Downloading extra libraries via coremod.

keepcalm · October 13, 2012

I've got a coremod which uses snakeyaml, gson and some other libraries. I'm trying to download them using one ILibrarySet, but for some reason FML seems to be stripping everything except the last section of the folder path.

I'm downloading the libraries from maven, and FML prints out the libraries OK in the log:

2012-10-13 17:23:36 [sEVERE] [ForgeModLoader] There were errors during initial FML setup. Some files failed to download or were otherwise corrupted. You will need to manually obtain the following files from these download links and ensure your lib directory is clean.

2012-10-13 17:23:36 [sEVERE] [ForgeModLoader] <===========>

But when it's downloading them, it shortens it to http://repo.maven.apache.org/maven2/snakeyaml-1.9.jar, for instance.

So to fix this do I have to submit a patch, or am I just doing something wrong?

And here's the log:
