Applies as of commit 6170212:

I was excited to try the new code, however I can't seem to compile this, due to problems with the APIs. I tried a number of things -- moving directories around, adding them as submodules by hand, and the --recurse-submodules flag. Currently I have everything under src/main/java, which currently contains baubles, Galacticraft-API, gravestone, nightkosh named exactly as shown. Here's the build error log.

I've also tried having the APIs under the 'api' directory, per what git automatically did when I used '--recurse-submodules'. It also failed. It's acting like it's not finding any of the library files.

Sorry if this is obvious to someone who's dealt with gradle and modding a lot, but I'm new here. What's happening?

Hello. I'm sorry for waiting again.
I made a lot of changes recently so all other mod's API not required anymore. The only thing you should do to get my API - just run in console:

git submodule init
git submodule update
