Installing other mods to development environment

[Girildo]

Hello everyone,

I am new here and relatively new to minecraft modding. I've looked for this information everyone, but I couldn't find it anywhere, so I decided to ask it here.

I am trying to install other mods into the development environment, I put then the .jar files in forge/mcp/jars/mods, but as I want to run Minecraft from Eclipse it show a black screen and the console outputs "Exception in thread "Minecraft main thread" java.lang.NoClassDefFoundError".

I'd like to install other mods because I want to use items added by other mods in mine, but the wiki page is actually pretty incomplete, as the spoiler says.

 

Thanks in advance.

 

Girildo.

The problem is that every mod is obfuscated (either with notch names or with srg names). The MCP workspace though, is deobfuscated, so it will throw you the NoClassDefError. You can only use these mods if you put their source, if available, into the MCP source.
