Environment setup

Detailed prerequisites for the environment

Overview

Joule is designed to operate with the latest available releases of dependencies and tools, ensuring it incorporates the most current technologies and industry-standard bug fixes.

To get started, ensure you have the necessary prerequisites, including Java Development Kit (JDK), Git and your preferred scripting language. Use Gradle only when you move to building new functionalities in Joule.

For advanced options, consider using GraalVM to enable multi-language support within Joule.

Requirements break down

JDK

Joule works with version 23 of the OpenJDK. Any other lower version will not work with Joule.

Preferred implementation GraalVM CE 23.0.1. Using GraalVM is optional but is strongly recommended to take advantage of user defined expressions and language support.

GraalVM offers enhanced performance for applications and enables multi-language support, which can be beneficial for using dynamic scripting languages within Joule.

OpenJDK Runtime Environment GraalVM CE 23.0.1+11.1 (build 23.0.1+11-jvmci-b01)
OpenJDK 64-Bit Server VM GraalVM CE 23.0.1+11.1 (build 23.0.1+11-jvmci-b01, mixed mode, sharing)

Gradle

Install Gradle 9.0.0

Gradle is required to manage Joule’s build lifecycle. It provides build automation for multi-language applications, enhancing the overall development process.

Git

Git is essential for cloning and managing Joule repositories. Ensure you have the latest version installed to avoid compatibility issues with repository operations.
