Hello,
I have a function where I try to load a m1gen-file and then to resolve the resourceSet to get the referenced ecore-file. After that the target of the instantiators should be available. But they aren't. The line System.out.println("instantiator: " + instantiator.getTarget().getName());
@Mojo(name = "generate")
public class GeneratorMojo extends AbstractMojo {
@Parameter
private File m1genFile;
public void execute() throws MojoExecutionException {
List<ClassInstantiator> instantiators = new ArrayList<ClassInstantiator>();
List<Goal> goals = new ArrayList<Goal>();
EPackage.Registry packReg = EPackage.Registry.INSTANCE;
packReg.put(M1genPackage.eNS_URI, M1genPackage.eINSTANCE);
Resource.Factory.Registry fReg = Resource.Factory.Registry.INSTANCE;
Map<String, Object> m = fReg.getExtensionToFactoryMap();
m.put("m1gen", new XMIResourceFactoryImpl());
m.put("ecore", new XMIResourceFactoryImpl());
ResourceSet resSetIn = new ResourceSetImpl();
resSetIn.setPackageRegistry(packReg);
resSetIn.setResourceFactoryRegistry(fReg);
Resource resourceIn = resSetIn.getResource(URI.createURI("file:/" + m1genFile.toString()), true);
try {
resourceIn.load(m);
} catch (IOException e1) {
e1.printStackTrace();
}
EcoreUtil.resolveAll(resSetIn);
TreeIterator<EObject> instances = resourceIn.getAllContents();
M1GenModel m1gen = (M1GenModel) instances.next();
EPackageImpl ePackage = (EPackageImpl) m1gen.getRefers().get(0);
EObject next = null;
while (instances.hasNext()) {
next = instances.next();
if (next instanceof Goal) {
goals.add((Goal) next);
}
if (next instanceof ClassInstantiator) {
instantiators.add((ClassInstantiator) next);
}
}
for (ClassInstantiator instantiator : instantiators) {
System.out.println("instantiator: " + instantiator.getTarget().getName());
}
}
}

Clemens,
What value does m1genFile have? Is it an absolute path? Better use use
URI.createFileURI than what you did (because on Linux it will produce
file://path), assuming the path is absolute in the first place. You can
also try casting instantiator.getTarget() to InternalEObject so you can
inspect the eProxyURI of it.

But they aren't. The line System.out.println("instantiator: " + instantiator.getTarget().getName()); produces every time null value for the name...

Thank you! It works.
I changed it to:
Resource resourceIn = resSetIn.getResource(URI.createFileURI(m1genFile.toString()), true);
m1gen is:
<m1genFile>C:/Users/cschneid/Desktop/workspace-tdg/model/Company.m1gen</m1genFile> [Updated on: Wed, 29 July 2015 07:03] by Moderator |
