Ваадин: Смени ОС, теперь я не могу открыть свой проект

0 голосов
/ 16 апреля 2020

Я переустановил свою ОС на моем P C. Я использовал windows 10 при разработке своего проекта, теперь я переключился на Linux, но не могу открыть свой проект Vaadin.

Я получаю HTTP Status 500 - Внутренняя ошибка сервера в браузере при доступе к localhost.

Там написано Exception Report. Root причиной является исключение com.vaadin.flow.server.ServiceException: java .lang.NullPointerException. 

    HTTP Status 500 – Internal Server Error

Type Exception Report

Message com.vaadin.flow.server.ServiceException: java.lang.NullPointerException

Description The server encountered an unexpected condition that prevented it from fulfilling the request.

Я пытался очистить, установить и собрать Maven в проекте, но не повезло, поэтому далеко. Любая помощь в этом?

Хорошо, так что я снова начал работать. В случае, если кто-то наткнется на этот беспорядок, сделайте следующее:

Удалите это из проекта root:

  • node_modules
  • package-lock. json
  • пакет. json
  • webpack.config. js
  • webpack.generated. js

Запустите Maven clean. ... и после этого запустите Maven Build ... подождите, а затем снова запустите с помощью spring-boot: run config.

...
