[XCore] Xtext-maven-plugin with xcore lead to exception [message #1705483]

Hi modeling heroes!

I'm creating a tycho/xcore/xtext project, and encounters an issue when mixing xcore and xtext.

While building, I got this exception on my xcore powered project:

And finally the grammar (fairly simple):

@Ecore(nsURI="http://www.osgiliath.net/metamodels/classes/0.0.1")
package net.osgiliath.modeler.metamodel.classes


class ONamedElement {
	String name
}
class OElements extends ONamedElement {
	contains OPackage[] packages
	contains OParametrizedClassifier[] parametrizedClassifiers
}
class OPackage extends ONamedElement {
	contains OPackage[] subPackages opposite superPackage
	container OPackage superPackage opposite subPackages
	contains OClassifier[] classifiers opposite ownerPackage
	derived String FQN get
	{
		 var FQN = name
		 var OPackage current = superPackage
		 while (null != current) {
		 	FQN=current.name + "." + FQN
		 	current = current.superPackage
		 } 
		 return FQN
	}
}

class OType extends ONamedElement{
}

enum VISIBILITY {
	public as '+' = 0
	protected as '#' = 1
	private as '-' = 2
}
class OVisibilityAble extends OType {
	VISIBILITY visibility
}
class OStaticable extends OType {
	boolean isStatic = "false"
}
class OFinalizable extends OType {
	Boolean isFinal = "false"
}
class OAbstractable {
	Boolean isAbstract = "false"
}
class OClassifier extends OType {
	container OPackage ownerPackage opposite classifiers
	derived String fQN get
	{
		 return ownerPackage.FQN + "." + name
	}
	op String toString() {
		return FQN
	}
	
}
class OParameter extends ONamedElement, OFinalizable {
	refers OType oType
}
class OMethod extends ONamedElement, OVisibilityAble, OStaticable, OFinalizable, OAbstractable {
	refers OType returnType
	contains OParameter[] parameters
}
class OMethodable extends OClassifier {
	contains OMethod[] methods
}
class OInterface extends OVisibilityAble,OMethodable {
	refers OInterface[] extensions
}
class OAttribute extends OParameter, OVisibilityAble, OStaticable {

	refers OClass extensions 
	contains OAttribute[] attributes
}
class OParametrizedClassifier extends OClassifier {
	refers OClassifier classifier
	refers OClassifier[] parametrizedClassifiers
}

I also have a grammar using this xcore model, that throws the same exception when I reference this xcore. But when I export the genmodel then reference it for the grammar, it passes without any issue.

Any idea on this? I looked at eclipse bugs or any other source, but didn't find any similar issue.

Best regards,

Charlie

Charlie,

This should be fixed in the maintenance stream

Hi Ed,

Thank you for the answer, I will try. Unfortunately, these deps must be referenced as Maven dependencies (not as p2 one) because they're necessary for the m-xtext-pg.
Can you ping this thread while available?

Best regards,
Charlie

Charlie,

They won't end up there because I do something. In fact I have no idea
how they'd ever end up there. Maybe Dennis knows...

Hello Charlie,
I've just released xcore 1.3.1 maven artifacts, where the issue you had is fixed.
It will be available in maven central soon.

Regards,
Dennis.
