Error upon decompiling forge SRC

[dannydobbi]

Hi, I recently decided to start a fresh / updated MCP workspace, I am now getting an error whenever I attempt to decompile it, I have tried searching the web for answers and was unable to figure what to do.

 

A few primary things to clear:

JRE - Up to date

JDK - Up to date

Forge SRC - !.6.4 Latest

 

Error Received :

Steps done:

1, Download forge SRC

2, extract forge folder

3, open install.bat and let it finish installing libraries and various other things.

 

Thanks for any help in advance.

Use build .964 with ForgeGradle, .965 is only for mod users, not mod makers.

Oh okay, thank you very much.
