Compile and Build Xpect by Yourself

The Fast Way: Download OOMPH and point it to Xpect.setup.

The Manual Way: Prerequisite: Java 1.8 or newer; Eclipse 3.8 or 4.2 or newer; Xtext 2.9.2.

  1. Clone (this repository)
  2. Import all projects into your Eclipse workspace.
  3. Set target platform to /org.eclipse.xpect.releng/target-platforms/eclipse_4_6_3-xtext_2_9_2/ (Preferences -> Plug-in Development -> Target Platform)
  4. Run /org.eclipse.xpect/src/org/eclipse/xpect/GenerateXpect.mwe2, /org.xtext.example.arithmetics/src/org/eclipse/xpect/example/arithmetics/GenerateXpect.mwe2, /org.xtext.example.domainmodel/src/org/xtext/example/domainmodel/GenerateDomainmodel.mwe2. Now your projects should be without errors markers. Sometimes, even after these steps, several projects still have error markers. However, this is a refresh problem in Eclipse. Simply clean build the projects with error markers will solve the issues.
  5. Run "mvn clean install" to build artefacts and create a p2 repository (formerly known as update site).


This repository has been rewritten to move to the Eclipse Foundation. Find the old history here:
