode for CI environments.

.mvn/maven.config

-B
--fail-at-end
--no-transfer-progress

Batch mode and optimization flags for better CI/CD experience.

Development Tools

Modern development tools and integrations for enhanced productivity.

🐚

JShell Integration

REPL development support with JShell Maven plugin for interactive Java development and experimentation.

./mvnw jshell:run

📦

Modularization Ready

Java Platform Module System (JPMS) configured with module-info.java files for both main and test sources.

🔄

jenv Configuration

Java version management with jenv for easy switching between different Java versions in development.

📦

Fat JAR Support

Maven Shade plugin available via profile for creating executable JAR files with all dependencies.

./mvnw package -Pshade

CI/CD & Automation

GitHub Actions workflow ready for continuous integration and deployment.

GitHub Actions Workflow
