To ease the development on Papyrus, each member of the team works with basically the same configuration.
One way to manage this is using the Eclipse Installer (by Oomph) to manage your Papyrus development workbench.
Papyrus Oomph Setup Model
The Eclipse Installer provides a set-up model for Papyrus, making it easier than ever to get a complete Eclipse workbench up and running for development on the Papyrus source code. Just download the Oomph Installer from the linked wiki page and follow the simple wizard to create your IDE and import the Papyrus source projects that you want to work on.
Pick any product you like on the first page, but be sure it's the latest release of that product for the Papyrus stream you're working on. For example, if you're working on the Luna service stream of Papyrus, you need the Luna release of Eclipse. On the second page, expand Eclipse.org / Papyrus to see the various components that you can import to work on. Pick any combination of the leaf-level sub-(sub-)projects, even all of them if you like. In the third page where you specify variables such as install location, workspace location, git clone, etc. be sure to choose "Luna" for the Target Platform. This ensures that you will be set up to work on Papyrus Luna (SR1), which is the only development stream currently supported by the setup model (until Mars development gets under way).
Contributing your changes is easy because Oomph will clone the Papyrus Git repository for you and configure Gerrit push.
Amongst possibly other details, the setup model configures:
- your IDE with all of the tools needed to edit and build the source projects you choose
- your workspace with a Git clone and the source projects imported from it that you choose
- a PDE target that includes all of the dependencies required by Papyrus plus the latest nightly build of Papyrus, itself, so that you can import only a subset of the (many) source projects but still run the complete Papyrus toolset in a run-time workbench
- Mylyn queries for current open bugs and enhancements in the Papyrus bugzilla database
- Mylyn queries for the status of the latest Papyrus automated builds, including tests
- Mylyn queries for open Gerrit reviews
- preferences enforcing the Papyrus standard compiler and code formatter/template settings
Please raise bugs if you see any problems in the setup configuration.
When you first launch the Eclipse Installer, it will show the default "simple mode" installer presentation:
You can choose to proceed from here, picking for example the "Eclipse IDE for Committers" package to install, which is the minimal configuration, and later using Oomph to import the Papyrus sources into the workspace (box 1 in the screenshot). However, you may as well select all of the Papyrus content that you need in your development environment now to set everything up in one go. To do that, switch to the "advanced mode": open the dialog tray by clicking on the button (box 2) and select "Advanced Mode..." (box 3). Now you should see the dialog reconfigured as shown below:
Again, the simplest option is to start with the "Eclipse IDE for Committers" package because the setup model will add everything else you need for working on Papyrus's various code and models.
On the second page, pick whatever Papyrus components you need to import into the workspace:
If you need to work on and test the Papyrus setup model, itself, then you should also import the "Papyrus / Developer / Oomph Setup" project (selected in the screenshot above) to configure the workbench to load the Papyrus setup model from your Git checkout instead of from the central Git repository via HTTP.
Next, tell Oomph where to check out the Papyrus repository, where to install Eclipse, and where to create the workspace:
Note that exactly how this page looks will depend on the options you choose for how to manage installation and workspace locations, and whether you have previously used Oomph to install other Eclipse instances (I have).
Note also that if you do not see the target platform that you need in the 'Target Platform' pick-list (for example, Neon to start working on the Papyrus Neon branch that is the master at the time of this writing), then you can just type the name into the field.
The last page summarizes the steps that Oomph will follow to start the installation:
After the newly installed Eclipse instance starts up, it will complete the setup by performing the rest of the tasks that have to be done in the workspace that didn't exist initially. These include the git checkout, importing projects from the checkout into the workspace, creating working sets, Mylyn queries, and more. Once these steps have completed, you will be ready to start working on the Papyrus code.
If you used Oomph's "simple mode" to create your Eclipse workspace, or if you need to make changes to what Papyrus bits you have imported (even for setting up the set-up model redirection), you can do this at any time by launching the Oomph installer wizard from within the Eclipse workbench. Note that you will first have to make the Oomph setup actions available in the toolbar be enabling the preference:
This launches essentially the same wizard as the "advanced mode" of the Oomph Installer.
Following is a description of the basic configuration:
- The latest Eclipse Modeling (Or Standard) release
-  JAutoDoc
- Configure the header template according to your company: Eclipse Preferences -> Java -> JAutodoc
- Java 1.6:
- Eclipse Preferences -> Java -> Compiler
- Eclipse Preferences -> Java -> Installed JREs
- VM Arguments for debug mode:
-Dosgi.requiredJavaVersion=1.6 -Xms768m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=384m -XX:+CMSClassUnloadingEnabled
Required External Plugins
Papyrus may require some external plugins to compile.
