[Acceleo] problem with primitive types when executed as Java application [message #902957]

As a consequence of this issue (http://www.eclipse.org/forums/index.php/t/369676/) I have an acceleo transformation which produces the desired output only when executed as a Java Application.

I have however notice that in this case there are some problems with primitive types. suppose I have a classifier property called att typed with an Integer UML Primitive type. If I run (as a Java Application) this code

   [att.type/] [att.type.name/]

I get

org.eclipse.uml2.uml.internal.impl.PrimitiveTypeImpl@548eb (eProxyURI: pathmap://UML_LIBRARIES/UMLPrimitiveTypes.library.uml#Integer)

Hi Andrea,

When using UML in standalone (Java Application), you need to properly register everything it needs, including the primitive types. See the UML FAQ.

The bits needed to register their models and factories can be done in your generated java launcher, within the "register*" methods.

Hi,

You should use something like this in the method registerPackages of your generator:

Map uriMap = resourceSet.getURIConverter().getURIMap();
URI uri = URI.createURI("platform:/plugin/org.eclipse.uml2.uml.resources/");
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(""));

But for the stand alone, the path of the jar org.eclipse.uml2.uml.resources is not "platform:/plugin/org.eclipse.uml2.uml.resources/" but the absolute path of the jar.

Regards,

Stephane Begaudeau

Hello Stephane and Laurent

I got the same problem with instances of PrimitiveType, when started to write a Swift code generator from class diagrams built using Papyrus. My class diagram has a number of classes containing properties typed by elements of UML Primitive Types (String and Integer), and when trying to get the names of such primitive types as strings ("String" and "Integer") I got blank, just like Andrea indicated previously. More details on my problem is in this thread: https://www.eclipse.org/forums/index.php/t/1094565/ I am running Acceleo 3.7.3... and Papyrus 4.0.0... on top of Eclipse Photon and my generator is not running as a stand-alone application.

My question is: do I have to modify the registerPackages() method in the Generator.java file? What modifications do I have to do to register the UML Primitive Type package? I am not really understanding this registering stuff and your assistance will be really appreciated.

Thank in advance for your help. Kindest regards.

Hello,

Thank you for the explanations about how to register packages, that's now pretty clear for eclipse plateform or standalone when we know the absolute path of the JAR.

How the Base URI for the Jar is supposed to be set when the dependency is retrieved by Maven - using org.eclipse.acceleo.maven.launcher" plugin for instance?
Is there a specific scheme available or another portable way to specify it?

Thank you for your help
Best regards.
