Hi all,

When I click on my .emf file with the right click on mouse, and then Eugenia > Generate Ecore Model I always get this error:

index.php/fa/27455/0/

"An internal error occurred during: "Generating all GMF models".
org/eclipse/emf/emfatic/core/generator/ecore/EcoreGenerator"

Someone can help me on this? Why this error is showing up every time?

I'm using Eclipse Mars.2 Release (4.5.2) on Mac.

Cheers

1. Could you please provide an example metamodel .emf file that causes the problem?

2. Could you please take some working emf examples from the Epsilon website to verify that the problem is not .emf file dependent?

Hi,

with this .emf I get the same error:

Hmm, I have tried with both metamodels. They both work (In case you need it quickly, I put it in the attachment) in my IDE (Windows, Version: Mars.2 Release (4.5.2)). So, the problem should be something related to your Eclipse configuration.

Can we somehow get more detailed description of the error?

The details option just show me this message:

"An internal error occurred during: "Generating all GMF models".
org/eclipse/emf/emfatic/core/generator/ecore/EcoreGenerator"

And now I'm trying to click in my .ecore file and Eugenia > Generate GMF Editor and I'm get this error also:

index.php/fa/27457/0/

"Unhandled error
GC overhead limit exceeded"

Sad

Cool, my guess is, if you increase the heap space of your JVM, then this problem may go away. In your Eclipse configuration file, find the file eclipse.ini and try to increase/set the heap space size. How to do is here: http://stackoverflow.com/questions/8600972/increasing-heap-space-in-eclipse-java-lang-outofmemoryerror .

You need to restart your Eclipse afterwards.

The error

"Unhandled error
GC overhead limit exceeded"

was solved when I changed the heap space but the first one continues going on:

"An internal error occurred during: "Generating all GMF models".
org/eclipse/emf/emfatic/core/generator/ecore/EcoreGenerator"

Is it possible that this error involves something about gmf and eclipse versions ?

Hi,

Is Emfatic installed in your Eclipse? If not, you should install it from http://download.eclipse.org/emfatic/update

Cheers,
Dimitris

Hi Dimitris,

I'm not sure if this link is working because nothing is appearing to me:

index.php/fa/27470/0/

These are my installed softwares:

index.php/fa/27471/0/

Can you help me on this?

Cheers.

Emfatic doesn't seem to be installed in your Eclipse instance. Does un-ticking the "Group items by category" in the first screen do the trick?

Cheers,
Dimitris
