GitHub Actions Workflow for Cache Gradle Builds

Cache Gradle so CI builds reuse dependencies and outputs.

This workflow uses the official Gradle setup action, which manages the dependency and build cache for you.

The workflow

name: CI
on: [push, pull_request]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-java@v4
        with: { distribution: temurin, java-version: '21' }
      - uses: gradle/actions/setup-gradle@v4
      - run: ./gradlew build

Notes

• gradle/actions/setup-gradle handles caching automatically.
• Cache is only written from the default branch to avoid PR pollution.
• Use the wrapper (./gradlew) for reproducible Gradle versions.
