Binary builds that track the latest changes on the master branch are available on [Dockerhub](https://hub.docker.com/r/consensys/teku) using the `develop` version or as binary downloads ([tar.gz format](https://artifacts.consensys.net/public/teku/raw/names/teku.tar.gz/versions/develop/teku-develop.tar.gz) or [zip format](https://artifacts.consensys.net/public/teku/raw/names/teku.zip/versions/develop/teku-develop.zip)). We recommend only using release versions for Mainnet, but `develop` builds are useful for testing the latest changes on testnets. Release notifications are available via: * Sign up to our [release announcements](https://pages.consensys.net/teku-sign-up) email list (release and important announcements only, no marketing) * Follow us on [Twitter](https://twitter.com/Teku_Consensys) * `teku` in [Consensys Discord](https://discord.gg/7hPv2T6), * Subscribe to release notifications on github for [teku](https://github.com/Consensys/teku) ## Build Instructions ### Install Prerequisites * Java 21+ Note: Official builds of Teku are performed with Java 21. Building on a more recent version of Java is supported, but the resulting build will not work on earlier versions of Java. ### Build and Dist To create a ready to run distribution: ```shell script git clone https://github.com/Consensys/teku.git cd teku && ./gradlew distTar installDist ``` This produces: - Fully packaged distribution in `build/distributions` - Expanded distribution, ready to run in `build/install/teku` ### Build and Test To build, clone this repo and run with `gradle`: ```shell script git clone https://github.com/Consensys/teku.git cd teku && ./gradlew ``` After a successful build, distribution packages are available in `build/distributions`. ### Other Useful Gradle Targets | Target | Builds | |-------------|---------------------------------------------------------| | distTar | Full distribution in build/distributions (as `.tar.gz`) | | distZip | Full distribution in build/distributions (as `.zip`) | | installDist | Expanded distribution in `build/install/teku` | | distDocker | The `consensys/teku` docker image | ## Code Style We use Google's Java coding conventions for the project. To reformat code, run: ```shell script ./gradlew spotlessApply ``` Code style is checked automatically during a build. ## Testing All the unit tests are run as part of the build, but can be explicitly triggered with: ```shell script ./gradlew test ``` ## Special thanks YourKit for providing us with a free profiler open source license.
