[SOLVED][1.7.10]setUnlocalizedName() method not found?

[blfngl]

Hi, I'm getting a very strange error after running gradlew jar and trying to test my mod on an actual minecraft client. It works fine in eclipse, but I'm getting this error when I run it in minecraft:

---- Minecraft Crash Report ----

// I bet Cylons wouldn't have this problem.
