[Acceleo] Type of UML attribute/property (Acceleo 4.3.0, Eclipse SR2)? [message #1265583]

Hi,

I have a Papyrus model in which a class has an attribute with of the
type String from the UML Primitive Types. Based on the getting started
tutorial I expected the following to work and to result in "String
attributeName":

[for (p: Property | aClass.attribute) separator('\n')]
[p.type.name/] [p.name/];
[/for]

But "[p.type.name/]" does not result in any output. Am I missing
something? What should I do?

TIA

Joost

Cheers,

Joost

Yes you do.

Saidly it is a bit ugly, but you need to do as it is described here:
https://wiki.eclipse.org/MDT/UML2/FAQ#What.27s_required_to_load_a_UML_.28.uml.29_resource_from_a_standalone_application.3F

Don't forget the

@generated NOT

It works for me, customize your eclipse location and the versions:

    /**
     * This can be used to update the resource set's package registry with all needed EPackages.
     * 
     * @param resourceSet
     *            The resource set which registry has to be updated.
     * @generated NOT
     */
    @Override
    public void registerPackages(ResourceSet resourceSet) {
        super.registerPackages(resourceSet);
        if (!isInWorkspace(org.eclipse.uml2.uml.UMLPackage.class)) {
            resourceSet.getPackageRegistry().put(org.eclipse.uml2.uml.UMLPackage.eINSTANCE.getNsURI(), org.eclipse.uml2.uml.UMLPackage.eINSTANCE);
        }
        
        resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put(UMLResource.FILE_EXTENSION, UMLResource.Factory.INSTANCE);
        Map uriMap = resourceSet.getURIConverter().getURIMap();
        URI uri = URI.createURI("jar:file:/c:/eclipse/eclipse-modeling-luna-R-win32-x86_64/plugins/org.eclipse.uml2.uml.resources_5.0.0.v20140602-0749.jar!/"); // for example
        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(""));
...
}

Hi

As of Luna UMLReourcesUtil.init(ResourceSet) does all the setup scanning
the classpath top discover the JAR spelling. Acceleo could call it for
you but it doesn't.

(In Kepler the pathmap assignments were still needed.)

Hi,

I have exactly the same problem but the given solution did not solve the problem for me.
Below, the code of my "registerPackages" function (with suggested moficiations):

    /**

Any other idea?

Hi,

I finally found how to make it works. I am not sure how I did it, but here is the code of my "registerPackages" function now:

    /**
     * This can be used to update the resource set's package registry with all needed EPackages.
     * 
     * @param resourceSet
     *            The resource set which registry has to be updated.
     * @generated NOT
     */
    @Override
    public void registerPackages(ResourceSet resourceSet) {
        super.registerPackages(resourceSet);
        if (!isInWorkspace(org.eclipse.uml2.types.TypesPackage.class)) {
            resourceSet.getPackageRegistry().put(org.eclipse.uml2.types.TypesPackage.eINSTANCE.getNsURI(), org.eclipse.uml2.types.TypesPackage.eINSTANCE);
        }
        if (!isInWorkspace(org.eclipse.uml2.uml.UMLPackage.class)) {
            resourceSet.getPackageRegistry().put(org.eclipse.uml2.uml.UMLPackage.eINSTANCE.getNsURI(), org.eclipse.uml2.uml.UMLPackage.eINSTANCE);
        }
        if (!isInWorkspace(org.eclipse.papyrus.C_Cpp.C_CppPackage.class)) {
            resourceSet.getPackageRegistry().put(org.eclipse.papyrus.C_Cpp.C_CppPackage.eINSTANCE.getNsURI(), org.eclipse.papyrus.C_Cpp.C_CppPackage.eINSTANCE);
        }
        if (!isInWorkspace(org.eclipse.emf.ecore.EcorePackage.class)) {
            resourceSet.getPackageRegistry().put(org.eclipse.emf.ecore.EcorePackage.eINSTANCE.getNsURI(), org.eclipse.emf.ecore.EcorePackage.eINSTANCE);
        }
        
        
        Map<URI, URI> uriMap = resourceSet.getURIConverter().getURIMap();
        URI uri = URI.createURI("jar:file:/C:/Users/.../eclipse/plugins/org.eclipse.uml2.uml.resources_5.0.0.v20140519-1951.jar!/");
        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(""));
    }

I have also modified the "registerResourceFactories" function (because I am loading .uml files, not .xmi files), I do not know if it has really an effect:

    /**
     * This can be used to update the resource set's resource factory registry with all needed factories.
     * 
     * @param resourceSet
     *            The resource set which registry has to be updated.
     * @generated NOT
     */
    @Override
    public void registerResourceFactories(ResourceSet resourceSet) {
        super.registerResourceFactories(resourceSet);
        resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("uml", new org.eclipse.emf.ecore.xmi.impl.XMIResourceFactoryImpl());
    }

Hi,
I got the same problem.

The type of attributes or operations can't be accessed by [p.type.name/].
I tried the solutions provided in this thread, but there are some errors in the Generate.Java.

I also changed the Runner from Java Application to Acceleo plugin, but it didn't work.

Previously, my Acceleo code running well on Eclipse Modeling Juno.
I attempted to run on Eclipse Neon and this problem happened

Any idea what should I do?

regards,
Maya

Hi

Three years later you probably do not have the same problem.

Some errors in Generate.java sound like it needs investigating.

Have you an error in console? Are you certain that p is in the good type and not undefined?

Hello guys,
I had the same problem right now and solved it (I have Eclipse Mars 2 with Acceleo 3.7).

First of all, I copied the code from Ol Reak into my java file, the one which got the same name as my main ".mtl" generator file and changed everything according to my system

URI uri = URI.createURI("jar:file:/C:/Users/.../eclipse/plugins/org.eclipse.uml2.uml.resources_5.0.0.v20140519-1951.jar!/");

Here you have to fill in the path where your eclipse is installed and find out the actual name of the jar file with your version, for instance for me it is

URI uri = URI.createURI("jar:file:/C:/eclipse-php-mars-R-win32/eclipse/plugins/org.eclipse.uml2.uml.resources_5.1.0.v20160201-0816.jar!/");

Then the compiler nagged, that he didn't know Map and UMLResource,
so I added to the imports at the top of my file

import java.util.Map;
import org.eclipse.uml2.uml.resource.UMLResource;

Then, last not least, he told me that in registerPackages concerning

if (!isInWorkspace(org.eclipse.papyrus.C_Cpp.C_CppPackage.class)) {
    resourceSet.getPackageRegistry().put(org.eclipse.papyrus.C_Cpp.C_CppPackage.eINSTANCE.getNsURI(), org.eclipse.papyrus.C_Cpp.C_CppPackage.eINSTANCE);
        }

org.eclipse.papyrus.C_Cpp.C_CppPackage couldn't be used as a type, or something like that.

But I found this

https://git.eclipse.org/c/papyrus/org.eclipse.papyrus.git/commit/?id=8825c18b6e8926b45269c40d9af43c3c064b0048

It seems the project org.eclipse.papyrus.C_Cpp was remodeled to be part of
org.eclipse.papyrus.cpp.

So I tried to add that in my MANIFEST at Dependencies, turned out, you need
org.eclipse.papyrus.cpp.profile to get it working.
