My folder setup looks like this:

mods/Castledef.zip/mods/CastleDef/Azurn/EntityKnight.class(and other .class files)

mods/Castledef.zip/mods/CastleDef/common

mods/Castledef.zip/mods/CastleDef/client

mods/Castledef.zip/mods/textures/blocks

mods/Castledef.zip/mods/textures/items

 

I would appreciate some help. Thanks!

[kauan99]

I had this same error and for me the problem was different versions of forge src and forge universal. That's probably not your case but if you didn't check that you should.

[Azurn]

It was not that, but thanks anyway. Anyone else?

[Azurn]

Im still having this problem and i have no idea on how to fix it.

[Azurn]

I do not think my folder structure is the problem. When i change it is says:

cpw.mods.fml.common.LoaderException: java.lang.ClassNotFoundException: mods.castledef.azurn.mod_castledef

instead of

java.lang.NoClassDefFoundError: mods/CastleDef/Azurn/EntityKnight

mod_castledef and entityKnight is in the same folder.

[RANKSHANK]

you didn't add a stray @SideOnly right?

[Azurn]

I had a few @SideOnly  in my TileEntity files. Should i have them or should i not have them?
