Сохранить Word-файл с Java (runnable JAR)

Question

Я пытаюсь создать приложение, которое может читать информацию из файлов Excel и помещать данные в документ. Документ представляет собой форму шаблона со столбцами. Все работает нормально до сохранения.

Это работает почти так же, как и при запуске программы непосредственно в IntelliJ. Однако, когда я устанавливаю приложение в runnable JAR с Maven - JAR не будет работать.

Файл сохраняется как требуется ... Но новый файл ничего не содержит, если я запускаю приложение из JAR. Когда я запускаю непосредственно в IntelliJ, новый файл создается и открывается, но из 3 столбцов/строк только 2 имеет в нем данные.

Что я могу сделать?

Спасибо расширенному

Большинство probabl y вам не хватает библиотек, когда они экспортируются как JAR. Вы используете Apache POI в качестве внешних библиотек. Внутри IDE были применены все библиотеки, но при экспорте они, кажется, отсутствуют. Просто запустите файл jar из командной строки, чтобы на 100% понять проблему. В IDE, таких как NetBeans, библиотеки экспортируются в отдельную папку с именем lib, ищите аналогичные данные, связанные с вашей IDE.
