Passing ant properties to Eugenia polishing transformation [message #1844185]

I have a Eugenia workflow as shown below. The genmodels are being polished to use a separate target location (source code two). I would like to parameterize this target location, and I understand that the way to do that is to pass in a polishing model. My aim is to pass the parameter from the ant environment. How is this best accomplished? Ideally, I would like to construct the model on the fly.

Or should the polishing transform now be placed outside the eugenia call and open and store the generated genmodel before continuing?

var genModel = GenModel!GenModel.all().first();

genModel.modelDirectory = "/com.codebots.model.emf.commonEntity/src";
genModel.modelPluginID = "com.codebots.model.emf.commonEntity";

var genPackages = genModel.genPackages;

var genPackage = genPackages.first();

genPackage.basePackage = "com.codebots.model.emf";

Update: For this specific use case the data can be derived, so the following can be done:

var genModel = GenModel!GenModel.all().first();

var ecorePackageName : String = genModel.genPackages.first().ecorePackage.name;

var prefix : String = "com.codebots.model.emf";

var pluginID : String = prefix + "." + ecorePackageName;

genModel.modelPluginID = pluginID;
genModel.modelDirectory = "/" + pluginID + "/src";

var genPackages = genModel.genPackages;

var genPackage = genPackages.first();

genPackage.basePackage="com.codebots.model.emf";

self-answer: Yes. Use the code below to load the genmodel into memory, then pass the values you need using the EOL pass mechanisms as shown below. Does not look as elegant as a model, but works just fine. Use an ant macro if you do this a lot.

<epsilon.emf.loadModel name="GenModel" modelFile="@{modelPath}.genmodel" metamodeluri="http://www.eclipse.org/emf/2002/GenModel" />
<epsilon.eol src="GetModelSourceCodeDirectory.eol">
	<model ref="GenModel" />
	<exports ref="modelSourceCodeDirectory" ant="true" />
</epsilon.eol>
