java-bootstrap

I put together this repo to serve as a starting point for what I want in a personal Java project:

• Java 21
• Gradle 9.4.1
• JUnit 6 and AssertJ
• Spotless for formatting
• Error Prone for static analysis
• JaCoCo test coverage
• CI checks

Quick Start

Compile the app:

./gradlew classes

Run the sample program:

java -cp build/classes/java/main me.graceteng.HelloWorld

Expected output:

Hello World!

Run the test suite:

./gradlew test

Common Commands

Build the project:

./gradlew build

Run formatting checks:

./gradlew spotlessCheck

Generate a JaCoCo coverage report:

./gradlew jacocoTestReport

Test coverage reports go in build/reports/jacoco/test/.

CI

GitHub Actions runs the following checks on pushes and pull requests to main:

• wrapper validation
• Java 21 setup
• spotlessCheck
• build
• jacocoTestReport
