EMF Binding for JSON. Build Status

JSON binding for EMF (Eclipse Modeling Framework) models, that allows serialization and deserialization of EMF Resources in JSON.

This is how a model looks like in JSON format.

{
    "eClass" : "http://www.eclipse.org/emf/2002/Ecore#//EPackage",
    "name" : "model",
    "nsPrefix" : "model",
    "nsURI" : "http://www.example.org/model",
    "eClassifiers" : [
        {
            "eClass" : "http://www.eclipse.org/emf/2002/Ecore#//EClass",
            "name" : "Library"
        }
    ]
}

Development

Development can be done with any Java IDE (Eclipse, IntelliJ, etc...), it does not require any special tooling except Maven.

The tests require some code to be generated from a Xcore model. This generated code is not included in this repository, but is generated when the sources are first build locally, see next section for details.

Building from sources

If you want to build from sources, you will need the Java 7 runtime installed on your system as well as Maven 3. First start by cloning this repository.

git clone https://github.com/emfjson/emfjson-jackson.git

Inside the folder emfjson-jackson, run the following maven command to build and install the project locally.

mvn clean install

This command will call the xtext:generate action that will generate the code from the Xcore model for the tests.

Running tests

The tests can be run with the maven command:

mvn clean test

Or run the class TestSuite from your IDE.
