Hello all,
A new tool for creating Java AST models in EMF is available at:
http://ssel.vub.ac.be/ssel/research/mdd/javaast
This tool creates EMF JavaAST models from Eclipse Java projects. These
models can be used for analysis and model transformation. This tool was
based on the MoDisco Java Abstract Syntax Discovery Tool. These are the
differences with the original tool:
* Use generated EMF JavaAST meta-model.
* Remove AM3 dependencies.
* Add right-click action for Java projects.
* Create AST for entire Java project instead of single Java file
(compilation unit).
Kind regards,
Dennis Wagelaar

Hello Dennis and Dimitri,
Have you take a look to the Java Discoverer ? download : https://bugs.eclipse.org/bugs/show_bug.cgi?id=258281
It is composed of a metamodel J2SE5 and a discoverer that populate J2SE5 models. It provides also a transformation to
KDM. It works in a very similar way of your plugin Dennis (popup menu from a Java project "Modisco Modelplex Knowledge
Discovery -> IntermediateModels -> Discover J2SE5 model from Java project").
In fact, J2SE5 metamodel is not very different from JavaAST, I believe there is only 10/15 different metaclasses. We
have added metaclasses to represents binding between java elements. So relationships are not represented only by a
string, we rebuild also the graph of elements links.
I have not upgraded JavaAST project because of historics (J2SE5 metamodel is born 3 years ago) and I didn't realize that
I could change a lot JavaAST project (I'm a newcomer in Eclipse Community).
And you could also be interested in a model browser that allow metaclass sort, an infinite view of links, etc.

Hi Dennis,
I just installed Java AST, created a hello world plugin project
(attached), and invoked the "Create Java AST model" on it but I got the
following error:

Hello Dennis and Dimitri,
Have you take a look to the Java Discoverer ? download : https://bugs.eclipse.org/bugs/show_bug.cgi?id=258281
It is composed of a metamodel J2SE5 and a discoverer that populate J2SE5 models. It provides also a transformation to
KDM. It works in a very similar way of your plugin Dennis (popup menu from a Java project "Modisco Modelplex Knowledge
Discovery -> IntermediateModels -> Discover J2SE5 model from Java project").
In fact, J2SE5 metamodel is not very different from JavaAST, I believe there is only 10/15 different metaclasses. We
have added metaclasses to represents binding between java elements. So relationships are not represented only by a
string, we rebuild also the graph of elements links.
I have not upgraded JavaAST project because of historics (J2SE5 metamodel is born 3 years ago) and I didn't realize that
I could change a lot JavaAST project (I'm a newcomer in Eclipse Community).
And you could also be interested in a model browser that allow metaclass sort, an infinite view of links, etc.
