[1.7.2 -- SOLVED] ClassNotFoundException and some other errors

[Bektor]

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

[Bektor]

I run "gradlew setupDecompWorkspace eclipse"

[Bektor]

Ok, thanks!

I will give it a try.

[Bektor]

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

Oh and there is no sound.

 

Bektor

[Bektor]

Set the working directory in the Launch configurations to the eclipse folder in your forge dir.

??

Can you please send a screenshot or explain it a bit more.

What must I change there? (the project, the main class ....)

Bektor

[Bektor]

You have to change the Working Directory, as I said. It's on the Arguments tab.

 

Thanks!

Now everything work!
