Help with Compiling

oh my, here we go

I'm having some ideas of implementing shields (studying and, yes, copying code from vanilla, i don't know how to code in java)

everything was great, eliminated almost all errors, but this one persists:

---------------------------------------------------------------------------------------------

C:\Pylo\MCreator179\forge\build\sources\main\java\mod\mcreator\mcreator_customShieldTest.java:99: error: cannot find symbol
    public EnumAction getItemUseAction(ItemStack stack)
              ^
  symbol:   class EnumAction
  location: class mcreator_customShieldTest
1 error

I don't know what to do...
