Requiring users to put it into the libs folder is okay for me. It doesn't make much sense to create a core mod just do load a library anyways... and thats what i meant with "other mods being able to use it" - not to rely on a certain core mod, but rather on a jar file being present in the lib folder.
However, the library doesn't appear to get loaded when i place it in "lib", Forge exits when encountering a java.lang.NoClassDefFoundError exception. I don't have this problem starting Minecraft from the IDE, where i have the lib in the classpath. Maybe i overlooked something or i'm just a total noob, but how would i get the lib loaded so its classes are available to my mod code?
