For specific guidelines regarding contributions, please see [CONTRIBUTING.md] in the root directory of the project. Those willing to use milestone or SNAPSHOT releases are encouraged to file feature requests and bug reports using the project's [issue tracker](https://github.com/junit-team/junit5/issues). Issues marked with an <a href="https://github.com/junit-team/junit5/issues?q=is%3Aissue+is%3Aopen+label%3Aup-for-grabs">`up-for-grabs`</a> label are specifically targeted for community contributions. ## Getting Help Ask JUnit-related questions on [StackOverflow] or use the Q&A category on [GitHub Discussions]. ## Continuous Integration Builds [](https://github.com/junit-team/junit5/actions/workflows/main.yml) [](https://github.com/junit-team/junit5/actions/workflows/cross-version.yml) Official CI build server 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 clean jacocoRootReport`. The results will be available in `build/reports/jacoco/jacocoRootReport/html/index.html`. ## Develocity [](https://ge.junit.org/scans) JUnit utilizes [Develocity](https://gradle.com/) for [Build Scans](https://scans.gradle.com/), [Build Cache](https://docs.gradle.org/current/userguide/build_cache.html), and [Predictive Test Selection](https://docs.gradle.com/enterprise/predictive-test-selection/). The latest Build Scans are available on [ge.junit.org](https://ge.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](https://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 24] 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` ## Dependency Metadata [](https://central.sonatype.com/search?namespace=org.junit.jupiter) [](https://central.sonatype.com/search?namespace=org.junit.vintage) [](https://central.sonatype.com/search?namespace=org.junit.platform) Consult the [Dependency Metadata] section of the [User Guide] for a list of all artifacts of the JUnit Platform, JUnit Jupiter, and JUnit Vintage.
