I noticed that the most recent version of ForgeGradle is 2.0.2 so I figured I'd try to update by making my build.gradle have this (this is directly from the official ForgeGradle plugin site (https://plugins.gradle.org/plugin/net.minecraftforge.gradle.forge):

 

buildscript {
  repositories {
    maven {
      url "https://plugins.gradle.org/m2/"
    }
  }
  dependencies {
    classpath "gradle.plugin.net.minecraftforge.gradle:ForgeGradle:2.0.2"
  }
}

apply plugin: "net.minecraftforge.gradle.forge"

 

But when I do have that and run gradlew setupDecompWorkspace I get an error that says "ForgeGradle 2.0 requires Gradle 2.3 or later".

 

I remember when I updated Gradle to 2.2 but I can't for the life of me remember how to do it. What do I need to do?

 

Nevermind. You have to edit the gradle wrapper properties to pick the right distribution link for 2.8.
