Problem running ETL using Epsilon/ANT [message #435476]

Hi;

I'm trying to run my ETL rule using launch.xml (see below). There seems to
be a problem at:
'<epsilon.loadModel name="Ecore" type="EMF">'.

I think I am not sure how to specifiy URI based model and none of the
given examples do so. My etl works fine when I go through "Run
Configuration...".

<?xml version="1.0"?>

<project default="main">
<target name="init">
<property name="models" location="${basedir}/models"/>
<property name="metamodels" location="${basedir}/metamodels"/>
</target>

<target name="loadModels">
<epsilon.loadModel name="EM" type="EMF">
<parameter name="modelFile" value="${models}/car.ecore"/>
<parameter name="metamodelUri"
value="http://www.eclipse.org/emf/2002/Ecore"/>
<parameter name="isMetamodelFileBased" value="false"/>
<parameter name="readOnLoad" value="true"/>
<parameter name="storeOnDisposal" value="false"/>
</epsilon.loadModel>

<epsilon.loadModel name="FM" type="EMF">
<parameter name="modelFile" value="${models}/car.fmm"/>
<parameter name="metamodelFile" value="${metamodels}/fmm.ecore"/>
<parameter name="isMetamodelFileBased" value="true"/>
<parameter name="readOnLoad" value="true"/>
<parameter name="storeOnDisposal" value="false"/>
</epsilon.loadModel>

<epsilon.loadModel name="Ecore" type="EMF">
<parameter name="metamodelUri"
value="http://www.eclipse.org/emf/2002/Ecore"/>
<parameter name="isMetamodelFileBased" value="false"/>
<parameter name="readOnLoad" value="false"/>
<parameter name="storeOnDisposal" value="false"/>
</epsilon.loadModel>

</target>

<target name="main" depends="init,loadModels">
<epsilon.etl src="${basedir}/fmm2ecore.etl">
<model ref="FM"/>
<model ref="EM"/>
<model ref="Ecore"/>
</epsilon.etl>
</target>
</project>

Any help would be great:)
cheers

Hi Ali,

It looks like you want to load the Ecore metamodel as a model named Ecore?

If so, try changing the following lines:

<epsilon.loadModel name="Ecore" type="EMF">
<parameter name="metamodelUri"
value="http://www.eclipse.org/emf/2002/Ecore"/>
<parameter name="isMetamodelFileBased" value="false"/>
<parameter name="readOnLoad" value="false"/>
<parameter name="storeOnDisposal" value="false"/>
</epsilon.loadModel>

to:

<epsilon.loadModel name="Ecore" type="EMF_M2">
<parameter name="metamodelUri"
value="http://www.eclipse.org/emf/2002/Ecore"/>
</epsilon.loadModel>

To load an EMF metamodel, such as Ecore, the EMF_M2 type should be used.
The EMF_M2 type requires only a value for the metamodelUri parameter,
and not for the isMetamodelFileBased, readOnLoad and storeOnDisposal
parameters (which are always false, true and false).

Let me know if this doesn't work, and I'll investigate more thoroughly.

Cheers,
Louis.

Hi Louis;

yes that solved the problem but now it throws an error/warning
"[epsilon.etl - fmm2ecore.etl] Please fix your code to add using
EClass.getEStructuralFeatures() instead of EClass.getEAttributes()",
executes successfully but doesn't generate the target model.

The etl rules execute successfully when I run using configuration. Is
there anything else i need to include in the launch.xml?

Many thanks for your help.

cheers

Hi Ali,

It seems that the EM model is the target of your transformation. If this
is the case you should change

<parameter name="readOnLoad" value="true"/>
<parameter name="storeOnDisposal" value="false"/>

to

<parameter name="readOnLoad" value="false"/>
<parameter name="storeOnDisposal" value="true"/>

so that the model is not read when loaded but is stored when the
workflow has finished.

Regarding the warning, I must admit I haven't come across it. Are you
using 3.5?

Cheers,
Dimitris

Hi Dimitris;

thanks... that solved my problem but the warning is still there. I am
using 3.4.2.

I have another quick question...how can I execute this launch.xml file
using java code as I want this to run on a button click inside my plugin.

many thanks

I have figured out how to do this (as in EtlStandAloneExample), if thats
the only way.

All works fine but the error/warning messages are still there i.e.
"Please fix your code to add using EClass.getEStructuralFeatures() instead
of EClass.getEAttributes()"

Hi Ali,

Running ANT files programmatically in Eclipse is supported by the
ANTRunner class:
http://help.eclipse.org/stable/index.jsp?topic=/org.eclipse. platform.doc.isv/guide/ant_running_buildfiles_programmatical ly.htm

Regarding the warning, I'd suggest following the recommendation and
changing any calls to x.eAttributes.add(...) to
x.eStructuralFeatures().add(...), as eAttributes is a derived feature
(its value is a dynamically calculated subset of eStructuralFeatures).

Cheers,
Dimitris
