Continuous Integration Builds

Official CI build server for JUnit 5. Used to perform quick checks on submitted pull requests and for build matrices including the latest released OpenJDK and early access builds of the next OpenJDK.

Code Coverage

Code coverage using JaCoCo for the latest build is available on Codecov.

A code coverage report can also be generated locally via the Gradle Wrapper by executing gradlew -PenableJaCoCo clean jacocoRootReport. The results will be available in build/reports/jacoco/jacocoRootReport/html/index.html.

Gradle Enterprise

JUnit 5 utilizes Gradle Enterprise for Build Scans, Build Cache, and Test Distribution.

The latest Build Scans are available on ge.junit.org. Currently, only core team members can publish Build Scans and use Test Distribution on that server. You can, however, publish a Build Scan to scans.gradle.com by using the --scan parameter explicitly.

The remote Build Cache is enabled by default for everyone so that local builds can reuse task outputs from previous CI builds.

Building from Source

You need JDK 17 to build JUnit 5. Gradle toolchains are used to detect and potentially download additional JDKs for compilation and test execution.

Note: If you're working on a machine with an Apple Silicon processor, you'll need to download and install a JDK 8 distribution manually (or via SDKMAN! or asdf) -- for example, one from Zulu or Liberica.

All modules can be built with the Gradle Wrapper using the following command.

gradlew clean assemble

All modules can be tested with the Gradle Wrapper using the following command.

gradlew clean test

Since Gradle has excellent incremental build support, you can usually omit executing the clean task.

Installing in Local Maven Repository

All modules can be installed with the Gradle Wrapper in a local Maven repository for consumption in other projects via the following command.

gradlew clean publishToMavenLocal
