Intégrer Graphify dans un workflow Gradle : du Knowledge Graph au diagramme PlantUML en une commande

:Diagramme d'architecture créé\n(manuellement, à la main);

:Le code évolue\n(nouvelles classes, nouvelles dépendances);

:Diagramme obsolète\n(ne reflète plus le code);

if (Qui met à jour ?) then (Personne)
    :Documentation mensongère;
    note right: Les nouveaux développeurs\nse basent dessus... et font des erreurs
else (Quelqu'un)
    :Mise à jour manuelle\n(2-3 heures de travail);
    note right: Déjà obsolète\nà la prochaine PR
