Unable to run mods on Test Environment in 1.14.4

Can not reproduce
Issue description

As the topic said, I just have discovered that it is not possible to install mods into test environment, every time there is a mod placed in mods folder it gives a random crash error usually saying error during preinitializing or function error.

Mods I have used to test that:
JEI - If this one not working than there is something really wrong
Project E
Iron Chest
World Edit
Fast Workbench
Toast Control

Issue comments

Note: They work fine in Normal MC installation

  1. java.lang.NoSuchMethodError: net.minecraft.client.Minecraft.func_71410_x()Lnet/minecraft/client/Minecraft;

This error is unrelated from MCreator, most likely incompatibility between Forge version and one of the mods, NoSuchMethodError only appears in such cases in crash logs.

Based on next line from stack trace, it is JEI:

  1.     at mezz.jei.JustEnoughItems.lambda$clientStart$3(JustEnoughItems.java:34) ~[?:6.0.0.27] {re:classloading}

Weird, they don't have errors in normal mc when I tested them with 28.1.116 forge
anyway here is the log from ProjectE attempt if you want take last look at this: https://pastebin.com/e1pWR4qs
Also thanks for the help :)

  1. java.lang.NoSuchFieldError: field_185512_D

  2.     at moze_intel.projecte.gameObjs.blocks.BlockDirection.<clinit>(BlockDirection.java:24) ~[?:?]

  3.     at moze_intel.projecte.gameObjs.ObjHandler.<clinit>(ObjHandler.java:154) ~[?:?]

This indicates incompatibility between mod API versions, or Forge versions or something like this. Unfortunately I can not see which mod causes this from the logs.

Hmmm, it might be actuall issue with forge development kit itself,
let's just leave that and see if next forge stable version will have same issue
