Hello,

THis is my ANT script

<project default="main">
<target name="loadModels">
<epsilon.emf.loadRegisteredMetamodel metamodeluri="http://org.se/doctrine" />
<epsilon.emf.loadModel name="input" modelfile="./My.ecore" metamodeluri="http://www.eclipse.org/emf/2002/Ecore" store="false" read="true" />
<epsilon.emf.loadModel name="output" modelfile="./Generated.xmi" metamodeluri="http://org.se/doctrine" store="true" read="false" />
</target>

<target name="main" depends="loadModels">
<epsilon.etl uri="platform:plugin/org.se.doctrine.ecore.transformer/ecore2doctrine.etl">
<model ref="input" />
<model ref="output" />
</epsilon.etl>
</target>
</project>

SO how do I refer within epsilon.etl to a plugin's bundled etl file ?

Thank you a lot !

Hi Stephane,

Could you perhaps try platform:/plugin/... in case it makes a difference? Another reason why this might fail could be because ecore2doctrine.etl has not been included in build.properties. If none of these help, please let me know and I'll investigate.

Cheers,
Dimitris
