Development Environment

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.

Follow this link for a step by step installation guide.

Common Environment

Following is a description of the basic configuration:

  • The latest Eclipse Modeling (Or Standard) release
  • EGit
  • [1] JAutoDoc
    • Configure the header template according to your company: Eclipse Preferences -> Java -> JAutodoc
  • Java 1.8:
    • Eclipse Preferences -> Java -> Compiler
    • Eclipse Preferences -> Java -> Installed JREs
    • VM Arguments for debug mode:
-Dosgi.requiredJavaVersion=1.8 -Xms768m -Xmx1024m -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

Oomph includes a way to manage the version changes between two releases as illustrated here

[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:


Getting the code

If you are not using Oomph to set your environment you will need to fetch the code manually.

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 this quick tutorial 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.

Papyrus ServiceRegistry

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

Currently Papyrus provides 2 editors kinds : Diagrams and Table. How to add your own editor kind is explained here Papyrus Developper Guide/How to - Add your own editor in Papyrus

Developer Charter

This is the charter that all papyrus contrubitor must respect.Papyrus Contributor charter


Contributing to Papyrus

Each developer must follow the following rule in addition to the aforementioned Developer Charter.

Retrieve configuration files

The Papyrus Code Templates, Java Cleanup and Java Formatter files are available under the Papyrus repository in the folder releng/templates/ and should be used for all your development on Papyrus.

FAQ How do I control the Java formatter

FAQ How can templates make me the fastest coder ever

The note explains how to install the templates in your environment.

String Externalization/Internalization

  • the goal of the externalization process is to distinguish the string used as messages and visible by the final user and the string required in your code, but not visible for the user,

Follow this link for a guide on externalization in Eclipse.
