Xcore - Using annotations in IDE [message #1221899]

Hi,

i got the following issue:

If i am using Xcore to define a model and i would like to use the annotations defined in org.eclipse.emf.ecore.xcore.lib, i have to import the project into workspace. Otherwise i am getting following error message in the editor:
"Couldn't resolve reference to XAnnotationDirective 'GenModel'."

Is there a way to avoid importing the lib bundle into workspace?

Thanks, Florian

simply use a plugin project with a dependency doesnt work?
it works for the one created with the xcore wizard

@GenModel(copyrightText="Test")
package test

annotation "http://www.eclipse.org/emf/2002/GenModel" as genmodel

class Entity {
	
}

alternatively the following works as well

@GenModel(copyrightText="Test")
package test

import GenModel

class Entity {
	
}

@GenModel(copyrightText="Test2")
package test

class Entity {
	
}

Thanks, "import GenModel". That was the clou...

Thanks Florian

P.S:

seems you need at least a import yes.
the other one did not survive a clean build

It should be sufficient for the project to have a dependency on
org.eclipse.emf.ecore.xcore.lib and for that bundle to be in your target
platform.

Hi Ed,

a simple dependency does not work. Without an import statement i have to import the xcore.lib bundle into the workspace.

Best, Florian

Florian,

I just tested this

@GenModel(prefix="Tester")
@Ecore(nsURI="http://www.example.org/test")
package org.example.test

class Test
{
}

and it works fine without imports and without xcore.lib in the workspace
(including the Ecore annotation). In general, I expect the things
declared in XcoreLang.xcore to be visible everywhere without imports.

package xcore.lang

annotation "http://www.eclipse.org/emf/2002/Ecore" as Ecore
annotation "http:///org/eclipse/emf/ecore/util/ExtendedMetaData" as
ExtendedMetaData
annotation "http://www.eclipse.org/emf/2002/GenModel" as GenModel

Via the properties view you can set GenModel properties and they're
converted to annotations with this basic assumption.

Which version of Xcore are you using?
