Empty output model with ATL+ANT and metamodel from xsd file [message #1181218]

Hello,

I have define a MMT with ATL. This have as input a model conforms a metamodel generated from a xsd file using EMF. If I run the transformation with Eclipse configuration it work properly. But when I try execute the transformation with an ANT task the output model is empty. I tried severals configurations:

1. Load de metamodel using its uri. The execution returns an empty model:

<atl.loadModel modelHandler="EMF" name="mmStrutsConfig" metamodel="MOF" uri="platform:/org.eclipse.modisco.struts.config/resource/StrutsConfig.xsd" />

2. Load de metamodel using its path. The execution returns with an error ([atl.loadModel] org.eclipse.m2m.atl.core.ATLCoreException: Error loading file:/C:\Users\victor\Dropbox\ECLIPSE\workspaceMoDisco10\repositorios\org.eclipse.modisco.struts.config\org.eclipse.modisco.struts.config\model\StrutsConfig13.ecore: null):

<atl.loadModel modelHandler="EMF" name="mmStrutsConfig" metamodel="MOF" path="../../org.eclipse.modisco.struts.config/org.eclipse.modisco.struts.config/model/StrutsConfig13.ecore" />

Best regards,

Hello,

Concerning your first case, have you checked that the metamodel is actually well-loaded (for instance by re-serializing it as an Ecore file using "atl.saveModel")?

Hello Hugo,

I check if the metamodel is well-loaded, re-serializing it, and it is well-loaded.

Best regards,
Víctor.

So it is not coming from the metamodel loading.
If you're sure that the transformation itself is OK, thus it can only come from your input model that may be not properly loaded: could you check this too?

The problem was on the model load. I load a wrong file conforms to another metamodel that I use in the transformation. Thank you very much for your help Smile
