Project Manager doesn't need to search the main methods if a project doesn't have the Java nature

Inizia da ProjectCommand.getMainClasses, il punto di ingresso indicato nell’eccezione, e riproduci il problema importando il progetto weblaf collegato con la versione specificata dell’estensione Java di VS Code. Il lavoro è completato quando l’importazione di un progetto senza Java nature non genera più l’eccezione di progetto mancante durante la ricerca delle classi principali.

Steps to reproduce:

• start VS Code with Extension Pack for Java v0.29.2024091906 (pre-release)
• import the weblaf project

You will see the following exception:
