After I setup everything, this error appears every time in my console from eclipse if I'm starting Minecraft and in the ExampleMod class many things are red marked.

 

Here is the error:

[18:03:55] [main/INFO]: Loading tweak class name cpw.mods.fml.common.launcher.FMLTweaker
[18:03:55] [main/ERROR]: Unable to launch

I have created three screenshots, so you can see what I mean:

I hope that you can help me.

Looks like you didn't run either gradel setupDevWorkspace (sp?) or gradel eclipse

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

There is currently a bug in ForgeGradle so you have to run them separately:

 

gradle setupDecompWorkspace (let this finish)

and then: gradle eclipse

 

This didn't help!

Now I get a new error:

The example mod is broken atm. Remove it.

 

Thanks! Now I can start Minecraft and test it :D
