[xpand] reference to metamodel not understood by generator [message #495630]

Hi,

I have created a metamodel, which resides in my workspace, and had nsUri "http://planner/1.0".

Now I want to generate code, so I made and xpand file and a workflow-file to run the xpand file:

<workflow>
	<property name="model" value="planner/testmodel.planner"/>
	<property name="src-gen" value="src-gen"/>
	
	<!-- set up EMF for standalone execution -->
	<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup">
		<platformUri value=".."/>
	</bean>
	
	<!-- load model and store it in slot 'model' -->
	<component class="org.eclipse.emf.mwe.utils.Reader">
		<uri value="platform:/resource/${model}"/>
		<modelSlot value="model"/>
	</component>
	
	<!-- check model -->
	<component class="org.eclipse.xtend.check.CheckComponent">
		<metaModel id="mm" class="org.eclipse.xtend.typesystem.emf.EmfRegistryMetaModel"/>
		<checkFile value="metamodel::Checks"/>
		<emfAllChildrenSlot value="model"/>
	</component>
	
	<!-- generate code -->
	<component class="org.eclipse.xpand2.Generator">
		<metaModel idRef="mm"/>
		<expand value="template::Template::main FOR model"/>
		<outlet path="${src-gen}"/>
	</component>
</workflow>

The header of the "planner/testmodel.planner" model is as follows:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:planner="http://planner/1.0">

And I'm getting the following error:

SEVERE: org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'http://planner/1.0' not found. (platform:/resource/planner/testmodel.planner, 3, 54)

Now if I manually change the "xmlns:planner" property of the model to "platform:/resource/my.planner.metamodel/model/planner.ecore ", which is the physical location of the metamodel, it does work. But since the models are generated and the code-generation is part of a chain, I don't want the manually edit the files every time.

So is there a way to let the generator know that http://planner/1.0 refers to the metamodel? I've tried listing the directory of the metamodel as a dependency, but that did not help...

thanks in advance,
RJ

hello

you have to make the ecore known EMF. therefore modify your workflow like this:

<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup">
		<platformUri value=".."/>
               <registerEcoreFile value="platform:/resource/my.planner.metamodel/model/planner.ecore" />
	</bean>

tnx,
