Niente da fare non riesco a cavare il ragno dal buco…
Ho un progetto 1 in Spring Boot su IntelliJ che funziona alla perfezione ed un progetto 2 in Docker che funziona alla perfezione. Il progetto 1 funziona perché in locale viene renderizzato perfettamente nel browser. Il progetto 2 funziona alla perfezione perché se provo ad usarlo con un .jar di un’altra WebApp in Spring Boot non fa una piega.
Io penso ad un’errata scrittura del file pom.xml, dei file properties oppure ad una errata configurazione dell’IDE (quest’ultima meno probabile).
Sono giorni che sto smanetto e non so più dove sbattere la testa.
In pratica sul terminale di Linux (per testare il progetto 2 uso una VM Linux di vmware) ottengo questo errore:
no main manifest attribute, in /demoapp/Nomefilejar-9.0.jar
Il file .jar che ottengo è anche troppo piccolo,
solo 5MB, ma dovrebbe essere come minimo di 20MB.
