Issue with programming a mod using FML.

[Sadrien]

I am attempting to follow a tutorial on mod development. I followed exactly, twice. Both times after reaching the step where you run minecraft and see 5 mods loaded, the in development mod being built in an eclipse workspace and the forge mods, it only showed 5 mods. This is the console output.

 

Notes:: Errors are in RED; Script after exiting Minecraft is in ORANGE.

The short question is "Does anyone know how to fix this?" 

really though, What apache product would I reinstall to fix Maven folder issues (I'm sure they will cause problems for other things if they are actually wrong)? Will that even fix this particular issue?

 

The tutorial I am following is found at https://www.youtube.com/watch?v=rmWBP5ifDlw, in case that is relevant to anyone's response.

 

If anyone wants the current code of my project, I am happy to attach source files on request - assuming it is allowed.

Try that.

[Sadrien]

That would make sense XD, thanks, I'll try it.

 

Edit: works now.

Glad that helped.
