Hey guys,

I'm trying to run an .eol file via Ant. I already made sure that it runs in
the sam JRE as Eclipse.

The eol script acts on an Ecore metamodel. Therefore, I'm using expressions
like "Ecore!EPackage.allInstances". However, when I run it, I get this
exception:

[epsilon.eol - adaptMetamodel.eol] EXCEPTION: Type 'Ecore!EPackage' not
found (C:\...\myproject\transformation\adaptMetamodel.eol@7:17)

org.eclipse.epsilon.eol.EolModule.execute(EolModule.java:57)

....

Here is the Ant script that I'm using:

<epsilon.emf.loadModel name="EcarDslModel"
modelfile="${basedir}/../model/fbx.ecore"
metamodeluri="http://www.eclipse.org/emf/2002/Ecore" read="true"
store="true" />

<epsilon.eol src="adaptMetamodel.eol">

<model ref="EcarDslModel" />

</epsilon.eol>

I believe the either the localModel or the eol task don't load the
underlying Ecore metametamodel, which my metamodel is based on. FYI, I can
successfully execute the eol script via an EOL runtime configuration, where
I configured the ecore model as input.

Any suggestions are appreciated.

Thanks, Christoph

Never mind. I got a knot in my brain and mixed up model names. Obviously,
the name I'm assigning while loading the model needs to be the same as when
I pass the model to the eol script.

<epsilon.emf.loadModel name="Ecore"
modelfile="${basedir}/../model/fbx.ecore"
metamodeluri="http://www.eclipse.org/emf/2002/Ecore" read="true"
store="true" />

<epsilon.eol src="adaptMetamodel.eol">
<model ref="Ecore" />
</epsilon.eol>

Greetings, Christoph

Hi Christoph,

Glad you got this working! FYI if you prefer to access the model using a
different name in your EOL program you can use the "as" attribute in
your <model> nested element i.e. <model ref="Ecore" as="SomeOtherName"/>

Cheers,
Dimitris
