Official CI build that performs quick checks on submitted pull requests and runs build matrices for the latest release and early access versions of OpenJDK.
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 clean jacocoRootReport. The results will be available
in build/reports/jacoco/jacocoRootReport/html/index.html.
JUnit utilizes Develocity for Build Scans, Build Cache, and Predictive Test Selection.
The latest Build Scans are available on develocity.junit.org. Currently,
only core team members can publish Build Scans 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.
You need JDK 25 to build JUnit. Gradle toolchains are used to detect and potentially download additional JDKs for compilation and test execution.
All modules can be built and tested with the Gradle Wrapper using the following command:
./gradlew build
All modules can be installed in a local Maven repository for consumption in other local projects via the following command:
./gradlew publishToMavenLocal
