Gradle Build Cache

Avrea provides a build cache endpoint for Gradle. Build outputs are cached so that tasks with unchanged inputs are never re-executed.

On Avrea runners

Gradle is pre-configured via ~/.gradle/init.gradle:

~/.gradle/init.gradle

gradle.settingsEvaluated { settings ->
    settings.buildCache {
        remote(HttpBuildCache) {
            url = uri("http://avrea-host:8290/gradle-build/cas/")
            push = true
            allowInsecureProtocol = true
        }
    }
}

Your workflow needs no changes to point at Avrea. Just make sure the Gradle build cache is enabled (--build-cache flag or org.gradle.caching=true in gradle.properties):

workflow.yml

jobs:
  build:
    runs-on: avrea-ubuntu-latest
    steps:
      - uses: actions/checkout@v6
      - uses: actions/setup-java@v5
        with:
          distribution: temurin
          java-version: '21'
      - run: ./gradlew build --build-cache

Manual setup

Add to your project settings.gradle:

settings.gradle

// settings.gradle
buildCache {
    remote(HttpBuildCache) {
        url = uri("http://avrea-host:8290/gradle-build/cas/")
        push = true
        allowInsecureProtocol = true
    }
}

Then enable it in your workflow:

- run: ./gradlew build --build-cache

The --build-cache flag enables the remote build cache. You can also set org.gradle.caching=true in gradle.properties to enable it by default.
