I am trying to install Forge build 1047 for 1.7 and am having problems setting it up. I get "cannot find hunk target" errors, causing files to be improperly patched, then compilation errors resulting from improperly patched files.

I get the same error on Build 1024.

Does it have something to do with having JDK 8 installed?

 

After deleting .gradle and build folders

 

 

 

C:\Users\jimbo1qaz\mcforge>gradlew setupDecompWorkspace

Fernflower decompiles things differently on different versions of the JVM.

https://github.com/LexManos/FernFlowerFixer

It's being addressed, until then thats what multiple versions of the jdk, or using setupDevWorkspace is for.
