Hi,

I register the uml stuff within the generator with the following code:
val resourceSet = new ResourceSetImpl
resourceSet.getPackageRegistry().put(UMLPackage::eNS_URI, UMLPackage::eINSTANCE)
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put(UMLResource::FILE_EXTENSION, UMLResource.Factory::INSTANCE)
val uriMap = resourceSet.getURIConverter().getURIMap()
val url = getClass().getResource("../libs/org.eclipse.uml2.uml.resources_4.1.0.v20130610-0712.jar").toString
val uri = URI::createURI("jar:"+url+"!/")
uriMap.put(URI::createURI(UMLResource::LIBRARIES_PATHMAP), uri.appendSegment("libraries").appendSegment(""))
uriMap.put(URI::createURI(UMLResource::METAMODELS_PATHMAP), uri.appendSegment("metamodels").appendSegment(""))
uriMap.put(URI::createURI(UMLResource::PROFILES_PATHMAP), uri.appendSegment("profiles").appendSegment(""))


The libs are stored in the neighbor package "libs" and added on the build path.
Concerning the plugin I also add them to the plug-in classpath.

It works like a charm when I test the generator with a junit test, but it fails when I run the project as eclipse application. I get the following errors:

I uploaded an example project with the same errors to dropbox, maybe it helps for understanding the problem: https://dl.dropboxusercontent.com/u/19175437/problem.zip
Within the generator you can find the registration/pathmap code. When you run an eclipse application, make a new file with the extension "mydsl". Add some code, save it and the errors should occur in the console.

Thanks in advance for any help! These errors are driving me crazy...

Hmmm

can you please elaborate what you actually try todo.
why do you repackage the uml plugin?

Well, I would also like to use my xtext language inside a standalone application, that's why I thought I should copy the uml2 libs...

So there is a better way of doing it?

Thanks!

Hi

This all seems very strange.

Surely you should be using UM2Ecore to provide *.ecore models that Xtext
works with happily.

I may be mistaken but I doubt that Xtext has any support for UML and I
doubt that there any plans to support the subtleties of associations,
profiles and redefinitions.

If using UML standalone you absolutely must use UMLResourcesUtil.init()
and copying libraries is likely to cause chaos.

Regards

Ed Willink

I just want to generate uml models Wink

Thanks, I will try this out!

Hi,

I now use UMLResourcesUtil.init() and set the uml2 libs by adding them to the required plug-ins inside the "Dependencies" tab of MANIFEST.MF. I also don't use my lib copies...

But from the moment I add the uml2 plugins, a dsl plugin (i.e. xtext example project) stops working inside an eclipse application...

So what are the steps for adding uml2 libs and using them to generate uml2 models inside the generator?

Thanks!

Ok, I made a silly mistake... I added all uml libs, but when I just add org.eclipse.uml2.uml and org.eclipse.uml2.uml.resources to the dependencies it works fine Smile

However profiles don't work, when I test the generator with junit testcases...
