I would like to wrap an existing Java API as EMF Ecore. I would like to document the model explicitly using Ecore and I am looking at creating a lifting transformation. I am considering using EMC-JDT for this purpose. Is there any obvious reason why this would not work?

Hi Jörn,

The JDT driver was recently moved to the Epsilon repo and will be part of 2.4 when it's released within the next few weeks. Documentation-wise, there's only this page [1] for now, which we plan to turn into an article on Epsilon's website. There are also two examples in the repo (org.eclipse.epsilon.examples.jdt.* under [2]). I'm not sure how easy it would be to run JDT (on which the driver depends) in a headless mode but other than that, I can't think of any reasons not to give the driver a spin.

Best,
Dimitris

Hi Dimitris,

That is very good news. I have read the code in the lab and for this stage interactive ant-driven will probably be enough. Very happy that it will be in 2.4. WIsh me luck. JDT drives PDE/Build, which is headless and given that Epsilon is generally file-based and avoids call-loading this might actually work headless already.

Best,

JG
