Bonjour,

J'ai développé une transformation ATL sous Eclipse et j'aimerais bien transformer cette transformation en un plugin java sous Eclipse.

Quelqu'un saurait-il m'indiquer comment faire ?

Merci d'avance votre aide.

J'ai commencé à transformer le module ATL en un plugin Eclipse mais le problème est qu'après la création du plugin, je ne sais pas comment l'exécuter.

Voici le code du fichier .java de ce plugin:

Code :
