How to build Gravitino

Prerequisites

  • Linux or macOS operating system
  • Git
  • A Java Development Kit, version 8 to 17, installed in your environment to launch Gradle
  • Optionally, Docker to run integration tests

:::info Please read the following notes before trying to build Gravitino.

  • Gravitino requires at least JDK8 and at most JDK17 to run Gradle, so you need to install a JDK, versions 8 to 17, to launch the build environment.
  • Gravitino itself supports using JDK8, 11, and 17 to build. The Gravitino Trino connector uses JDK17 to build (to avoid vendor-related issues on some platforms, Gravitino uses the specified Amazon Corretto OpenJDK 17 to build the Trino connector on macOS). You don't have to preinstall the specified JDK environment, as Gradle detects the JDK version needed and downloads it automatically.
  • Gravitino uses the Gradle Java Toolchain to detect and manage JDK versions, it checks the installed JDK by running the ./gradlew javaToolchains command. See Gradle Java Toolchain.
  • Make sure you have installed Docker in your environment if you plan to run integration texts. Without it, some Docker-related tests may not run.
  • macOS uses docker-connector to make the Gravitino Trino connector work with Docker for macOS. See docker-connector, $GRAVITINO_HOME/dev/docker/tools/mac-docker-connector.sh, and $GRAVITINO_HOME/dev/docker/tools/README.md for more details.
  • You can use OrbStack as a replacement for Docker for macOS. See OrbStack. With OrbStack you can run Gravitino integration tests without needing to install docker-connector. :::

Quick start

  1. Clone the Gravitino project.

    git clone git@github.com:datastrato/gravitino.git

  2. Build the Gravitino project.

    cd gravitino
./gradlew build

    The default specified JDK version is 8, if you want to use JDK 11 or 17 to build, modify the property jdkVersion to 11 or 17 in the gradle.properties file, or specify the version with -P, like:

    ./gradlew build -PjdkVersion=11

    Or:

    ./gradlew build -PjdkVersion=17

:::note The first time you build the project, downloading the dependencies may take a while. You can add -x test to skip the tests, by using ./gradlew build -x test.

The built Gravitino libraries are Java 8 compatible, and verified under Java 8, 11, and 17 environments. You can use Java 8, 11, 17 runtimes to run the Gravitino server, no matter which JDK version you use to build the project. :::

  1. Get the Gravitino binary package.

    ./gradlew compileDistribution

    The compileDistribution command creates a distribution directory in the Gravitino root directory.

    The directory structure of the distribution directory is as follows:

:::note The ./gradlew clean command deletes the distribution directory. :::

  1. Assemble the Gravitino distribution package.

    ./gradlew assembleDistribution

    The assembleDistribution command creates gravitino-{version}-bin.tar.gz and gravitino-{version}-bin.tar.gz.sha256 under the distribution directory.

    You can deploy them to your production environment.

:::note The gravitino-{version}-bin.tar.gz file is the Gravitino server distribution package, and the gravitino-{version}-bin.tar.gz.sha256 file is the sha256 checksum file for the Gravitino server distribution package. :::

  1. Assemble the Gravitino Trino connector package

     ./gradlew assembleTrinoConnector

    or

    ./gradlew assembleDistribution

    This creates gravitino-trino-connector-{version}.tar.gz and gravitino-trino-connector-{version}.tar.gz.sha256 under the distribution directory.
