java.lang.NoSuchFieldException: minecraftDir Error

[Taji34]

I followed the instructions found here: http://www.minecraftforge.net/wiki/NetBeans but when I try to run Minecraft in Netbeans I get the following error:

java.lang.NoSuchFieldException: minecraftDir
at java.lang.Class.getDeclaredField(Class.java:1899)
at Start.main(Start.java:17)

I haven't edited anything with Minecraft yet, I was just checking to make sure it ran correctly. I am using the recommended build of forge (as of Oct 15, build 303). What's wrong? Did I do something wrong somewhere? Thanks for your help.

Im gunna say you didnt link with the decompiled source properly, as that field should exist just fine. But it wont if you link against the obfusicated classes.

So I did some snooping around and looked at the MCP tutorial and figured out that I needed to change some settings, but now it runs but then give out an error message:

Any ideas?

 

EDIT: I figured out my problem! The library path wasn't pointing to the right place, so it couldn't find some files. Thanks for the help!
