Getting Started

This guide will help you get started with LionWeb JVM with Java, from installation to creating your first project.

Prerequisites​

  • Java 11 or later for using the library (versions 11, 17, 21, and 25 are tested and supported). Java 8 support was dropped in version 1.4.0.
  • Java 17 is required for building.

Installation​

Note that even if you want to use the 2023.1 specs you can use a recent version of LionWeb Java. All versions supports also previous versions of the specs.

Using Gradle​

Add the following to your build.gradle or build.gradle.kts:

dependencies {
    implementation("io.lionweb:lionweb-2024.1-core:$lionwebVersion")
}

Using Maven​

Add the following dependency to your pom.xml:

<dependency>
    <groupId>io.lionweb</groupId>
    <artifactId>lionweb-2024.1-core</artifactId>
    <version>${lionwebVersion}</version>
</dependency>

Or this to your build.gradle.kts:

implementation("io.lionweb:lionweb-2024.1-core:${lionwebVersion}")

Usage Schema​

The typical usage consists in:

  • Authoring a new Language or retrieving it
  • Build models (i.e., trees of LionWeb Nodes) according to the Language(s) defined or used
  • Serialize/De-serialize models for storage and for interoperability with other tools
  • Relay on a LionWeb-compliant repository for storing models and for real-time collaboration with other clients