The following page maintain a list of Papyrus Required External Plugins
Version Management Tooling
As of late February 2016 in the Neon development cycle, the Papyrus Main plug-ins and features and the Developer Tools are configured for PDE API Tooling and Oomph Version Management validation. One of the value-added capabilities of Oomph is flagging plug-ins and features that aren't included in any other feature, and thus appear to be slipping through a crack in the release. This only works when the workspace has all of the plug-in and feature projects of Papyrus imported.
If your workspace only has a subset of the Papyrus projects imported, then you can tell Oomph that this check is not appropriate by configuring the "check mode" in the Preferences:
[Future] Maven Integration
The Hudson builds are currently implemented with Maven, using Tycho to build Eclipse-compatible artifacts. Therefore, all active plug-in and feature projects have Maven POM files describing them. There is a proposal under consideration to implement Maven Nature provided by M2Eclipse in the Papyrus source projects, to more closely align the Hudson build environment with the developer's local build environment in the Eclipse workbench.
An initial analysis of what would be involved in this change, both in terms of actually implementing the Maven Nature and its impact on Papyrus developers' daily workflow, is captured in this document:
- Adopting Maven Nature in the Papyrus source projects
The specifications are available here: Luna plan

Getting the code
Cloning the Git repository and importing the code
The Papyrus code and some documents are located in a Git repository. In the website http://git.eclipse.org/c/papyrus/org.eclipse.papyrus.git you will find the most recent activity information of the repository and, at the bottom of the page, you will find the URIs of the Git repository (e.g., http://git.eclipse.org/gitroot/papyrus/org.eclipse.papyrus.git).
Follow the next instructions if you never used Git before and want to know how to import the source files of one or more Papyrus plugins in your Eclipse workspace.
First, you have to clone the Papyrus repository. Open the Eclipse import wizard (“File” => “Import”), select “Git” => “Projects from Git” and click “Next”. Select “Clone URI” and click “Next”. Now you will have to enter the repository’s location and connection data. Entering the repository URI will automatically fill some fields. In the case of using the URI http://git.eclipse.org/gitroot/papyrus/org.eclipse.papyrus.git, you will not have to fill any field. Complete any other required fields and hit “Next”.
The Git repository of Papyrus contains many different branches and you must select at least one. Select the branch “streams/1.1-maintenance” if you want to fix code bugs in the Mars version of the Papyrus plugins or “master” if you want to contribute with new features to the latest version of Papyrus called Neon. Click “Next” and select the storage location (e.g., “C:\git”) and the name of the initial branch (e.g., “streams/1.1-maintenance”).
Finally, follow the import projects wizard to select the plugins projects that you want to study or modify, and click “Finish”. You will see all those projects in your workspace.
See the Papyrus project developer resources page for more details
Note about compilable plugins
To know if a downloaded plugin should compile, you can have a look to a Papyrus installation. If the plugin comes with the installation, it should compile!
- The following plugins are not distributed and could be closed (deprecated, not yet provided in the Papyrus distribution or for developpers only):
all plugins of the layer 'developer', except if you need to generate diagrams (in this case you should install GMF Tooling as well) oep.infra.emf.editor oep.infra.emf.embeddededitor oep.infra.emf.newchild oep.team.svn
- Only the follwing projects are currently provided by the Papyrus extra-plugins update site. The others projects can be closed.(They are deprecated, not yet provided in the Papyrus distribution or for developpers only):

Papyrus Coding guidelines
A few points may be a little tricky when coding for Papyrus. Among them:
Papyrus Plugin Naming Scheme and Folders Structure
- Papyrus plugins naming scheme and folder structure used to locate and name plugins is described here: Papyrus_Plugin_Naming_Scheme
Structure and behavior of papyrus
- Presentation of the papyrus structure and the behavior of some parts Papyrus Developer Guide/Papyrus Structure Behavior
Papyrus Command Execution, History, Undo/Redo
- This first document describes the usage of editing domains and gmf/gef/emf commands. See this detailed article Papyrus Developer Guide/Editing Domains and Commands.
- This second document tries to explain how the differents Eclipse Command frameworks work and how they are related. It also explains how commands should be executed in Papyrus, in order to have correct undo/redo.
- Following UML model with code reverse can also be useful:
The ServiceRegistry is one of the main Papyrus component. The idea is that each Papyrus feature should be a service registered to the ServiceRegistry.
The ServiceRegistry should be accessible from any code. It allows to retrieve the components you need to perform your task.
A new implementation of the ServiceRegistry is submitted. The new ServiceRegistry is discussed here Papyrus Developer Guide/Service Registry
Manage Decorators On Papyrus
Papyrus provide services in order To manage decoration on Edit Parts from graphical editor or on icons from model explorer. An application example are describe here: Manage Decorators On Papyrus
