I am following this tutorial at http://wuppy29.blogspot.nl/2012/08/setting-up-part-2-mcp-and-forge.html

 

Everything goes okay during the install, but when it gets to the recompile part at the end it errors out.

Update your jdk.

Update your jdk.

 

Thanks.

updating, I'm on my tethered cellphone and I'm over my bandwidth so it's going slow.

 

I hope this works, my mods are all whacky in Forge so I need to make new versions.

 

Update the jdk should be on the read first post.

thanks, it worked
