In either case, these are individuals who have signed, and are abiding by, the Eclipse IP Policy. The other contributions of the IP log are not significant or are written 100% by employees of the same employer (Obeo) as the Submitting Committer (

All contribution Questionnaires have been completed.

The "provider" field of each plugin is set to "Eclipse Modeling Project".

The "copyright" field of each plugin is set to the copyright owner.

Any third-party logos or trademarks included in the distribution (icons, logos, etc) have been licensed under the EPL.

Non-Code Aspects

Unit tests

1803 unit tests are launched every day.

Code coverage is about:

  • 82 % of the traceability engine
  • 80 % of the compiler
  • 65.7 % of the code generation engine

Code quality

Checkstyle activated on each distinct plug-in.

Eclemma used on a regular basis to improve test coverage.

Yourkit used on a regular basis to improve performances.

Javadoc represents more than 44% of the Java source code.

An Ohloh page is available at


Metamodel definitions and interfaces are considered APIs.

Commitment to provide stand-alone code generation.

Non-API classes are separated from the exposed API through an "internal" namespace.

API Tooling is activated on all plugins to mark exceptions within the exposed API.

Non-API packages are exported with an internal visibility as such they are visible but with an illegal access warning.


The documentation that comes with Acceleo 3.1 is available in the Help menu : Acceleo Model To Text Transformation Language.

Each document of the documentation set deals with a different aspect of mastering Acceleo : There are a Plug-in Overview, a Quick Start, an Android Code Generation Tutorial, a User Guide, several short tutotials to create code generation projects, an Acceleo/OCL operations reference to describe the Acceleo/OCL library, and a Text Production Rules document.

The main documentation is the User Guide because it fully describes each and every feature of Acceleo. From the installation to the execution with a trip through the editing features, it gives an in-depth description of everything there is to know about Acceleo.

Basic Examples are available in the example category : UML to Java, and Ecore to Python.

There is also a basic information page on the Eclipse Wiki
