Android Build a Weather App (2015) Hooking Up the Model to the View Using Butter Knife for Views

@Bind - Cannot resolve symbol BindView in Butterknife

I attempted to download Butterknife by following the instructions in the GitHub ReadMe, and later by following some of the examples here in the Community postings. The instructions are not hard to follow, yet my @BindView annotation was always underlined in red, revealing an error. Trying to run my program resulted in an error of: Cannot resolve symbol BindView.

I was able to work around the issue by manually adding "import butterknife.BindView;" to my import statements, but I'd like to know why I'm having this problem for future reference, Any assistance would be greatly appreciated. Thanks!

build.gradle (Project: Stormy)

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.3'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

I guess you forgot: apply plugin: 'android-apt' above the dependecies {} in build.gradle(Module: app)

You may also look at this: https://teamtreehouse.com/community/plugin-with-id-androidapt-not-found. That's where I found my answer.
