So, I'm getting a strange error with a mod I'm making that I can't get much information on. I assume it's related to a circular reference, but I can't figure anything out.

 

I'm using a fresh install of vanilla 1.4.7 with only Forge 6.6.0.497 installed in the jar, and only the mod I'm making is in the coremods folder (and nothing in the mods folder).

The three files referenced are here: [1] [2] [3]

 

I don't have a lot of experience with coremods and access transformers, so I'm probably missing something obvious... Any idea with what could be wrong?

You have to make sure your ASM classes are marked as ignored. Else they will try to transform themselves, which well.. fucks up.

Oh. I remember seeing that in a few code samples I looked at, but I didn't think that part was important.

 

I've got some other errors now, but it looks like something I'll be able to figure out with the objectweb docs.

 

Thanks!
