Я новичок в Minecraft Forge, поэтому эта ошибка немного странная для меня. Я правильно настроил Minecraft Forge (по крайней мере, я уверен, что ошибок не было), и когда я запустил ExampleMod, который они дали, все заработало нормально. Я следую этому руководству и все настраиваю в Intellij. Первые несколько шагов тоже работали нормально, пока я не попытался напечатать "Hello World!". Это странная часть, программа actaul не взломала sh, все было нормально, за исключением того факта, что внизу она выдавала ошибку IOException. Я постараюсь уместить все, что происходит на этом снимке экрана: 
Мой mods.toml выглядит следующим образом:
# This is an example mods.toml file. It contains the data relating to the loading mods.
# There are several mandatory fields (#mandatory), and many more that are optional (#optional).
# The overall format is standard TOML format, v0.5.0.
# Note that there are a couple of TOML lists in this file.

Все там выглядит правильно для меня. И работает правильно, просто показывает эту ошибку внизу. Что происходит, и как я могу это исправить?
