Teku is an open-source Ethereum consensus client that serves as a beacon node and validator client, all wrapped elegantly in Java code. In this guide, we’ll demystify the building process step-by-step, keeping it user-friendly and straightforward. Let’s dive right in!
Preliminary Requirements
Before you embark on your journey with Teku, you’ll need to ensure that you have the following prerequisites:
- Java 21 or higher is required. Note that while building with a more recent version of Java is supported, the resulting build will not work on earlier versions.
Step 1: Clone the Repository
To start building Teku, you’ll first need to clone the official repository. Open your terminal and enter the following command:
git clone https://github.com/Consensys/teku.git
Step 2: Build Distribution
Navigate into the cloned Teku directory and run the Gradle command to create a ready-to-run distribution:
cd teku
./gradlew distTar installDist
This will produce the following:
- A fully packaged distribution in
build/distributions - An expanded distribution, ready to run in
build/install/teku
Step 3: Build and Test
If you want to build and run tests, utilize the following command:
cd teku
./gradlew
Upon success, you’ll find the distribution packages in the build/distributions folder.
Available Gradle Targets
Gradle provides you with several useful targets to create various builds:
distTar– Full distribution inbuild/distributions(as .tar.gz)distZip– Full distribution inbuild/distributions(as .zip)installDist– Expanded distribution inbuild/install/tekudistDocker– The Consensys Teku Docker image
Code Style Guidelines
Teku strictly follows Google’s Java coding conventions. Should you need to reformat the code, run:
./gradlew spotlessApply
The code style is automatically checked during builds, ensuring consistency and quality.
Troubleshooting Step-by-Step
If you run into issues while building or running Teku, here are some common troubleshooting tips:
- Ensure you have the correct version of Java installed. If you encounter compatibility issues, check your Java version with
java -version. - If the build fails, check for any error messages in the terminal. They often provide clues on what went wrong.
