[Solved] Mod works in Eclipse, but crashes after recompiled.

[Over_Code]

I've just starting modding and I'm having some trouble with my mod. It runs fine in Eclipse, but after recompiling and reobfuscating it crashed when I add it to the mods folder.

 

Crash is here:

It could be that the mod is packaged wrong, I couldn't find a simple tutorial. It might not be relevant but here it is just in case. It goes like Mod.zip > morestuffmod > .class files +  client folder with ClientProxy.class

The textures are Mod.zip > assets > morestuffmod > textures > items > the .png files + thumbs.db

It sais it couldn't find the class "overcode.morestuffmod.Base". Are you using a API for your mod? If so, make sure your mod gets loaded after the API.

[Over_Code]

Nope, not using an API. Base.class is my main mod class.

[larsgerrits]

Check if the Mod.zip contains the Base class.

[Over_Code]

Base.class is in the morestuffmod folder with the other .class files

From seeing that it is saying that the mod file directory is overcode/morestuffmod/Base.java in eclipse. When you package your mod it should read as: Mod.zip > overcode > morestuffmod > Base.class. Modding in general is very picky when it comes to file directory listing.

It works, thanks!
