Я сгенерировал жирную банку с IntelliJ, и по какой -то причине она не может найти основной класс, выводя ошибку: < /p>
HappyBirthdayWisher\build\libs>java -jar HappyBirthdayWisher-1.0-SNAPSHOT.jar
Error: Could not find or load main class org.example.Main
Caused by: java.lang.ClassNotFoundException: org.example.Main
HappyBirthdayWisher\build\libs>java -cp HappyBirthdayWisher-1.0-SNAPSHOT.jar org.example.Main
Error: Could not find or load main class org.example.Main
Caused by: java.lang.ClassNotFoundException: org.example.Main
< /code>
, хотя, когда я проверял файлы в банке, он ясно существует:
изображение моего Main.class в файле jar < /p>
Вот мой манифест: < /p>
Manifest-Version: 1.0
Main-Class: org.example.Main
< /code>
Я бы очень признателен за любую помощь! > https://jmp.sh/s/rpgx1pmdjhu8rwij4v68
