Bonjour à tous

Je cherche à initialiser une nature lors de la création d'un projet (projet que j'ai codé) pour ensuite pouvoir le filtrer

la nature est "fr.valoria.se.bpmp.diagram"

Cela est censé, après que le projet soit créé, modifier le fichier .project et y rajouter :

<natures>fr.valoria.se.bpmp.diagram</natures>

Code :

String natureId = Spem2completeDiagramEditorPlugin.ID;
 
		IProjectDescription projectDescription=null;
		try {
			projectDescription = myProject.getDescription();
		} catch (CoreException e) 
		{
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
 
		String[] ids = projectDescription.getNatureIds();
		String[] newIds = new String[ids.length + 1];
		System.arraycopy(ids,0,newIds,0,ids.length);
		newIds[ids.length] = natureId;
		projectDescription.setNatureIds(newIds);
 
		try {
			myProject.setDescription(projectDescription, IResource.FORCE, null);
		} catch (CoreException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();  //ici ça plante!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
		}

le problème est que la nature n'a pas changé dans le fichier .project...elle est resté vide : <natures></natures>



ça me met cette erreur :
