Hi, guys. I'm having a small problem installing my first mod. It runs fine in Eclipse, but after running recompile.bat and reobfuscate.bat, and moving the class files/textures into a zip in the mods folder, Minecraft crashes at startup. I've tried a few variations of this (unzipped in mods folder, different levels of directory in the zip, putting class files straight into minecraft.jar) but it keeps saying my basemod file isn't found. I have the same version forge (608) in the development environment and in my minecraft.jar. I assume there's something really basic I've just missed, but help would be appreciated. SOLUTION: In case anyone searches the error, it was related to the directories. The path of directories in the zip needs to be exactly the same as your package in the java class, so mine was: mods/smallimprovements/SmallImprovements.class (and other classes) mods/smallimprovements/textures/items/(item textures) mods/smallimprovements/textures/blocks(block textures) mods/smallimprovements/client/ClientProxy.class If you have more/less subdivisions in your package, you'll need more/less folders to represent them in the file path. My error was caused by zipping the project directory rather than the mods directory. Hope it helps someone in the future; search results gave a lot of people with this problem who solved it but didn't mention the specifics of how. The error message is pretty clear (there's no class file where you told it to look) but a bit cryptic to a newbie in that it doesn't explain the directory doesn't exist.
