| [ATL] Error injecting KM3 with Ant [message #62196] |

Hello again.
To automate the build process of my project I created an Ant script to
inject a KM3 meta-model into the corrensponding EMF (Ecore) meta-model, and
ran it from Eclipse.
I'm using the following Ant target, almost cut-n-pasted from the wiki:
<!-- MODEL INJECTION -->
<target name="inject">
<am3.loadModel name="${model}" path="${model}.km3"
metamodel="KM3" modelHandler="EMF">
<injector name="ebnf">
<param name="name" value="KM3" />
</injector>
</am3.loadModel>
<am3.saveModel model="${model}" path="${model}.ecore" />
</target>
${model} is a Ant property set to the model name without extension (the .km3
file is correctly found).
When running the Ant task I get the following:
inject:
[am3.loadModel] GRAVE: no type named 'Metamodel' in metamodel 'ModelName'

BUILD SUCCESSFUL

Although it says "build successful", the resulting Ecore file is empty and
therefore not valid.
What does "no type named 'Metamodel' in metamodel 'ModelName'" mean? I'm
sure the KM3 file is syntax-correct and I can inject it successfully using
the context-menu command provided by the ATL Eclipse plugin.
Thank you in advance.

You were right, I totally forgot to load the KM3 metamodel itself.
However there is still a problem with the following new code:
<target name="inject">
<am3.loadModel modelHandler="EMF" name="KM3"
nsUri="http://www.eclipse.org/gmt/2005/KM3"
metamodel="MOF" />
<am3.loadModel modelHandler="EMF" name="${model}"
path="${model}.km3" metamodel="KM3">
<injector name="ebnf">
<param name="name" value="KM3" />
</injector>
</am3.loadModel>
<am3.saveModel model="${model}" path="${model}.ecore" />
</target>
Unlike Ecore files produced by the Eclipse plugin, the resulting Ecore file
does not use the namespace http://www.eclipse.org/emf/2002/Ecore and
elements like eClass, eAttribute but the KM3 namespace
(http://www.eclipse.org/gmt/2005/KM3) and different elements like Metamodel
and Contents, thus making it incompatible with other EMF tools.
I'm sure that there is a simple way of fixing this problem, maybe adding
another injector parameter... Sorry, I'm a bit newbie with these tools.
Regards.

Hi Lorenzo,
After the injection of your .km3 file, you get a KM3 model (M1 level),
conforming to the KM3 metamodel (M2 level), itself conforming to Ecore
(M3 level). If you want to get a metamodel from the KM3 model, you have
to "promote" this model. You can do this with the transformation KM32Ecore.

Mikael

It worked adding an am3.atl task for the trasformation.
Thanks a lot!
