Reproduisez le cas Windows 11 avec JDK 24, le JDK 21 du projet, Gradle, Lombok et la prise en charge de javac activée, en utilisant le build.gradle et les paramètres de l’espace de travail fournis. Commencez par ProjectCommand.getMainClasses et le chemin de code-action passant par CodeActionHandler, RefactorProcessor et MakeStaticRefactoring ; déterminez pourquoi le projet gradle-platform manquant entraîne ces erreurs. Le travail est terminé lorsque les actions de code signalées ne produisent plus les échecs consignés.
