Getting Started

Installation

Prerequisites:

•  JDK 6 (JDK7 will also work)
•  Eclipse Modeling 3.7.2 or newer (we regularly test and develop with Eclipse 4.2 Juno)
•  Xtext SDK 2.3, Xtend SDK 2.3
  • available from http://download.eclipse.org/modeling/tmf/xtext/updates/composite/releases/
  • it is best to start with the Juno Modeling Tools distribution and then install Xtext and Xtend from the Eclipse Marketplace
  • Warning! There are known issues with the upcoming Xtext/Xtend 2.4 release. As of now, you cannot use EMF-IncQuery with this version.

Some tips for the installation:

• Uncheck "Contact all update sites during install to find required software" to ensure reasonable performance during the installation process
• If you have some other Eclipse Indigo installation, make sure to uninstall older versions of Xtext, Xtend and MWE2 before installing Xtext and Xtend 2.3
• Only check Xtext SDK and Xtend SDK features, the rest will be added automatically
• It is best to use a fresh, new workspace for experimentation

Update site for EMF-IncQuery:

EMF-IncQuery is available from eclipse.org - see http://eclipse.org/incquery/download.php
