I'm creating a mod, and when compiling I get this problem:

:compileJava                                                               
javacTask: target release 1.6 conflicts with default source release 1.8

Can you post the contents of your build.gradle file?

Sure, just add a line, and I need to use java 8.

I'm not really sure what this comment means, but if you have any version of java 6 installed, I'd suggest uninstalling it (as long as you don't need it for anything).  I've seen many issues with the wrong version of java mysteriously being chosen, so on my own machine I only have one jdk+jre installed (64-bit 1.8).
