LionWeb Java

Maven Central

This projects requires Java 8, to maximize compatibility.

We require Java 11 for building the project, while the artifacts published are compatible with Java 8.

Using the library

dependencies {
   implementation("io.lionweb.lionweb-java:lionweb-java-2023.1-core:$lionwebVersion")
}

Development

Before opening in IDEA run:

./gradlew setup

This will generate necessary classes.

Core

Contains LionCore (M2) and LionWeb (M1) implementations in Java, including (de-)serializers from/to JSON.

Emf

Contains im/exporters to convert models between LionCore ↔ Ecore and LionWeb ↔ EMF.

Emf-builtins

Some of LionCore's built-in elements have no direct representation in Ecore. This sub-project is an Eclipse project that defines an EPackage builtins to host the equivalent elements in Ecore. The language's nsURI is http://lionweb.io/lionweb-java/emf/core/builtins/2023.1.

Changelog

The Chancelog is here.

Testing

To ensure proper testing coverage we configured Jacoco. You can run ./gradlew jacocoTestReport and then find the report for each module, under build/reports/jacoco.

Update FlatBuffers generated classes

Run from the root of the project:

flatc --java -o core/src/main/java core/src/main/flatbuffers/chunk.fbs
flatc --java -o extensions/src/main/java extensions/src/main/flatbuffers/bulkimport.fbs
