EMF Compare/User Guide

Getting Started

Installing EMF Compare

Marketplace Client

Using the bundled Eclipse marketplace client you can install EMF Compare in one click. Just type "emf compare", click on search, and then on install.

Update Site

EMF has been part of the Eclipse release train since Galileo, you can install it using the following update sites, depending on your platform:


http://download.eclipse.org/releases/indigo
http://download.eclipse.org/releases/helios
http://download.eclipse.org/releases/galileo
Please note that the component has at least a2 years compatibility, meaning the indigo release is also compatible with helios, and galileo.

Preference settings

You have to specify for which Model File Types the EMF Compare framework should be used instead of the "normal" eclipse text compare facility. Therefore, please open the preference page "General/Content Types" in your eclipse preferences ("Menu: Window->Preferences...").

Logical Model

The Eclipse Platform logical model API allows to hook in all the workspace and team operations to adapt the user request. It enables, for instance, to add in a commit request new files which are required to keep model consistency.
