Я использую открытую исходную программу для minecraft, и я пытаюсь ее отредактировать, но немного сложно. Я распространяю свою пусковую установку, и все люди и половина из них сталкиваются с этой проблемой NullPointer, а остальные хорошо работают. Пусковая установка запускается, но затем, где предполагается, что это значок модпака, ничего нет. Я проверил, что это не проблема URL брандмауэра и Infact в консоли лог написано так:JAVA Exception in thread «Thread-2» java.lang.NullPointerException

Я думал, что это была проблема установки некоторых функции, но я не уверен. Если вы не можете решить проблему, вызовите слишком мало значений по умолчанию, я могу добавить некоторые из них или вы могли бы дать мне несколько идей о том, как их решить?
