Committer Instructions - eclipse-henshin/henshin GitHub Wiki

This page provides two important types of Instructions to Henshin committers: The set-up for working on the codebase with Gerrit, and the instructions for importing projects and resolving their dependencies in your local workspace.

Importing projects into your workspace and resolving dependencies

Henshin's codebase is divided into several plug-in projects with different responsibilies, for example:

• Plug-in org.eclipse.emf.henshin.model: The meta-model
• Plug-in org.eclipse.emf.henshin.diagram: The graphical editor
• Plug-in org.eclipse.emf.henshin.interpreter: The interpeter
• Plug-ins org.eclipse.emf.henshin.{edit,editor}: The tree-based editor

All plug-in projects are contained in the plugins folder in the root directory of our Git repo. Import the plug-ins you want to work on as Eclipse projects into your workspace. Depending on your selection, you may encounter various build errors. To resolve them, install dependencies as necessary. The provided links refer to update sites and cannot be opened in the browser. Use them to install the dependencies in Eclipse via Help -> Install New Software.

• Papyrus for UML: needed for org.eclipse.emf.henshin.diagram. In the update site, find Papyrus in the Modeling category, or by using the filter. Papyrus provides some legacy components of GMF Tooling that are required by Henshin's GMF-based diagram editor.
• Maven Integration for Eclipse: needed for org.eclipse.emf.henshin.giraph.
• Eclipse Xtext: needed for org.eclipse.emf.henshin.text projects. On further build errors, trigger the Xtext generation process: navigate to org.eclipse.emf.henshin.text -> GenerateHenshin_text.mwe2, right click and do Run As -> MWE2 Workflow.
• QVT Operational: needed for org.eclipse.emf.henshin.text.transformation. Navigate to the Metamodel Mappings: right click the project org.eclipse.emf.henshin.text.transformation -> Properties -> Metamodel Mappings. There add mappings for org.eclipse.emf.henshin.model/model/henshin.ecore and org.eclipse.emf.henshin.text/model/generated/Henshin_text.ecore: Add -> Browse -> navigate to .ecore-file.
• EMF Compare: needed for org.eclipse.emf.henshin.interpreter.ui, org.eclipse.emf.henshin.multicda.cpa and org.eclipse.emf.henshin.text.transformation.tests.
• AGG Runtime: needed for org.eclipse.emf.henshin.multicda.cpa. During installation filter for AGG Runtime to find the package.

To resolve further build errors in org.eclipse.emf.henshin.adapters.xtext right click the project -> Properties -> Resource and set the text file encoding to Other: UTF-8.
