Installation

Installation

Update site

The simplest way to install NeoEMF is to use the update-site that is available here. Install the Base component, which provides NeoEMF core classes and utils. Select the backend specific implementation(s) you want to plug in NeoEMF (currently Blueprints and MapDB are available).

Specific backend setup

Backend specific implementations may need configuration files or require other plugins to work properly. These requirements are available in the root of the related subprojects.

Local build

You can build locally NeoEMF by following the instructions in the Build section. It is then possible to install NeoEMF from the local built update-site, or by importing the generated plugins.

Build

NeoEMF

Download the latest release here and unzip it. Go to the root of the extracted directory and run the following command:

mvn clean install

This will build NeoEMF core components and database specific implementations.

(optional) You can also run the tests by using :

mvn test (-pl <core|map|graph>)

NeoEMF : Eclipse plugin

To build NeoEMF Eclipse plugin, you need to run the following command:

mvn clean install -f plugins/eclipse

NeoEMF plugins and update-site are built and stored in your local m2 repository at (.m2/fr/inria/atlanmod/neoemf).

Opening in your IDE

Eclipse

In order to import NeoEMF Git repository in Eclipse, you will need the following plugins in your installation (installable from the software repository of your Eclipse release):

• EGit : v3.4.2 or later
• m2e : v1.5.1 or later

And the following m2e connectors (installable through Preferences > Maven > Discovery / m2e Marketplace):

• Maven SCM Handler for EGit (m2e-egit) : v0.14 or later
• Tycho Project Configurators (Tycho configurator) : v0.8.0 or later

Steps:

• Import the project using File > Import > Maven > Check out Maven Projects from SCM
• Select "git" in the SCM URL field and paste the repository address (https://github.com/atlanmod/NeoEMF.git)
• Choose your workspace and working sets setting and finish

The projects project, parent, core, graph, graph.blueprints and map will be imported and built.

If you want to import the projects generating Eclipse specific plugins (features, update-site), you have to import them by hand using File > Import > Maven > Existing Maven Projects, and select the projects under the "plugins" folder in your local repository.

Issues

If you experience issues installing or using NeoEMF, you can submit an issue on github or contact us at [email protected]

Known issues:

• Only Luna plugins are fetched (the compatibility is not ensured for previous Eclipse versions)
• The Eclipse plugins can not be built if maven can not access internet (it is needed to fetch Luna p2 repositories)
• Sometimes the plugin build crashes and/or freezes during p2 index fetching from Luna repositories. It is generally sufficient to cancel the build (ctrl-c) and to relaunch it.
